If you are hunting for the best quiet dishwashers for open kitchens, start with the number on the spec sheet: anything rated at 45 dBA or below can run through a full cycle while you talk across a kitchen island without either of you raising your voice. The six machines below all publish their operating sound level, and every one of them falls in a narrow 42 dBA to 52 dBA band.
That range matters more than usual in an open-concept home. A closed kitchen has walls that swallow most of a dishwasher’s pump and drain noise before it reaches you. An open kitchen has none of that softening, so hard floors, a stone island and a full-height cabinet bank can carry every rattle straight into the living room. The right machine for that room is the one whose published rating is low and whose tub, door seal and mountings keep the vibration from turning into rattle.
We compared six built-in models across published dBA, tub material, capacity, cycle options, warranty length and what owners actually say about noise in their own kitchens. Our criteria, in short: the dBA rating came first, then the construction that backs the number up, then the volume of verified owner feedback behind the claim. Every model here is a genuine built-in unit, not a portable or countertop machine pretending to be one.
Top 3 Best Quiet Dishwashers for Open Kitchens (October 2026)
Honeywell 18 Inch Built-in Dishwasher
- 42 dB
- 8 place settings
- Stainless steel tub
- Delay start
Two of those three are 18-inch slimline bodies rather than full 24-inch cabinets, and that is not a compromise we hid. In most open kitchens the dishwasher is tucked beside an island or under a counter run, and a machine that leaves 6 inches of unused cabinet is 6 inches of usable storage given away. Where capacity does matter more than cabinet width, the 24-inch models at picks 3 and 5 cover that.

Sort that table by dBA and the shape of the set becomes clear. The lowest published rating here is 42 dBA and the highest is 52 dBA, with three picks clustered between them at 45 to 47 dBA. A 10 dBA gap is roughly half as loud again, so the difference between a 42 dBA machine and a 52 dBA machine is not a small one at 10 o’clock at night.
What dBA Actually Means in an Open Kitchen
dBA is a weighted decibel reading that tracks how loud something sounds to a human ear, not how much energy it puts out. Because the scale is logarithmic, a 3 dBA difference is noticeable and a 10 dBA difference sounds like half the volume.
For context in a domestic room, a quiet library sits near 40 dBA, an unhurried conversation runs around 50 dBA, and a garbage disposal is closer to 65 dBA. That is why appliance makers target the low 40s for premium models: a dishwasher at 44 dBA sits underneath speech rather than competing with it.
The band list below is how I read the numbers on a spec sheet, and it is the same framework I used to rank the six picks.
38 to 41 dBA – below a quiet library. Effectively inaudible in an open kitchen from more than a few feet away.
42 to 44 dBA – the sweet spot for open plans. You notice it if you are listening for it and forget it otherwise.
45 to 49 dBA – acceptable beside an island, noticeable during the drain and drying phase from the living room side.
50 to 54 dBA – fine behind a closed door, obvious in an open room. Best reserved for closed kitchens or daytime-only runs.
55 dBA and above – the machine becomes part of the conversation. Not a fit for an open kitchen.
One caution about the whole exercise: the printed dBA is an average across a cycle, not a ceiling. The drain pump, the spray arm and the drying phase each peak above the headline figure, and I come back to that below.
How We Evaluated These Six Dishwashers
Every appliance roundup on this topic starts with the same complaint from owners, and it is a fair one: the published number does not always match the lived experience. So our ranking weights four things in this order.
Published dBA came first, because it is the only figure a manufacturer commits to in writing and the only one you can compare across brands. Tub and construction material came second, since a stainless steel interior damps vibration better than plastic and is the single best predictor of whether a quiet rating holds up over time. Rack rollers, door seal and mountings came third, because those determine how much of that sound turns into vibration in your cabinetry. Owner feedback volume and warranty length came last, and they matter for a different reason: they tell you whether the machine is likely to still be quiet in year eight.
Every product below lists its manufacturer or retailer rating and the number of verified owner reviews behind it, copied exactly as published. We did not estimate any of those numbers, and we did not repeat any specification that the manufacturer does not publish.
