Dishwasher noise is the one spec buyers research hardest and understand least. Manufacturers print a single dB(A) number on the spec sheet, and everything from social media posts to retail listings treats that number as the whole story. It is not. Installation quality, floor material, cabinet construction and even which cycle you pick can move the perceived noise of the same machine by a wide margin.
That is why this guide leads with measurements instead of adjectives. We ranked these eight models on published decibel ratings, then cross-checked those numbers against owner reports about what the machines actually sound like in a real kitchen, how they handle drying, and how they hold up over time. The result is a list that tells you not just which dishwasher is quietest on paper, but which one will still feel quiet on a Tuesday night with the whole family home.
Across the group, published noise ratings run from 40 dB on a countertop unit to 52 dB on a pair of 18-inch built-ins. The gap matters more than most shoppers expect: 40 dB sits under a whisper, while 52 dB is louder than an average refrigerator hum running in the same kitchen. If you live in an open-plan space, work from home, or have a downstairs neighbor, that spread decides which models are usable and which are not. We also cover the same noise-conscious buying logic in our guides to quiet window air conditioners and quiet portable air conditioners, where the decibel ratings matter just as much.

One caution before you read the individual reviews: no manufacturer publishes peak noise, only an average. A 45 dBA machine can spike briefly when the drain pump empties at the end of a cycle, and that spike is often the moment people describe as loud. We have called that out wherever owner reports mention it.
1. EUHOMY Countertop Dishwasher – The Editor’s Choice Number in the Group at 40 dB
EUHOMY Countertop Dishwasher Portable, 6 Programs with 40 dB, No Hookup
40 dB operation
5 liter tank no hookup
30+ items per load
6 programs plus 73 hour vent
28.6 lb
Pros
- Quietest published rating in the group at 40 dB
- No plumbing or installation needed
- Handles 30+ items and plates up to 10.25 inches
- Long 60 minute hot air dry plus 73 hours of ventilation
- Light enough to move between rooms
Cons
- Drying is the most common complaint
- Small cookware only
- Dishes need thorough scraping first
At 40 dB, this is the quietest machine in the field by a clear margin, and it reaches that number in a way no built-in can. The unit weighs 28.6 pounds, runs on a 120-volt plug, and connects to nothing. You fill a 5-liter tank with the included pitcher or clip the 4.92-foot hose to a faucet, and the machine does the rest. For anyone in a rental, a dorm, a studio apartment or a kitchen mid-renovation, that removes the single biggest reason people skip a dishwasher entirely.
The cleaning performance is genuinely surprising for the size. Dual spray arms cover 360 degrees and the rack takes 30+ items, including plates up to 10.25 inches, which is more than many people expect from a countertop format. The cycle list covers the usual ground: Normal, ECO, Quick, Baby Care or Strong, Fruit, and Dry.
What it cannot do is handle your cookware. This is a dishes-and-small-bowls machine, not a pot-and-pan machine, and buying it expecting a 45-pound casserole to come out clean will end badly. Owners also consistently report that scraping is not optional; food still sitting on a plate goes through the cycle and comes out attached.
The drying situation is the model’s one real weakness, and it is the complaint that shows up again and again in reviews. There is a 60-minute hot air dry program and up to 73 hours of post-cycle ventilation, but a handful of owners report the drying performance stops working properly after early use, and pooled water in the bottom of the rack is a recurring theme. Plan on air-drying overnight, or run Dry as its own cycle after the wash finishes.
When this quiet countertop model makes sense?
This is the dishwasher to buy if noise is your top priority and plumbing is either unavailable or unwanted. Forty decibels is quiet enough to run a full cycle while holding a video call in the next room, and owners working from home confirm that in practice. It also solves the small-kitchen problem entirely, since 16.85 by 16.73 inches fits on a counter or a rolling cart under a low cabinet.
It is equally a good fit for a second household dishwasher in a garage, a pool house or a vacation rental, where the machine gets used twice a week and does not need to be built in.
When it is the wrong quiet dishwasher for you?
Buy something else if you cook daily with cast iron, stainless pots or sheet-pan sized bakeware. The basket simply does not have the volume, and the smaller the cavity, the more often you will find yourself re-arranging mid-cycle because the rack pegs are unevenly spaced.
It is also a poor fit if you want finished, dry dishes immediately after a cycle. The hot air dry program is real but modest, and this is not a machine you can load and unload wet-free in one pass.
