No one buys a dishwasher hoping to hear it churn through a cycle. The noise level, measured in decibels (dBA), defines the daily experience of the appliance — turning a kitchen into a conversation-friendly space versus a room where you must pause the machine to hear someone speak. For buyers focused on finding the quietest machine that still delivers sparkling results, the search narrows to models rated 50 dBA and below, where the hum blends into background ambient noise.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent countless hours cross-referencing manufacturer noise ratings, analyzing owner-reported reliability data, and comparing wash system architectures across dozens of built-in and portable dishwasher models to identify which ones truly deliver silent, effective cleaning without hidden trade-offs in drying performance or rack design.
This guide examines the most promising quiet-rated dishwashers on the market today, weighing factors like spray arm configuration, drying technology, and real-world noise complaints against advertised dBA figures. You will leave equipped to pick a genuinely quiet machine for your home with the and quietest dishwasher rankings below.
How To Choose The Quietest Dishwasher
Choosing the quietest dishwasher starts with understanding that the dBA rating is not a marketing gimmick — it is an ISO-standardized measurement of sound pressure at a specific distance. However, real-world noise perception also depends on how the machine is installed, the material of the kitchen cabinetry, and whether the model uses a direct-drive motor versus a belt-driven one. Below are the critical levers to pull.
Decibel Floor: What 42 dBA vs. 52 dBA Actually Sounds Like
A drop from 52 dBA to 42 dBA does not seem large on paper, but decibels are logarithmic — a 10 dBA reduction represents roughly half the perceived loudness. Models at 49–52 dBA are generally audible from the next room, while models at 42–45 dBA become essentially silent unless you stand directly in front of the machine. For open-plan kitchens where the dishwasher sits near the dining or living area, prioritize models rated at or below 45 dBA.
Spray Arm Count and Wash Coverage
Quiet machines still need to clean. Three-spray-arm configurations (lower, middle, upper) provide the most complete coverage, but the difference between two- and three-arm setups is most noticeable in the corners of the top rack. Look for models with a dedicated third-level spray arm if your family loads tall stemware or oddly shaped bowls regularly. The number of spray arms does not affect noise — only the motor and pump efficiency do.
Drying System: Condensation vs. Fan-Assisted
Condensation drying relies on a hot rinse that forces moisture to bead on cool stainless steel walls and drain away — it is silent but can leave plastic items wet. Fan-assisted drying, often branded as TurboDry or Heat Dry with Fan, introduces a low hum during the drying phase. If absolute silence is your priority, condensation-only systems are quieter, but you will need to towel-dry some loads. Many premium models now offer fan drying with noise-dampened motors that stay nearly inaudible.

In‑Depth Reviews
1. Kenmore 22-14699 Elite 24″ Built-In Dishwasher
At 42 dBA, the Kenmore Elite is the quietest unit in this lineup — a full 3 dBA lower than the next-quietest competitors. The Whisper-Quiet wash is achieved through a combination of a variable-speed motor, dense sound insulation, and the QuietWash option that further reduces motor aggressiveness during the main wash phase. In real-world terms, this machine is barely audible from three feet away, making it the top choice for open-plan kitchens where the dishwasher sits near the dining table.
The UltraWash Plus system employs three pressurized spray arms that deliver fresh, filtered water from every angle. The Accela Wash cycle tackles heavy soil in under an hour, while the Sani Rinse raises water temperature to 155°F for NSF-certified sanitization. The TurboDry fan pulls moisture out of the tub — it adds a faint air-moving sound during the drying phase, but the overall noise profile remains far below what typical 50-dBA machines produce.
The adjustable TurboFlex third rack adds 35% more loading space for utensils, and the MoreSpace Plus upper rack adjusts to three heights to accommodate tall serving bowls or stemware. The hidden touch controls and LED floor light provide a clean front panel without protruding buttons. Only two downsides emerge: the machine requires a power cord (not included), and a small number of owner reports mention unresponsive customer support when warranty issues arise.
What works
- 42 dBA rating is genuinely whisper-quiet in real use.
- TurboDry leaves plastics dry, eliminating post-cycle towel drying.
- Third rack and adjustable upper rack increase loading flexibility.
What doesn’t
- Power cord is not included and must be purchased separately.
- Warranty support is reportedly inconsistent.