1. Midea 18 Inch Built-in Dishwasher – Best Overall Pick
Midea 18 Inch Built-in Dishwasher, 8 Place Settings, Stainless Steel Tub
52 dB operation
8 place settings
Stainless steel tub
Energy Star certified
Pros
- Largest body of verified owner feedback in this group
- Cleaning holds up across load types
- Handles large pots and pans in an 18-inch body
- Simple installation into an existing cabinet opening
Cons
- 52 dB is quieter than standard but not among the very quietest
- Service and repair scheduling reported as slow by some buyers
- Some units arrived with a defective sump pump housing
- Leg-mounting instructions are thin
The Midea 18 Inch Built-in Dishwasher publishes a 52 dBA operating sound level, which puts it mid-pack acoustically and ahead of the pack on evidence. It carries 551 verified owner reviews, more than the other five machines combined by a wide margin, so the noise behaviour described here is not a single reviewer’s impression.
What that owner base consistently describes is a machine that stays near the background during the wash itself, with a short pump hum at the start and again at the end when the machine fills and drains. That is the shape of noise you can live with in an open kitchen, because the loud middle section of the cycle is where most dishwashers earn their reputation and this one keeps it low.
The body is 22.6 inches deep, 17.6 inches wide and 32.4 inches high, with adjustable legs, and it holds 8 place settings in a stainless steel tub. Owners note that it takes large pots, pans and bakeware despite the slim footprint, which is a genuine advantage when your cookware does not shrink to fit a narrow cabinet.
Program choices cover Heavy, Normal, Eco, Delicate, Quick and Rinse, plus three functions: Heated Dry, Hi-Temp and Sanitize. The heated dry runs on every cycle except Rapid and Self-Clean, and the Hi-Temp function holds the water at up to 136 F, which is the number to care about if you run bottles or a toddler’s plateware through the machine. It is Energy Star certified and draws 15.5 gallons per hour at the cycle’s peak use.
Who this dishwasher suits
This is the pick for a small or galley kitchen where cabinet width is the constraint and you still want a stainless tub and a heated dry. It is also the safest recommendation in the set from a support standpoint, purely because 551 reviews means 551 data points on how the machine holds up after a year or two.
Owners comparing it to larger name-brand machines report being surprised by the cleaning performance, and the 8-place-setting interior handles everyday family loads without the pre-rinsing that a compact machine often demands.
Where it falls short
The honest limitation is the dBA figure itself. At 52 dBA this is not the quietest number on the sheet, and in a wide-open kitchen with hard flooring you will hear the drain phase. If your kitchen is fully open to a living room and you run dishes in the evening, the Honeywell at pick 2 makes more sense acoustically.
Support is the other weak point. A share of one-star reviews describe E4 error codes traced to a defective sump pump housing on delivery, and the reports of slow repair scheduling and slow refunds are the most common complaint theme. The warranty is 1 year manufacturer, which is the shortest standard length you will see in this group.
2. Honeywell 18 Inch Built-in Dishwasher – Lowest Rated Noise in the Set
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
ADA-compliant body
Pros
- Lowest published noise rating in the group at 42 dB
- Fits a standard 18-inch cabinet opening
- Cleans and dries everyday loads well
- Push-button controls with no lettering to wear off
Cons
- Only a 1-year limited warranty
- Plastic racks feel less substantial than stainless alternatives
- Interior is shallower than a 24-inch tub
- One report of an internal leak and E4 fault
The Honeywell 18 Inch Built-in Dishwasher is rated at 42 dB, the lowest published operating sound level of any model in this roundup, and it is the one I would put in a genuinely open kitchen before anything else on this list. It holds 124 verified owner reviews at a 4.2 average, and quietness at that rating is the single most common theme in the feedback.
What owners describe is a machine they can forget is running. The 42 dBA figure sits under ordinary conversational volume, which means a load can go in during dinner service and the pump noise does not compete with people talking at the table.
The cabinet is 18 inches wide and 32.4 inches high with a 22.6 inch depth, and the listing marks it ADA-compliant, so it suits a retrofit where accessibility clearance is the deciding factor. Inside there are 8 place settings with a top cutlery rack, two lower racks and a large removable cutlery basket, all on a stainless steel tub.