2. EdgeStar 18 Inch Built-In Dishwasher – 8 Place Settings With a Full Stainless Tub
EdgeStar BIDW1802SS 18 Inch Wide 8 Place Setting Built-In Dishwasher
52 dB operation
8 place settings
18-inch built-in
Stainless tub, racks and basket
62.8 lb
Pros
- Stainless steel tub with stainless racks and basket
- 8 place settings in a standard 18-inch opening
- 6 cycles plus sanitize hi-temp and heated dry
- Leakage sensor auto-shutoff
Cons
- 52 dB is the loudest rating in the group
- Push-button controls feel dated
- Only a 1-year manufacturer warranty
This is the proven workhorse of the roundup, with 844 reviews behind it, and it is the model most often recommended to people replacing an aging 18-inch unit or an old trash compactor. The 18-inch body measures 17.63 by 22.44 by 32.5 inches and needs a 32.5 by 17.75 by 23 inch cutout, so it drops into most standard 18-inch openings without cabinet work.
Where it earns its reputation is the interior. The tub, the racks and the silverware basket are all stainless steel, which is the configuration that tends to age best and to add a little acoustic damping compared with a plastic cavity. Eight place settings is honest capacity for the width, with a cup tray on top of the two lower racks.
The cycle list is full for a machine in this class: Heavy, Normal, ECO, Glass, Rapid and Rinse, plus Sanitize, Hi-Temp and Heated Dry options and nine settings on the LED display. A leakage sensor shuts off the water supply automatically, which on an 18-inch install directly under a sink is worth having.
Its published 52 dB rating is the highest in this lineup, and we want to be straight about that. In a closed kitchen it stays out of the way. In an open floor plan with a hard floor, a 52 dB run is audible from the living room, and if you are building this guide around noise alone, the 18-inch format is where the compromises are.
Who should buy the EdgeStar 18-inch?
This is the right call for anyone with a fixed 18-inch opening who wants stainless interior hardware and a broad cycle selection without stepping up in price. In older homes where cabinetry is dated and the goal is a functional replacement rather than a design feature, the value is difficult to argue with.
It also suits households of two to four people who run a full load every day or two. Owners frequently describe it as strong value, and the review volume means the long-term failure patterns are well documented rather than a surprise.
Who should skip it?
Skip it if the cabinet opening is 24 inches and you have the option. At 18 inches you give up a meaningful amount of rack height, and 52 dB is not the quietest number available. If your kitchen is open to a living space, the difference between 52 dB and 45 dB is the difference between audible and forgotten.
Also weigh the one-year warranty against a 93-pound alternative that carries more hardware for your money. This unit is 62.8 pounds, which is light, and the light build shows up in the rack and button feel.
3. Midea 18 Inch Built-In Dishwasher – The Budget 18-Inch Workhorse
Midea 18 Inch Built-in Dishwasher, 8 Place Settings, Stainless Steel Tub
52 dB operation
8 place settings
Stainless steel tub
6 programs, heated dry
54.6 lb
Pros
- Owners report it is barely audible in open kitchens
- Strong cleaning on pots and pans
- Adjustable racks handle items up to 11 inches
- Heated dry reduces the need for towel drying
- Energy Star certified at 15.5 gph
Cons
- Published 52 dB rating
- Cluster of reviews report machines arriving with an E4 fault
- Customer service and repair scheduling draw heavy criticism
Midea’s 18-inch is the value answer in this category, and owners in r/Appliances describe the brand generally as a quiet, good-value option in the budget tier. The machine itself is competent: a stainless steel tub, eight place settings, and a program list of Heavy, Normal, ECO, Delicate, Quick and Rinse with Heated Dry, Hi-Temp and Sanitize on top.
The Hi-Temp cycle holds water at up to 136 degrees F, which is the setting to use for baby bottles and heavily soiled bakeware. Adjustable legs let the racks handle plates, pots and pans up to 11 inches high, and the whole unit is Energy Star certified at 15.5 gallons per hour. At 54.6 pounds it is the lightest full built-in in this roundup, which matters during installation.
Cleaning is where this machine wins its reviews. Owners with heavy loads of pots, pans and baking sheets report strong results, and heated dry performs well enough that towel drying stops being a routine step. Many buyers describe it as a step up from a previous name-brand machine in the same footprint.
The published noise figure is 52 dB, matching the EdgeStar, yet owners describe it as very quiet in practice. That gap between spec sheet and lived experience is the honest headline here: perception depends on cabinet material, flooring and how hard the water is running, and many 18-inch installs sit inside a wood cabinet cavity that absorbs more sound than a spec-sheet lab.
When the Midea 18-inch earns its spot?
It fits buyers who have an 18-inch opening, want stainless interior durability, and need the largest program selection at the lowest end of the built-in market. Families cooking heavily one or two nights a week will get more from it than a small household will, because the 11-inch clearance and Hi-Temp options are built for that.
It is also the pick for a rental or a secondary kitchen where a heavier service call is less of a concern than the upfront cost.
When to look elsewhere?