2. Sharp SDW6767HS Smart Dishwasher
The Sharp SDW6767HS earns its place on this quiet-list with a library-quiet 45 dBA rating, which means you can run it during a phone call without needing to raise your voice. The real differentiator here is the smart-home integration: the dishwasher pairs with Amazon Alexa for voice control over cycles, modes, Wash Zone selection, and even the child lock. No other dishwasher at this decibel level offers such complete voice automation.
Beyond the smart features, the interior LED lighting provides a clear view of the stainless steel tub during loading and unloading — a convenience that is surprisingly rare at this price tier. The stainless steel interior resists odors and staining, and the heated dry with fan assist ensures dishes emerge dry without lingering moisture spots. The third rack is adjustable and removable, letting you reconfigure the interior for large pots or delicate stemware.
On the downside, a power cord is not included, and the installation process requires accessing the water and power connections at the front left and right sides. Some owners have reported control board failures within the first few months, and Sharp’s technical support documentation has been called confusing. For tech-savvy buyers who prioritize voice control and quiet operation, this Sharp model offers features that few competitors match at a similar dBA rating.
What works
- Full Alexa voice control for hands-free operation.
- Interior LED lights make loading and unloading easier.
- 45 dBA rated noise — genuinely quiet in practice.
What doesn’t
- Power cord not included; no wiring guide in the box.
- Reliability is inconsistent — some units fail within months.
3. Kenmore 22-14632 24″ Built-In Dishwasher
The Kenmore 22-14632 hits the sweet spot between quiet operation and productive drying at 49 dBA. While it is not the absolute quietest model on this list, the inclusion of TurboDry — a fan-assisted system that pulls warm, moist air out of the tub — makes it the best choice for households that run mixed loads of glass, ceramic, and plastic. Plastics come out fully dry, eliminating the need for post-cycle towel drying that condensation-only machines demand.
The UltraWash Plus system uses three pressurized spray arms that channel fresh filtered water from every direction, eliminating the need to rinse dishes before loading. Owner reports confirm that even burnt-on food from baking sheets comes clean on the Accela Wash cycle, which finishes in about 50 minutes. The 15-place-setting capacity is among the largest in this segment, and the removable third rack adds a dedicated space for utensils and lids without crowding the lower basket.
The 49 dBA noise level is low enough to allow conversation in the adjacent room, though the TurboDry fan introduces a soft hum during the drying phase that some sensitive listeners notice. The touch controls are flush with the door, and the flush-mount handle gives a clean professional look. A minority of owners reported that the machine arrived with cosmetic damage or that the electronics failed within a year, so careful handling during delivery and installation is advised.
What works
- TurboDry fan dries plastics without wet spots.
- 15 place settings is one of the largest capacities available.
- Accela Wash cleans heavily soiled dishes in under an hour.
What doesn’t
- TurboDry fan is audible — it is not silent.
- Some units arrive with cosmetic damage or door misalignment.
4. KoolMore 24″ Panel Ready Dishwasher KM-DW2445-PR
The KoolMore KM-DW2445-PR is the only panel-ready dishwasher in this lineup, meaning you can attach a custom cabinet front to make the appliance disappear into your kitchen joinery. The 45 dBA noise rating puts it among the quietest models here, yet the design focus is on seamless integration rather than raw decibel numbers. The stainless steel interior resists corrosion and thermal shock, and the two ergonomic racks feature pop-up tines for custom load configurations.
The top pull-out utensil rack is ideal for long spatulas, spoons, and turners that would crowd the lower baskets. The push-button controls are recessed on the top edge of the door, keeping the front panel completely clean. The machine holds up to 14 place settings, matching the capacity of many standard built-ins, and the energy-saving cycle uses less water and power than the heavy-duty program.
Installation requires some woodworking skill because the cabinet door panel must be notched and attached — the included instructions are notably poor according to several owner reports. The wheel alignment on the lower rack can also be finicky, occasionally requiring a manual lift to slide in smoothly. For buyers who prioritize a hidden look and above-average quietness, this KoolMore model delivers, but only if you are comfortable with DIY cabinet work.
What works
- Panel-ready design allows full custom cabinet integration.
- 45 dBA noise level is genuinely quiet during operation.
- Stainless steel interior ensures durability and easy cleaning.
What doesn’t
- Door panel and hardware must be sourced and fitted by the buyer.
- Lower rack wheels may require alignment out of the box.