Six washing programs cover pots and pans, normal wash, china, quick wash, rinse only and an energy saver mode, and there is a delay start of up to 24 hours. That delay timer is worth more in an open kitchen than most buyers expect, because it lets you run the machine at 2 a.m. or mid-morning rather than during the evening wind-down.
Who this dishwasher suits
This is the pick for an apartment or condo with an existing 18-inch opening and thin walls, where the neighbouring room is close and 42 dB is the difference between ignoring the machine and hearing every cycle. It is also the sensible choice for anyone who works from home and does not want an audible appliance interrupting calls.
Owners installing into an existing 18-inch cabinet opening call the install straightforward, and the recessed handle leaves the front clean without a protruding bar to catch.
Where it falls short
The reliability picture is thinner than the noise picture. With 124 reviews there is less long-term data behind this machine than behind the Midea, and at least one owner reports an internal leak with an E4 error code inside the first month. That is a single report rather than a pattern, but it is worth knowing before you commit.
The 1-year limited warranty is the other gap. On a machine this quiet you are likely to keep it a long time, and a 1-year term means the pump, the drain motor and the door seal are all exposed after twelve months. The racks are plastic and the basket is nylon, which also means more rattle potential against the tub than stainless rolling racks.
3. Sharp SDW6726MS 24-inch Dishwasher – Best for Larger Loads
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
Adjustable third rack
Front touch control
Pros
- 12 place settings in a standard 24-inch body
- Adjustable third rack for flatware and serving utensils
- Power Wash sprayer and soil sensors handle varied soil
- Low 3.5 gallon per hour water use is efficient
- Fingerprint-resistant stainless finish
Cons
- Lowest average rating here at 3.6 with 21% one-star reviews
- Front touch controls are hard to use with wet hands
- Reports of delivery and installation damage
- Needs a precise 24 by 34 inch cutout
The Sharp SDW6726MS publishes 47 dB under Sharp’s Library Quiet label, which is a legitimate open-kitchen rating once you know where the threshold sits. It is the first 24-inch machine on this list, holds 12 place settings, and at 3.6 from 36 reviews it is also the model with the thinnest owner evidence here, so read the section on where it falls short before you commit.
Forty-seven decibels lands in the acceptable-for-an-island band. In practice that means you will hear it running when the kitchen goes quiet, and you will not hear it over a conversation or a television in the next room.
The adjustable third rack is the feature that separates this from the compact models. It slides to make room for tall items below, and it takes flatware and serving utensils above, which on a 12-place-setting interior matters more than it would on an 8-place-setting one. Metal racks, a plastic cutlery basket and a three-sprayer system with a dedicated Power Wash sprayer round out the wash hardware.
Soil sensors adjust the wash automatically, so the machine picks its own cycle length rather than running you through a menu. There are 5 wash cycles and 4 options, front touch controls, 20 settings, and a fingerprint-resistant stainless finish that keeps the front from showing every handprint in a room where the appliance is on display. It is Energy Star certified and uses 3.5 gallons per hour.
Who this dishwasher suits
This is the pick for a household that actually runs out of space in an 8-place-setting machine, particularly one that uses serving platters and a lot of cookware. The 12-place-setting interior and the adjustable third rack handle a full dinner-party load without a second run.
It is also the right call if you are replacing into a standard 24-inch opening and want a third rack without moving to a premium brand. Just measure the cutout first: the listing calls for 24 by 34 inches, 35 at maximum, with a depth of 24 inches.
Where it falls short
The 3.6 average is the lowest in this roundup, and 21 percent of reviews are one-star. The dominant negative theme is not noise or cleaning, which reviewers rate well on paper, but logistics: delivery and installation damage, and a small number of units needing service within the first months of ownership. At 93.3 pounds, this is a heavy appliance to receive badly.
Front touch controls are the other recurring complaint. Wet hands do not register reliably on capacitive panels, and a control you have to dry your hands to use is a small daily irritation in a kitchen where your hands are wet most of the time. The warranty is 1 year limited, again the shortest term here.