Be cautious if you cannot tolerate a service call. A meaningful cluster of reviews describes machines arriving with an E4 error code, a leaking water intake valve or a hole in the sump pump housing, and the follow-up experience with Midea support and repair scheduling is one of the most criticized parts of this review set. Budget for a possible repair in the first year.
Also note the 18-inch interior is tight. Some buyers underestimate the capacity before buying, and if you regularly run a full week of dishes for five or more people, a 24-inch body is a better long-term fit.
4. Honeywell 18 Inch Built-In Dishwasher – 42 dB in an 18-Inch Body
Honeywell 18 Inch Dishwasher with 8 Place settings, 6 Washing Programs, Stainless Steel Tub, Built-In Style, UL/Energy Star- White
42 dB operation
8 place settings
Stainless steel tub
6 programs plus 24 hour delay
70 lb
Pros
- Quietest 18-inch built-in in the group
- Owners replaced louder older units for noise
- Simple mechanical push buttons
- ADA compliant dimensions
Cons
- Nylon basket and plastic racks wear faster than stainless
- 18-inch layout means more rearranging
- Only 124 reviews so the record is thin
Forty-two decibels inside an 18-inch body is unusual, and that number alone is the reason this machine is on the list. Multiple owners describe upgrading specifically for lower noise in a small kitchen, a vacation home or a condo, which tells you the gap against a typical 52 dB 18-inch is large enough to notice in daily use.
It is also ADA compliant at 22.6 by 18 by 32.4 inches, which matters for buyers planning a universal-design kitchen. The tub is stainless steel and the machine is UL certified and Energy Star compliant, with a recessed handle and a white finish that suits a laundry-adjacent or utility-room installation.
The program list covers six options: pots and pans, normal, china, quick, rinse only and energy saver, plus a delay start of up to 24 hours that is genuinely useful for running a cycle overnight or during off-peak hours. Eight place settings spread across a top cutlery rack and two lower racks with a removable cutlery basket.
Dishes come out clean and, in several reviews, dry. The push buttons are mechanical rather than capacitive, which means nothing on the panel wears off or fails to respond after a few years of wet fingers.
Where the 42 dB specification pays off?
This is the pick for anyone who has an 18-inch opening and is unwilling to accept 52 dB. In a small kitchen where the dishwasher sits close to a dining table, an apartment with thin walls, or a home where a baby sleeps nearby, ten decibels is a meaningful reduction in how often you notice the machine running.
The 24-hour delay start pairs well with that use case, letting you finish a cycle while you are asleep or out of the house.
What to weigh before buying?
The hardware is not all stainless. The basket is nylon and the racks are plastic, which is the trade-off that keeps the price down and the noise figure low in a compact cavity. Expect to replace racks sooner than you would on a full stainless model, and expect the 18-inch layout to need more load rearranging than a 24-inch machine.
With only 124 reviews, the long-term record is thinner than the group leader’s. One report describes an E4 error and internal water pooling within a month, and another describes a small broken part in the box at delivery. That reads as a modest failure rate rather than a pattern, but it is the kind of thing to check against your return window.
5. KoolMore 24 Inch Panel Ready Dishwasher – 14 Place Settings That Disappear Into Cabinetry
KoolMore 24 in. Panel Ready 14 Place Settings 45 DB Dishwasher in Stainless-Steel, UL and Energy Star Certified (KM-DW2445-PR)
45 dB operation
14 place settings
Panel-ready front
8 cubic feet
93 lb
Pros
- Panel-ready front blends into custom cabinetry
- 45 dB motor suits open kitchens
- Highest place-setting capacity here at 14 settings
- Slide-out racks with pop-up holders
Cons
- Only 16 reviews so long-term reliability is unproven
- Custom panel is not included
- Around a fifth of ratings sit at three stars
The KoolMore is the design pick. A panel-ready front accepts a custom cabinet panel so the machine disappears into a run of cabinetry, which is the single most effective way to make a dishwasher visually quiet in a finished kitchen. It is UL and Energy Star certified, and at 8 cubic feet with 14 place settings it has the highest place-setting capacity of any model here.
The 45 dB motor rating puts it in the middle of the quiet band, and buyers writing about it focus on exactly that: being able to run it in the morning, at night, or in an open kitchen without thinking about it. The slide-out racks move on smooth runners and the holders pop up and pop down, which makes loading tall items in a deep cavity far less awkward than fixed tines.
A pull-out top utensil rack is the detail we would keep if we owned this machine. It takes long spatulas and turners that would otherwise stand upright and block spray arm rotation on the lower racks, a small design decision that saves real frustration in a large cavity.
The drawer itself is rated for six wash cycles and pulls out on a full-extension rail system, so the whole cavity comes to you. That is the point that owners write about repeatedly: there is no deep cavity to reach into and no guessing whether the back row actually got water.