5. Fisher Paykel DD24SAX9 24″ Drawer Dishwasher
The Fisher Paykel DD24SAX9 is a single-drawer dishwasher that operates at 45 dBA, making it one of the quietest drawer-style machines available. The drawer design eliminates the need to bend down for loading and unloading — a genuine ergonomic advantage for users with back issues or mobility limitations. With a capacity of 7 place settings, it is best suited for households of one to two people or as a secondary unit in a wet bar or island.
Six wash cycles including a Rapid Wash option let you handle quick clean-ups or full loads. The SmartDrive motor uses a direct-drive system with fewer moving parts, contributing to both quiet operation and long-term reliability. ENERGY STAR certification means it uses less water and electricity than many full-size built-ins, and the stainless steel interior resists rust and staining.
The main drawback is the limited capacity: at 7 place settings, you cannot fit large pots or sheet pans, and larger households will find themselves running multiple loads per day. A significant number of units also arrive with cosmetic damage due to poor packaging, so inspect the box carefully upon delivery. For tight kitchens, RVs, or bar areas where noise matters more than raw capacity, this Fisher Paykel drawer is a superb quiet choice.
What works
- Drawer design is ergonomic — no bending required to load.
- 45 dBA noise rating is genuinely quiet in real use.
- SmartDrive motor is reliable and energy efficient.
What doesn’t
- 7 place settings is too small for families larger than two.
- Frequent reports of units arriving damaged in transit.
6. COSMO COS-DIS6502 24″ Dishwasher
The COSMO COS-DIS6502 is a budget-minded built-in that achieves noise levels as low as 45 dBA, thanks to pre-installed exterior sound-insulating pads. At this price tier, finding a machine that hits the same low-dBA territory as units costing 50% more is uncommon. The 12-place-setting capacity is slightly below the 14–15-setting standard, but it is sufficient for most households.
The four wash cycles — Pots & Pans, Normal Wash, China Crystal, and Quick Wash — cover the essential use cases without overcomplicating the interface. The touch-enabled control panel is mounted on top of the door, keeping the front face clean and preventing accidental presses while loading. The multiple filter system separates soiled and clean water, reducing water consumption without sacrificing cleaning power.
Where the COSMO falls short is the bottom rack wheel design — several owners report that the wheels do not roll smoothly on the track, requiring a manual lift to seat the rack properly. The Heated Dry function also struggles with plastic items, leaving them wet unless you use the Extra Dry option. For buyers who need quiet operation on a budget and are willing to tolerate minor rack and drying quirks, the COSMO delivers tremendous decibel value.
What works
- 45–51 dBA noise level at a significantly lower price point.
- Sound-insulating pads reduce vibration and mechanical noise.
- Touch control panel is easy to clean and unobtrusive.
What doesn’t
- Bottom rack wheels often do not roll smoothly.
- Plastic items may remain wet after the Heated Dry cycle.
7. Kenmore 22-14599 24″ Built-In Dishwasher
At 51 dBA, the Kenmore 22-14599 sits right at the boundary where most people would consider a dishwasher quiet — it is audible if you stand in the same room, but it will not disrupt conversation in an open kitchen. What sets this model apart is the 50-minute Express Cycle, which cleans a full load faster than any other machine in this lineup. For busy households that need clean dishes on a tight schedule, this speed advantage is significant.
The three-stage UltraWash Filter captures particles as fine as a grain of sand and drains them away, preventing redeposit onto dishes. The SmartWash sensor detects soil levels and automatically adjusts water temperature, pressure, and cycle time — a hands-off approach that consistently delivers clean results without the user needing to guess which cycle to select. The SmartDry Plus system uses condensation only, keeping the drying phase completely silent.
The main compromise with the 51 dBA rating is that it is not as quiet as the sub-45 dBA models, and owners in smaller homes report hearing the water fill and spray arm rotation clearly. Some units also arrive with visible damage to the black finish, and the drying performance on plastic items is only average due to the condensation-only system. For speed-focused buyers who can accept moderate noise, this Kenmore offers excellent value.
What works
- Express Cycle finishes a full load in only 50 minutes.
- SmartWash adjusts water temp and pressure automatically.
- Condensation drying is completely silent during the dry phase.
What doesn’t
- 51 dBA is audible — not truly whisper-quiet.
- Plastic items may remain wet after the cycle ends.