4. COMFEE 18 Inch Built-in Dishwasher – Best for Sanitizing Cycles
COMFEE’ 18 Inch Built-in Dishwasher, Energy Star & NSF, Stainless Steel Tub
52 dB operation
8 place settings
NSF certified sanitize
Adjustable upper rack
Pros
- NSF certification and a sanitize function owners rate highly
- Adjustable upper rack moves for tall glasses and pots
- Quiet 52 dBA relative to older compact machines
- Heated dry works better than expected
- Stainless tub feels premium
Cons
- Power cord not included
- Non-standard width so measure the opening first
- Water supply connection can leak at the front
- Rack adjustments are thinly explained in the instructions
The COMFEE 18 Inch Built-in Dishwasher publishes 52 dBA and holds 4.2 across 24 verified owner reviews. The number is the same as the Midea’s, and the shared advantage is that both are noticeably quieter than the compact dishwashers most people are replacing, particularly an older unit that still rattles like a paint mixer.
What separates this machine is the certification. It carries both NSF and Energy Star marks, and the Hi-Temp function holds water at up to 136 F for bottles and children’s dinnerware, which is the reason to consider it if your household is doing a lot of baby items or sports gear.
The upper rack adjusts upward by 1.97 inches, which is enough clearance for tall wine glasses and stock pots without taking the whole rack out. The lower rack takes plates up to 13.78 inches, so a full-size dinner plate fits flat. Six wash cycles cover Heavy, Normal, Eco, Delicate, Quick and Rinse, with Heated Dry, Hi-Temp and Sanitize functions, and there is a 1 to 24 hour delay plus a one-hour quick wash for a fast top-up before guests arrive.
Cabinet dimensions match the Midea at 22.6 by 17.6 by 32.4 inches, and the machine weighs 54.7 pounds, which makes it a two-person lift. The stainless tub is the part that helps noise over time, since a plastic tub amplifies the pump noise that a steel one absorbs.
Who this dishwasher suits
Households that care about sanitization rather than decibels: families with a baby, anyone running sports equipment or garden produce through a cycle, and small kitchens where the NSF mark is on a shortlist for a reason no other compact machine here can claim. It is Energy Star certified, so the running cost side is covered too.
Owners report that the heated dry performs better than expected at this size, and the delay timer plus one-hour quick wash makes it flexible for a kitchen where you run small loads often.
Where it falls short
Two practical items will trip people up. The power cord is not included, so you are buying one in your first hour, and the width is not the standard 24 inches, which means an existing cabinet opening has to be measured before the delivery driver arrives.
Owners also flag that the water supply connection can leak at the front if it is not sealed properly, and that the instructions explain the upper rack adjustment thinly. Plastic items can retain a few drops of water after a cycle even with heated dry, and the warranty is 1 year manufacturer.
5. KoolMore 24 in. Panel Ready Dishwasher – Best Panel-Ready Pick
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
Stainless tub
Pros
- 45 dBA is among the quietest ratings here
- Panel-ready front disappears into cabinetry
- 14 place settings is the largest capacity in this group
- Pop-up and pop-down rack holders aid loading
- Energy Star and UL certified
Cons
- Custom cabinet panel not included
- Only 16 ratings gives limited long-term data
- Listing copy refers to an 18-inch dishwasher in one bullet
- Sits well above the compact models
The KoolMore 24 in. Panel Ready Dishwasher publishes 45 dB and holds 14 place settings, the largest interior of the six here. It is the only model on this list designed to disappear into cabinetry, which is a visual decision as much as an acoustic one for a kitchen where the dishwasher faces a living room.
Forty-five decibels sits in the band you want for an island installation. Paired with a matching cabinet panel, the machine also stops being a visual distraction, and the panel itself adds a layer of mass at the front of the door that many owners find takes the edge off the sound.
Loading is the quiet strength. Two ergonomic racks slide out, and the holders pop up and pop down so you can change the configuration for a tall pot one day and a sheet-pan run the next. A pull-out top rack takes long spatulas, spoons and turners, which is the space-saving answer to a third rack in a shallow cabinet.
Controls are low-profile touch with an LED display, the handle is a recessed pocket style, and the tub and finish are stainless steel. It carries UL and Energy Star certification and comes with a 1-year parts and labor warranty. The body measures 24 inches deep by 23.9 wide by 33.9 high and weighs 93 pounds.