Who this panel-ready machine suits?
It is built for a kitchen where the cabinet run is the design. If you are mid-renovation, matching a panel to existing millwork, or building an integrated kitchen where an exposed stainless door would look out of place, this is the only machine in the roundup that solves it.
The 14 place setting capacity also makes it the best choice for large households, a busy family that runs one load a day, or anyone who hosts regularly and does not want to run a second load.
A recessed pocket handle means no protruding bar to catch a hip in a tight galley run, and the unit measures 24 by 23.9 by 33.9 inches, so it needs a full 24-inch opening with room at the front for the slide-out racks to extend fully.
It is also one of the few machines here designed for a kitchen where the dishwasher should be invisible rather than merely quiet. Buyers who have lived with an exposed stainless door in a finished kitchen describe the panel-ready front as the single feature that made the room feel finished.
What gives us pause?
Sixteen reviews is a very thin evidence base, and roughly a fifth of the ratings sit at three stars, which points to cleaning performance that is acceptable rather than outstanding. Set that expectation and the machine is fine; expect flagship washing and the review pattern does not support it.
Two more practical notes: the custom panel is not included, so the finished look costs extra, and at 93 pounds this is one of the heaviest models here. Both the panel weight and the floor load are worth confirming with your installer.
6. Fisher and Paykel Drawer Dishwasher – 45 dB and a Waist-High Loading Cavity
Fisher Paykel DD24SAX9 24″ Drawers Full Console Dishwasher in Stainless Steel
45 dB operation
Single-drawer cavity
7 place settings
1.81 gallons per cycle
60 lb
Pros
- 45 dB running noise with drawer loading at waist height
- Full console controls are physical and easy to read
- Uses 1.81 gallons per cycle
- Adjustable rack and stainless steel finish
Cons
- 7 place settings is the smallest capacity among the 24-inch models
- Conventional single-cavity format rather than a tall tub
- Only 122 reviews of history
- Not Prime-eligible
The Fisher and Paykel carries a 4.4 average rating, and 76 percent of its reviews are five-star with only 9 percent one-star. The 45 dB figure sits comfortably in the very quiet band, quieter than a typical conversation, and owners writing about it focus on the two attributes the design is built around: noise and the drawer format.
Loading at waist height is a genuine ergonomic advantage. Instead of bending to reach the back of a deep cavity, you pull a single drawer out and load it in front of you, which is easier on your back and faster for smaller households. Full console controls are physical, laid out on the drawer face, and easy to read without being fluent in symbols.
Water use is a real strength. At 1.81 gallons per cycle, this is among the most efficient machines in the group, which is a quiet way to reduce the running cost of the appliance that uses the most water in a kitchen.
The Energy Star rating is worth a second look for anyone who runs the machine daily, because 1.81 gallons per cycle is a fraction of what a hand wash of the same load costs. On a daily run, the water saving over a year is measured in thousands of gallons, and water heating is the expensive part.
At 22.57 by 23.57 by 16.13 inches the unit is a full 24-inch footprint with a drawer-height cavity, which is why it fits under a standard counter without cabinet work. That is unusual for a drawer format, and it means no measurement work before you buy beyond confirming your opening is a full 24 inches.
Because it is a single cavity rather than a full tub, the model is shallow. Loading plates requires standing them at an angle against the rack wall, and tall serving platters are the first thing to prove awkward. Confirm the largest item you wash regularly fits before you commit.
Where the drawer format wins?
The single-cavity drawer is genuinely good for one or two people, a couple, or a second household dishwasher in a home office-adjacent kitchen. When you run one small load a day, you are not leaning into an empty full-size cavity, and the 45 dB rating means the machine can run while you work.
Six wash cycles including a Rapid Wash give you a short option for lightly soiled loads, and the stainless steel finish ages well in a kitchen where the dishwasher is visible.
Where the drawer format costs you?
Seven place settings is the smallest capacity of any 24-inch model here, and that is the honest limit on this pick. A household of four running a single weekly load will feel it. Anyone cooking for a family every day should look at the 12 and 14 place-setting machines instead.
It is also an older conventional format rather than the tall tub most modern buyers now assume, and with 122 reviews the long-term record is shorter than the review leader’s. Budget for the possibility that a future replacement cycle looks different from what you find in stores.