8. Kenmore 22-14585 24″ Built-In Dishwasher
The Kenmore 22-14585 is the entry-level quiet option in this guide, operating at 57 dBA — noticeably louder than the premium models above it, but still quieter than older-generation dishwashers that frequently hit 60+ dBA. The key strength here is value: you get the same UltraWash 3-stage filter and SmartWash sensor technology found in Kenmore’s higher-tier models, but at a substantially lower cost.
The 57 dBA noise level means you will hear the machine running, especially during the water fill and drain phases. However, the three-stage filter prevents food particles from redepositing, so dishes come out clean even without pre-rinsing. The SmartDry system uses condensation drying, which is silent, and the Half Load option lets you run smaller loads when the upper rack is only partially full. The stainless steel tub and adjustable upper rack add flexibility for loading tall items.
The main drawbacks are the higher noise floor — at 57 dBA, this machine is not suitable for open-plan kitchens or late-night runs near sleeping areas. The touch controls are sensitive, occasionally registering accidental presses, and the drying performance on plastic items is mediocre. For buyers on a strict budget who still want a stainless steel tub and smart wash features, this Kenmore is a solid entry point, but it is not the quietest option.
What works
- 3-stage UltraWash Filter prevents food redeposit effectively.
- SmartWash adjusts temperatures and pressure automatically.
- Stainless steel tub provides durability and condensation drying.
What doesn’t
- 57 dBA noise level is the loudest in this guide.
- Touch controls can register accidental presses.
9. Frigidaire 18″ ADA Compact Dishwasher
At 52 dBA, the Frigidaire 18-inch compact dishwasher is among the quietest smaller built-ins available. The dual spray arm system — one on the top rack and one on the bottom — ensures thorough coverage in a smaller tub, and the NSF-certified Sanitize Cycle raises water temperature high enough to kill bacteria. With 8 place settings, it is suitable for small households, apartments, or as a secondary dishwasher in an island or bar area.
The Heating Drying system uses a traditional heating element to dry dishes, which is silent during the drying phase, unlike fan-assisted systems. The six cleaning cycle options include Energy Saver, Heavy Wash, and Rinse, giving you flexibility based on load soil level. The ADA-compliant height makes it accessible for wheelchair users, and the front control panel is easy to reach and read.
The compact size means you cannot fit large baking sheets or tall pots, and the heating element is physically smaller than full-size models, resulting in less effective drying, especially for items on the lower rack. Some owners report that the drying performance has declined compared to older Frigidaire models, with plastic items often emerging wet. For small kitchens where noise is a concern, this compact machine offers reasonable quietness, but the drying trade-off is real.
What works
- 52 dBA noise is quiet for a compact built-in.
- ADA-compliant height improves accessibility.
- Dual spray arms provide effective coverage in a small tub.
What doesn’t
- 8 place settings fit only small loads — no large pots.
- Heating element is small, reducing drying effectiveness.
10. BLACK+DECKER 18-Inch Portable Dishwasher BPD8B
The BLACK+DECKER BPD8B is a portable dishwasher on wheels, designed for apartments and rentals where permanent installation is not possible. It does not carry a formal dBA rating, but owner reports describe it as moderately quiet — comparable to a 55 dBA built-in during the wash cycle. The Quick Connect assembly hooks directly to a standard faucet, eliminating the need for direct plumbing or permanent installation.
With 8 place settings, it fits an average daily load for a one- or two-person household. The six wash programs — Normal, Heavy, Rapid, Glass, Eco, and 90-min — cover most use cases, and the stainless steel tub provides durability and helps with condensation drying. The adjustable upper rack lets you fit taller items on the lower level, and the LED display keeps cycle information visible at a glance.
The biggest issue is the faucet adapter — a significant number of owners report that the included adapter does not fit standard kitchen faucets, requiring a trip to the hardware store for the correct fitting. The hose also leaks slightly at the connection point for some users, and the cord and hose management is awkward, leaving loose loops behind the unit. For renters who need portable quietness, this BLACK+DECKER works, but expect a minor hardware hassle during setup.
What works
- Portable on wheels — no permanent installation needed.
- Six wash programs cover diverse soil levels.
- Stainless steel tub adds durability and drying performance.
What doesn’t
- Faucet adapter often does not fit standard kitchen faucets.
- Hose and cord management is messy and poorly designed.