Who this dishwasher suits
A remodel where the dishwasher is front and centre under an island, and where the cabinetmaker is supplying the custom panel. The 14 place setting capacity also makes it the pick for a family that cooks big on Sundays and does not want to split a load across two cycles.
Owners highlight the 45 dBA rating and the hide-it-in-your-cabinetry design together, and the rating distribution is unusually top-heavy with no one-star reviews in the sample. Treat that cautiously though, because the sample is 16 ratings.
Where it falls short
The custom panel is not included, so the total cost of the finished look is higher than the machine alone and depends on your cabinetmaker. That is a real step for a buyer who has not already decided on panel-ready cabinetry.
The 16-review base is the bigger issue. There is not enough long-term data here to make claims about how this machine sounds after five years, and the listing copy is inconsistent enough that one feature bullet describes an 18-inch dishwasher on a 24-inch product page. If quietness is your primary requirement and support matters, this is a purchase to buy with your eyes open.
6. Fisher Paykel DD24SAX9 Drawer Dishwasher – Highest Owner Rating
Fisher Paykel DD24SAX9 24″ Drawers Full Console Dishwasher in Stainless Steel
45 dB operation
7 place settings
Single-drawer loading
Full console controls
Pros
- Highest average rating here at 4.4 with a strong share of five-star reviews
- Drawer format loads and unloads at waist height
- Full console gives dedicated controls instead of hidden menus
- Uses 1.81 gallons per cycle
- 45 dBA is quiet enough to run while entertaining
Cons
- Only 7 place settings
- the smallest capacity among the 24-inch models
- Full console takes counter space above the machine
- Fewer features such as no third rack or panel-ready front
- Premium pricing for the capacity
The Fisher Paykel DD24SAX9 publishes 45 dB and holds 4.4 from 122 verified owner reviews, the highest average rating of the six here. Where the Midea leads on volume of evidence, this machine leads on satisfaction, and the drawer format is the reason most of its owners come back to it.
Instead of a hinged door that drops down and forces you to bend and reach into a tub at floor level, this is a single drawer that slides out. Loading and unloading happen at waist height, which is also the reason it stays quiet in practice: a full-height door swinging open and racks rattling is a noise source people rarely account for when they read a dBA figure.
Full console controls sit on the fascia rather than being buried behind a menu, so every setting has a physical control and nothing needs to be remembered between cycles. There are 6 cycles including a Rapid Wash, an adjustable rack, and an ENERGY STAR rating with water consumption listed at 1.81 gallons per cycle, which is the lowest water figure of any machine here.
The body measures 22.57 inches deep by 23.57 wide by 16.13 high and weighs 60 pounds, so it is a lighter install than the other 24-inch models on this list. The stainless steel finish and integrated styling are designed to sit under a counter run without dominating it.
Who this dishwasher suits
A couple, a single-person household, or anyone with a back or knee issue who finds a hinged door hard work. Seven place settings suits one or two people comfortably, and owners consistently treat that as the right size rather than a compromise.
It is also a good fit for a kitchen where the dishwasher faces a living room and you run it while people are over, because 45 dBA is described by owners as quiet enough to talk through.
Where it falls short
Capacity is the real limit. Seven place settings is the smallest interior of the 24-inch models here, so a family of four doing a full dinner load will run the machine twice where the KoolMore’s 14 settings would do it once.
The full console takes up counter space above the machine, and there is no third rack and no panel-ready front, so it does not solve the visual problem the way the KoolMore does. The warranty is 1 year.
What Actually Makes a Dishwasher Quiet?
Noise control in a dishwasher comes down to four things, and you can usually see all four in the specification sheet before you buy.
Layered sound insulation. The tub is wrapped in sound-dampening material, and the quality and thickness of that wrap separates a 42 dBA machine from a 52 dBA one more than any other single feature.
Stainless steel tub. A steel tub damps vibration better than plastic and does not amplify the pump the way a plastic shell does. Every machine in this roundup has a stainless interior, which is why noise differences here are narrower than the dBA spread suggests.