7. Sharp SDW6757ES – 45 dBA With a Third Rack and Interior Lighting
Sharp SDW6757ES 24 in. Top Control Handle 45 dBA Dishwasher
45 dBA operation
Third rack
Heated dry and soil sensors
White LED interior
93.3 lb
Pros
- 45 dBA confirmed by owners who cannot hear it over the refrigerator
- White LED interior lighting and smooth glide rails feel premium
- Third rack takes knives and long serving utensils
- Power Wash zone improves on a basic machine
- Half-load option suits small households
Cons
- Lowest rated 24-inch model here at 3.7
- Reports of a control panel hanging or a delay indicator that will not clear
- Instruction manual does not cover the basics
- Supplied without an electrical cord
- Heated dry does not always finish a load
This is the most interesting machine in the roundup on paper, and the most divided in practice. The specification sheet reads like a machine costing considerably more: 45 dBA operation, a third rack, soil sensors that optimize each cycle automatically, heated dry instead of condensation drying, premium white LED interior lighting and smooth glide rails, all in a stainless tub and basket with stainless racks.
Owners confirm the quiet number in the strongest terms we have heard in this category: the running sound is covered by the refrigerator hum in the same kitchen. If the goal is a dishwasher you genuinely stop hearing, the 45 dBA rating is real.
The half-load feature is the underrated part. It lets a one or two person household run a short cycle without wasting water and energy on an empty cavity, and combined with the soil sensors it means small loads still get a properly adjusted wash.
The Power Wash zone is a dedicated higher-intensity area for heavily soiled items, and reviewers say it leaves dishes noticeably cleaner than a basic machine would.
Why the feature set is worth looking at?
Third racks are the feature most people discover too late. This one takes knives and long serving utensils off the lower racks, which means fewer blocked spray arms and better cleaning on the plates that remain. For a household that cooks with a lot of sheet-pan sized items, the third rack plus Power Wash zone is a meaningful combination.
Water consumption is listed at 3.5 gallons, which is a higher figure than the most efficient models here but normal for a full 24-inch cavity with heated dry.
Why we ranked it lower than the spec sheet suggests?
The rating is the problem. At 3.7 average with 23 percent one-star reviews, this is one of the two lower-rated 24-inch models in the group, and the complaints cluster on the control panel: a panel that hangs or fails to reset, and a delay indicator that never clears. Several owners report machines that would not power on or failed within months.
Two practical notes for installation: the unit is supplied without an electrical cord, so an installation kit is usually needed, and the water and power connections sit at the front of the machine, which complicates hookup compared with a rear-connected unit. The instruction manual is also widely criticized for not covering the basics. If you want the third rack and the lighting, this is the only machine here that delivers both, but budget for a support call.
8. Sharp SDW6726MS – 47 dB With 12 Place Settings and Power Wash
Sharp SDW6726MS 24-inch Stainless Steel Dishwasher, 47 dB Library Quiet, Third Rack, Power Wash Sprayer, 12 Place Settings,
47 dB Library Quiet
12 place settings
Power Wash sprayer
Adjustable third rack
93.3 lb
Pros
- 47 dB Library Quiet operation suits open-concept homes
- Highest-capacity 24-inch model here at 12 place settings
- Three-sprayer Power Wash system for heavy soil
- Adjustable third rack adds loading flexibility
- Fingerprint resistant stainless finish hides smudges
Cons
- Lowest average rating in the roundup at 3.6 with a 21% one-star share
- Plastic basket rather than stainless
- Only 36 reviews
- Same control panel complaints as Sharp's other model
- 1-year limited warranty
The SDW6726MS is a bigger, more capable machine than the Sharp above it, with 12 place settings in a 24-inch body and a three-sprayer system that includes a dedicated Power Wash sprayer. The 47 dB Library Quiet rating sits at the top of the quiet band rather than the very quiet band, which is a real difference of a few decibels from the models above it.
What we like is the combination of the adjustable third rack and the 12 place setting capacity. Nine wash cycles and 20 settings with built-in soil sensors means the machine adjusts automatically, and the third rack takes flatware and serving utensils out of the lower racks so the spray arms keep working.
The fingerprint resistant stainless finish is the quiet practical win. In an open kitchen where the dishwasher face is visible from the living area, smudge resistance keeps it looking clean between cycles, which most buyers notice more often than they expect.
Cutout dimensions are 24 by 34 inches, with a 35 inch maximum, and the product itself measures 23-7/8 by 33-7/8 by 26-15/32 inches, so it is a full-depth 24-inch install. Water consumption is listed at 3.5 gallons per hour.
Nine wash cycles with twenty settings and built-in soil sensors is a deeper cycle list than most machines in this price band offer, and the sensors adjust the cycle automatically rather than making you choose between Heavy and Normal by guesswork. Eco, Heavy, Normal, Rapid and Rinse cover the range, and the twenty settings give you control over options the sensor would otherwise pick for you.
What this machine does better than the smaller Sharp?
Capacity, mostly. Twelve place settings is a real step up from a small cavity, and for a family of three or four that runs daily, the difference shows in how often you need a second load. The three-sprayer layout with a dedicated Power Wash zone is also the better configuration for heavily soiled cookware.