11. Fisher and Paykel Double DishDrawer DD24SAX9
The Fisher and Paykel Double DishDrawer is the most expensive and most unusual dishwasher in this lineup, with two independent drawers that can run simultaneously or separately. Each drawer holds 7 place settings, giving a combined capacity of 14. The separate drawers let you wash delicate glassware in one drawer while running a heavy-duty cycle in the other — a flexibility no single-tub dishwasher can provide. The noise level is comparable to the 45 dBA single-drawer model, making it one of the quietest full-capacity options available.
The six wash cycles include a Rapid Wash for quick turnaround, and the SmartDrive motor reduces vibration and mechanical noise significantly. The drawer design eliminates the need to bend — each drawer pulls out at waist height, reducing back strain during loading. The ENERGY STAR certification means even running both drawers uses less water than a standard 14-place-setting built-in on a full cycle.
The main limitation is cost — this is the premium option by a wide margin. The drawers cannot accommodate 12-inch dinner plates; only 10-inch plates fit, which may be a deal-breaker for households with large dinnerware. A disappointing number of units also arrive with cosmetic damage due to poor packaging, and replacement parts can be difficult to source. For households that prioritize noise reduction, flexible zoning, and ergonomic loading above all else, the Double DishDrawer is unmatched, but it demands a serious financial commitment.
What works
- Two independent drawers allow separate cycles simultaneously.
- Drawers load at waist height — no bending required.
- Quiet operation at approximately 45 dBA per drawer.
What doesn’t
- Very expensive compared to single-tub alternatives.
- 10-inch plate limit — cannot fit standard 12-inch dinner plates.
Hardware & Specs Guide
Noise Rating (dBA) and What It Means
The decibel scale is logarithmic: a 3 dBA reduction halves the sound energy output of the machine. At 42 dBA, the Kenmore Elite is inaudible from 3 feet away; at 52 dBA, the Frigidaire compact is clearly audible but not disruptive. For open-concept kitchens, target 45 dBA or lower. For enclosed kitchen spaces, 49–52 dBA is acceptable. Models without a formal dBA rating, like the BLACK+DECKER portable, typically operate in the 55–60 dBA range and should be avoided for quiet-sensitive spaces.
Spray Arm Configurations
Two-arm systems (bottom and top) are standard on compact and budget models. Three-arm systems add a dedicated arm for the third rack or upper basket, providing direct water pressure to utensils and stemware. The Kenmore Elite and 22-14632 both use three arms. Fisher Paykel drawer designs use a single spray arm per drawer, but the smaller tub volume makes coverage less critical — the arm reaches all surfaces effectively in a 7-place-setting space.
Drying Technology: Condensation vs. Fan-Assisted
Condensation drying uses a final hot rinse that forces water vapor to bead on stainless steel walls and drain away — it is silent, but plastic items often remain wet. Fan-assisted systems (TurboDry, Heat Dry with Fan) use a small blower to pull moisture out of the tub — they add a faint air-moving sound but dry plastics completely. In quiet-focused rankings, condensation-drying machines have an edge in noise floor, but the end-user trade-off is that you may need to hand-dry some loads.
Third Rack and Capacity
A third rack — typically located at the very top or as a removable tray — adds 30–35% more utensil loading space without reducing lower-rack capacity. Models with a fixed third rack (Kenmore 22-14632, Sharp SDW6767HS) are best for households that use many utensils or small lids. Models without a third rack (COSMO, Kenmore 22-14585) rely on a cutlery basket in the lower rack, which reduces space for large pots. For quiet-focused households that run frequent loads, the third rack improves efficiency by reducing the number of cycles needed per day.
FAQ
Does a lower dBA rating always mean a quieter real-world experience?
What should I expect from a 42 dBA dishwasher that I cannot get from a 51 dBA model?
Is fan-assisted drying always louder than condensation drying?
Can I make a 57 dBA dishwasher quieter after installation?
Final Thoughts: The Verdict
For most households seeking the quietest possible clean, the and quietest dishwasher winner is the Kenmore 22-14699 Elite because its 42 dBA rating, TurboDry fan drying, and three-spray-arm UltraWash system deliver silent, spotless results without the capacity compromises of drawer-style alternatives. If you value voice control and interior LED lighting for easier loading, grab the Sharp SDW6767HS. And for ergonomic loading in small kitchens or bar areas, nothing beats the Fisher Paykel DD24SAX9 single drawer — it is quiet, easy to access, and energy efficient.