Motor and mount construction. An inverter drive motor ramps speed smoothly instead of surging, and anti-vibration mounts between the tub and the cabinet frame stop vibration transferring into your cabinetry. This is also the single biggest reason a 24-inch model often sounds deeper than a slimline: more steel, more mass, more insulation.
Door seal and rack hardware. A tight gasket around the door and ball-bearing rack rollers keep glassware and tines from clattering, which is the noise you hear as rattle rather than hum.
Why the Published dBA Is Not the Whole Story
A dBA figure is an average across an entire cycle, and the phases inside a cycle are not equally quiet. Knowing which part is loudest tells you what you will actually hear, and when.
The fill is short and quiet. The water inlet valve runs for a minute or two and is rarely the problem.
The wash is the steady baseline. Spray arms spinning and water hitting dishes is the level the published number mostly reflects, and it stays close to the headline figure for most of the cycle.
The drain is usually the loudest moment. The drain pump pushes several gallons through the sump at high flow, and this is where a 44 dBA machine most obviously departs from its rating. It lasts 30 to 60 seconds and it is the phase owners describe first when they say a dishwasher is too loud.
Drying can be louder than washing. Any heated dry or fan-assisted system adds sound at the end of the cycle, sometimes at a frequency people find more irritating than the wash even when the volume is similar. Condensation drying systems are the quietest option here.
Two further factors sit outside the machine. Aging spray arms and worn bearings get louder before the pump does, and hard floors such as tile, stone and polished concrete amplify transmitted vibration in a way carpet and wood do not.
Dishwashers and Setups Worth Walking Away From
Owners searching for dishwasher brands to avoid tend to name patterns rather than one brand, and the same four patterns show up repeatedly in forum threads and review data.
The cheapest model inside an otherwise quiet brand. A brand known for 40 dBA machines also sells a loud one. The entry tier is where the insulation wrap and the motor get cut, and that machine will not match the brand’s reputation.
Units without a stainless tub. Plastic tubs transmit pump noise directly and get louder as they age. In an open kitchen this single specification can move a machine a full band.
Slimline and condenser models bought for capacity reasons. Compact 18-inch machines are consistently perceived as noisier than their 24-inch counterparts, because there is less steel and less insulation in the same footprint. The 18-inch picks here are the exception rather than the rule, and they earn their place on dBA rather than on size class.
Anything without a delay start, in an open kitchen. This is a setup mistake more than a product mistake. A machine that must run in the evening is a problem in a way the same machine running at 2 a.m. is not.
On installation, the two things that most often cause a machine to be replaced for noise are an unprotected drain hose routed so it knocks against the cabinet frame, and legs that are not shimmed level. Both are fixable in an afternoon, and both make a quiet dishwasher sound like a loud one.
How to Choose the Quietest Dishwasher for Your Space
Match the number to the room, not to the brand. A closed kitchen with a door tolerates 50 dBA. A kitchen open to a living room across tile needs 45 dBA or below. A kitchen island facing a TV room with no wall between them is where 42 dBA earns its money.
Then decide between 18-inch and 24-inch. The slimline bodies here are 17.6 and 18 inches wide, which frees roughly 6 inches of cabinet but holds 8 place settings. The 24-inch models on this list hold 12 to 14. If you cook for four or more most nights, capacity wins; if you are a couple or a single household, the slimline is the more sensible footprint.
Check the tub material before anything else, then the warranty. A 1-year warranty appears on every machine in this roundup, so that is not a differentiator here. What does differentiate them is published dBA, tub material, and whether the machine has a delay start.
Consider panel-ready if the dishwasher faces the living space, and consider the drawer format if the hinged door is a physical strain. Loading ergonomics matter more than most spec sheets admit, because a machine you load comfortably is one you stop overfilling, and an overfilled machine is a louder machine.
Finally, measure the opening. All three slimline units here are narrower than the standard 24 inches, and the 24-inch Sharp needs a precise 24 by 34 inch cutout, up to 35 at maximum. Getting this wrong is the most common reason a quiet dishwasher ends up returned.
Five Installation Moves That Cut Dishwasher Noise
Most of the perceived noise in an open kitchen is transmitted vibration, not airborne sound, and vibration responds to installation. Our quiet dehumidifier guide for bedrooms covers the same principle for a different appliance: the machine is rarely the whole problem.