For a larger open kitchen, 47 dB is workable, particularly with a panel or cabinet face in place, and the fingerprint resistant finish keeps the visible surface looking right.
The two Sharp models here share a front-mounted control approach and they draw similar complaints, which is worth knowing if you are weighing the 45 dBA model against this 47 dB one. The one dB difference is small; the rating difference of 3.7 against 3.6 is not meaningful either. Capacity and the third rack are the real separators.
Why we would not put it high on the list?
The rating distribution is the issue: 50 percent five-star, 14 percent four-star, 6 percent three-star, 9 percent two-star and 21 percent one-star. That is a polarized product with a meaningful failure rate, and 36 reviews is a very thin base on which to judge anything.
Negative reviews echo the control panel and reliability complaints described on the other Sharp model in this roundup, so the risk is at the brand support level rather than a single isolated unit. The basket is plastic rather than stainless, the warranty is one year limited, and at 47 dB it is the loudest of the 24-inch models here. If you want the largest quiet 24-inch cavity on a budget, this fills the slot. If you want the fewest support headaches, the 45 dBA Sharp or the EdgeStar is a safer bet.
What Does a Quiet Dishwasher Actually Mean?
A quiet dishwasher is one rated at 44 dB or lower on the manufacturer’s dB(A) scale. That figure means the machine stays below the level of a normal conversation, which is the point in an open kitchen: you should be able to stand at the counter, talk to someone, and not raise your voice. Anything at 45 to 47 dB is still called quiet by most manufacturers, but you will hear it from the adjacent room.
Here is how the ratings break down in practice, using the bands that retailers and the manufacturers themselves use. A dishwasher falls into one band or another, and the band tells you more about your experience than the exact number does.
38 to 40 dBA – near silent. Below a whisper. You have to stand next to the machine to confirm it is running. Only the most heavily engineered machines and some compact models reach this.
41 to 44 dBA – very quiet. Comparable to a refrigerator hum. Audible only from a few feet away, and often masked by normal kitchen sounds.
45 to 47 dBA – quiet. Noticeable during the wash phase in a silent room, but acceptable in most kitchens and apartments.
48 to 50 dBA – noticeable. Clearly audible from the next room. Common in plastic-tub models.
51 dBA and above – loud. Dominant in a quiet house. Fits a closed kitchen, not an open floor plan.
Two real-world sound anchors help more than the numbers do. At 40 dB you are at roughly the level of a whispered conversation, which is why the EUHOMY countertop unit can run during a call. At 52 dB you are around the level of normal speech or steady rainfall on a window, which is why the 18-inch built-ins in this group are fine behind a closed door and obvious in an open plan.
Now the caveat that matters: dBA is an average, not a peak. Every machine in this list has a loud moment, and it is almost always the same one. The drain pump empties at the end of a cycle, and that short burst is frequently what people describe as the dishwasher being loud. The spray arm wash phase is the other noisy stretch, and it is continuous. If a review quote says a machine is loud “at the end,” that is the drain pump, not a failing motor.
Forum owners point out repeatedly that perception is contextual: how loud a dishwasher seems depends on your location, your flooring, and the cabinet it sits inside. The same 45 dBA machine can read as silent under a wood cabinet with a carpeted floor and as intrusive in a tiled kitchen with an island. The spec number is a useful filter, not a verdict.
Which cycle is the loudest, and how to run it quietly?
The wash phase is the loudest part of any cycle, and the reason is simple: water is hitting the tub walls and the dishes continuously for the length of the wash. A Heavy or Baby Care cycle runs that phase longest, so it produces the most total sound even at the same average rating. Heated dry adds a second noisy stretch at the end, because a resistance element working inside a stainless tub is not a silent addition.
Three habits reduce the noise you actually hear. Running the machine during a period when the house is quiet changes perception more than any cycle choice. Choosing Normal or ECO over Heavy cuts the wash phase length and therefore the total sound emitted. And using the delay start several models here offer means the loud phase happens while you are asleep rather than during conversation.
What each quietness tier costs in practice?
Noise does not scale with spending in a straight line, and the tier structure in this category is clear. Entry-level 18-inch built-ins cluster at 52 dB. The mid tier adds tub material, a better control panel and a leakage sensor while staying near the same figure. The step up to 45 dB buys a stainless tub, longer cycles and more rack configuration. The quietest results come from compact no-hookup formats, where there is simply less tub to resonate.
That last point is worth sitting with. A countertop unit at 40 dB beats every built-in in this roundup, and the reason is physical rather than budgetary. If quietness is the only thing that matters to you and your counter has the space, a 40 dB portable format is a legitimate answer that a 24-inch premium built-in cannot match.
How We Picked and Ranked These Dishwashers?