Add an anti-vibration pad under the machine. A closed-cell foam or rubber mat between the feet and the cabinet base cuts the low-frequency thump that carries through a kitchen island.
Deaden the cabinet. Applying an acoustic mat or thick insulation to the underside of the countertop above the dishwasher reduces the hollow drum effect, which is what makes an open kitchen amplify what a closed one absorbs.
Isolate the drain hose. A high loop routed through a hold-down bracket, away from the cabinet frame, removes the knocking that owners most often mistake for a failing pump.
Level and shim the legs. An uneven machine rocks under a full tub, and rocking is a low-frequency noise that a dBA rating does not capture. Check level after the tub is full of dishes.
Schedule the cycle off-peak. Every machine with a delay start here, from the 24-hour Honeywell to the 1 to 24 hour COMFEE, lets you run the dishwasher while the kitchen is empty. In an open plan this single habit does more for perceived quietness than four decibels of rating.
Frequently Asked Questions
What is a quiet level for a dishwasher?
A dishwasher rated at 44 dBA or below is quiet enough for an open kitchen. That is roughly the level of a quiet library and it sits under normal conversation volume, so you can talk across an island without competing with the machine. Ratings of 45 to 47 dBA work beside an island but are noticeable in the drain phase from the next room. Anything above 50 dBA is better suited to a closed kitchen.
What is the quietest dishwasher in this roundup?
The Honeywell 18 Inch Built-in Dishwasher publishes the lowest operating sound level here at 42 dB, with a stainless steel tub and 8 place settings, and it carries 124 verified owner reviews at a 4.2 average. The KoolMore 24 in. Panel Ready Dishwasher and the Fisher Paykel DD24SAX9 follow at 45 dB, while the Midea and COMFEE units publish 52 dB and suit compact kitchens more than open plans.
Are Miele and Bosch dishwashers quieter than these models?
Generally yes on published figures. Bosch models in particular commonly publish operating sound levels in the high 30s to low 40s, and Miele starts around 42 dBA, which is quieter than the 52 dBA compact models on this list. Those brands were not part of this roundup, so treat the comparison as a guide rather than a tested result and check the current specification on the exact model.
Does a third rack make a dishwasher louder?
Owners are split and the honest answer is that it depends on the machine. A third rack adds height, which can mean more water volume in motion and a spray arm closer to the glassware, so some models are audibly higher. The Sharp SDW6726MS pairs an adjustable third rack with a 47 dBA rating, which shows the two are not mutually exclusive. Loading less per cycle also keeps noise down, so treat capacity as part of the answer.
How do I make a dishwasher quieter in an open kitchen?
Start with the cycle schedule. Using the delay start to run the machine while the kitchen is empty removes the problem entirely. Then address vibration, which is what an open kitchen amplifies: add an anti-vibration pad under the machine, insulate the underside of the countertop above it, secure the drain hose on a high loop away from the cabinet frame, and confirm the legs are level. Maintenance matters too, because a worn spray arm bearing or a clogged filter is audible before it is visible.
The Quiet Dishwasher Verdict for 2026
For a genuinely open kitchen, the Honeywell 18 Inch Built-in Dishwasher takes the noise crown on the numbers at 42 dBA, and it fits a standard 18-inch opening. The Fisher Paykel DD24SAX9 matches that quietness with a 45 dBA rating, the highest owner rating in the set, and a drawer format that removes bending from the job entirely.
For most buyers the Midea 18 Inch is the pick, because 551 verified reviews and a 4.1 average tell a far more reliable story than any other machine here, and its 8-place-setting stainless tub handles real cookware in a narrow cabinet. Reach for the KoolMore when the dishwasher is on display and capacity matters, and consider the Sharp or COMFEE when sanitization or a third rack is the priority.
Whichever one you choose, run it on a delay timer and pad the base. Those two habits do more for an open kitchen than the gap between two models on this list. If you want more guidance on keeping background appliances civil in shared spaces, our quiet dehumidifier picks for bedrooms cover the same principles in a bedroom context.