Each model was scored on the same five criteria, in this order of weight: published dB(A) rating, owner reports on real-world perceived noise, drying and cleaning performance from owner reviews, interior hardware and rack configuration, and warranty length relative to the build quality.
Where a model has a thin review record, we say so in its review rather than presenting it as a proven pick, because reliability claims without years of owner data are guesses. The KoolMore panel-ready model and the two Sharp 24-inch machines are the three we flagged this way. We also avoided recommending discontinued models, a recurring failure mode in roundup guides that send buyers looking for hardware that is no longer produced.
Every rating and review count quoted in this guide comes from the verified product listing, and every measurement comes from the manufacturer specification sheet rather than from our own acoustic testing. Where owner experience contradicts the spec sheet, we report both rather than picking the flattering version.
Two products in this roundup carry a rating of 3.7 and 3.6 with a large share of one-star reviews, and one carries only sixteen reviews in total. We kept them in because honest roundups should show the full field, and because a 45 dB rating with a documented control panel failure is a different purchase than a 45 dB rating with a clean record. Read the cons before the pros.
How to Choose a Quiet Dishwasher?
Set your dBA target from the room, not the brand
Decide where the machine will sit before you decide what to buy. A closed kitchen on the ground floor tolerates 50 dB without complaint. An open floor plan with an island needs 44 dB or below. An apartment with a downstairs neighbor, or a home office sharing a wall, needs the same. The cheapest way to avoid a return is to measure the distance from the dishwasher to where you sit or work, then pick a band rather than a model.
Understand what actually makes a dishwasher quiet
Noise comes from three sources: the motor and circulation pump, water spraying from the spray arms, and the drain pump at the end of a cycle. What reduces it is a stainless steel or hybrid tub instead of plastic, multi-layer sound-dampening insulation, rubber-mounted motor components, and anti-vibration feet. That is why an all-stainless 18-inch machine at 52 dB can sound better in a wood cabinet than a plastic-tub machine at 47 dB on a tile floor.
Check the format before the features
An 18-inch built-in is the answer when your cabinet opening is 17.75 inches or narrower, and for small kitchens, condos and apartments. A 24-inch built-in gives you more rack height, larger place-setting capacity, and access to third racks and taller tub designs. A countertop unit wins when plumbing is unavailable or you rent.
Judge drying separately from cleaning
Drying is where quiet machines most often disappoint. Condensation drying relies on residual heat and a cool stainless wall, which is quiet and cheap but can leave droplets. Heated dry adds a resistance element and is louder, though the models in this roundup stay within their published noise rating. Auto-open or auto-vent doors help by releasing steam at the end of a cycle, and they are quiet themselves. Whatever you pick, plan on a short separate dry cycle for plastics, which do not retain heat.
Read the warranty as a reliability signal
Owners on appliance forums ask about longevity more than any other topic, and the answer is that brand support quality varies more than spec sheets suggest. Most units in this group carry a one-year warranty, which means the machine’s real expected life is well beyond any covered period. Look at the interior hardware first: stainless tubs, racks and baskets outlast plastic, and a machine whose reviews are dominated by service complaints is worth skipping even if the dBA number is excellent.
It is worth reading the same kind of noise-focused research we do for quiet tower fans for bedrooms and quiet space heaters, because the same trap applies: a headline figure measured in ideal conditions, and everything else happening in the room.
Match the machine to your household size
Place setting capacity is the number that causes the most returns after purchase, and it is not a lifestyle detail. Seven place settings suits one or two people. Eight settings in an 18-inch body suits two to four. Twelve and 14 setting cavities suit families of four or more who run a load every day. Buying a full-size cavity for two people wastes water and energy on every run; buying a small cavity for a family of five means running twice as often.
Decide between 18-inch and 24-inch before anything else
Measure your cabinet opening first, because it removes every other option. An opening of 17.75 inches or narrower means an 18-inch slimline, and within that size the Honeywell at 42 dB is the quietest option in this guide. If you have a 24-inch opening, you gain rack height, capacity and access to third racks, and the field of choices opens up at 45 to 47 dB.
For apartments, both routes work. Renters with a compact kitchen or no plumbing are best served by the no-hookup format. Owners of a condo with a standard 18-inch cabinet opening get the most from the 42 dB slimline, because ten decibels below the usual 52 dB slimline is the single largest noise improvement available at that width.
Know what you give up at each step up
Every quiet dishwasher in this roundup trades something. The no-hookup format gives up capacity. The 18-inch slimline gives up rack height. The 24-inch models give up warranty length, since most carry a single year. The panel-ready machine gives up an included custom panel and a proven service record.
Deciding which trade you can live with is faster than trying to find a machine that has everything, because in this category it does not exist. Write down your non-negotiable first, usually either a specific cabinet opening or a noise ceiling, and let the rest be a preference rather than a requirement.
How to Make an Installed Dishwasher Quieter?
Before blaming the machine, work through these five steps. Most of the difference between a 45 dBA dishwasher that is intrusive and one that is invisible comes from installation.
Fit an anti-vibration pad under the unit. A closed-cell foam isolation pad between the dishwasher feet and the subfloor cuts the low-frequency thud that carries through hard surfaces. This is the single highest-impact change.
Use the isolation bracket. Built-in dishwashers bolt to the cabinet frame through a bracket that decouples the tub from the cabinet walls. Skipping it, or overtightening the bolts, defeats the entire design.
Level the legs properly. An off-level machine rocks under load, and a rocking tub produces a knocking sound no decibel rating accounts for.
Confirm the door seal and latch. A door that does not latch fully leaks sound and water, and many of the loud complaints trace back to a seal that needs replacing rather than a pump that needs repair.
Use delay start for the noisiest cycles. Running the machine overnight or while the house is empty removes the noise from the hours when it is least welcome, and several models here offer a delay start of up to 24 hours.
Frequently Asked Questions
What brand of dishwasher is the quietest?
Among the models we reviewed, the quietest rating belongs to the EUHOMY countertop dishwasher at 40 dB, a no-hookup unit that runs off a 5-liter tank. Among full built-ins, the Honeywell 18-inch model is the quietest at 42 dB, followed by a cluster of 45 dB machines from KoolMore, Fisher and Paykel and Sharp. Bosch is widely cited as the quietest brand overall, though its premium 800 Series units sit well above the price tier of everything in this roundup.
Which dishwasher has the lowest decibels?
The lowest published decibel rating in this roundup is 40 dB, from the EUHOMY portable countertop dishwasher. The quietest built-in model here is the Honeywell 18-inch unit at 42 dB. Five models cluster in the 45 dB range, and two 18-inch built-ins sit at 52 dB, which is the loudest figure in the group. Remember that dBA is an average, and the drain pump spike at the end of every cycle is louder than the average suggests.
Is 44 decibels quiet for a dishwasher?
Yes. A dishwasher rated at 44 dBA operates below the level of normal conversation, which is the practical threshold for a quiet machine. Anything from 38 to 44 dBA is generally considered very quiet, and you should be able to talk at the counter without raising your voice. At 45 dB and above you will start to notice the wash phase in a silent room, and by 51 dB the machine is clearly audible from the next room.
What is the quietest most reliable dishwasher?
The EUHOMY countertop dishwasher pairs the quietest rating in the group at 40 dB with the highest review volume at 1015 ratings and a 4.5 average, which is the strongest evidence of durability in this lineup. Among built-ins, the EdgeStar 18-inch model has 844 reviews at 4.2 stars, all-stainless tub, racks and basket, and a documented service history rather than a thin one. For 24-inch capacity and quiet operation together, the Sharp SDW6757ES scores well on features but poorly on its 3.7 rating.
What brand of dishwasher has the least problems?
Review patterns in this roundup favor models with stainless interior hardware and high review volume. The EdgeStar 18-inch and the EUHOMY countertop unit both draw a large share of long-term owner reports with consistent results. Midea draws praise for quiet, good-value performance but also a documented cluster of units arriving with an E4 fault or a leaking intake valve, and both Sharp models carry repeated control panel complaints. Check the current review page before buying, because failure patterns change between model years.
What dishwasher should I stay away from?
In this roundup, we would avoid the Sharp SDW6726MS, which carries the lowest average rating at 3.6 with a 21 percent one-star share on only 36 reviews, and the Sharp SDW6757ES at 3.7 with 23 percent one-star. Both share control panel complaints about hanging panels, delay indicators that will not clear and machines failing within months. We would also think twice about the Midea 18-inch if you cannot tolerate a service call, because warranty repair scheduling is heavily criticized by affected owners.
The Verdict: Which Quiet Dishwasher Should You Buy?
The best quiet dishwashers in 2026 are not one machine, they are three depending on your cabinet. If noise is your only priority and you need no plumbing, the EUHOMY countertop unit at 40 dB wins on both the quietest number in the group and the deepest owner history here. If you have a fixed 18-inch opening, the Honeywell at 42 dB is the quietest built-in you can buy, and the EdgeStar is the proven, all-stainless value pick with 844 reviews behind it. If you need 24-inch capacity, the 45 dBA Sharp SDW6757ES has the best feature set but the weakest reliability record, so buy it for the third rack and accept a possible service call.
Whichever you choose, install it properly. An isolation pad and a correctly torqued bracket will do more for real-world noise than a three-decibel difference between models. We also compared noise-first appliances in the same vein for quiet massage guns for home use, and the same rule holds: the number narrows the field, the room decides the winner.
