An automatic dishwasher is one of the most transformative appliances in a modern kitchen, saving hours each week while delivering a cleaner, more sanitary result than hand washing. The challenge is finding a model that fits your space, handles baked-on messes, and operates quietly enough to run while you sleep.
I’m Mohammad Maruf — the founder and writer behind WellFizz. My research for this guide involved analyzing over 50 customer reports and cross-referencing technical specifications across 11 different models to identify the real-world performance differences that matter most.
Whether you need a slim 18-inch unit for a compact kitchen or a full-size machine with a third rack, this guide breaks down the best options available today. You’ll find the best automatic dishwasher by matching capacity, noise level, and cleaning power to your home’s specific needs.
How To Choose The Best Automatic Dishwasher
Selecting a dishwasher involves more than picking a brand name. You need to consider the physical dimensions of your cabinet cutout, the number of people in your household, your tolerance for noise, and the types of dishes you wash most often.
Width and Capacity
The vast majority of dishwashers are 24 inches wide, which fits standard under-counter spaces. If your kitchen lacks that room, 18-inch models are available and typically hold 8 place settings. Capacity is stated in place settings, but real-world loading varies — look for adjustable racks and foldable tines that let you fit larger pots or odd-shaped items.
Noise Level
Decibel ratings (dBA) range from roughly 44 (library-quiet) to 55 (noticeable hum). Every 3 dBA difference is a doubling of perceived sound. If you have an open floor plan or run the dishwasher at night, prioritize models rated at 47 dBA or lower.
Cleaning and Drying Performance
A stainless steel interior retains heat better than plastic, aiding the drying process. Look for models with heated dry, fan-assist drying, or condensation drying. Soil sensors automatically adjust cycle length and water temperature based on how dirty the load is, which saves energy without compromising results.
Sanitization and Certifications
NSF-certified sanitize cycles use high-temperature rinse water to kill 99.9% of bacteria, a key feature for households with young children or immunocompromised members. Energy Star certification ensures the unit meets federal efficiency standards, lowering your utility bills over time.

In‑Depth Reviews
1. Sharp SDW6767HS Smart Dishwasher
This Sharp model stands out with its 45 dBA operation — among the quietest on the market — and smart home integration that lets you start or check cycles through Alexa. The stainless steel interior and fan-assisted heated dry tackle plastic Tupperware that many dishwashers leave wet, and the interior LED lights make unloading in dim lighting much easier.
The adjustable third rack provides dedicated space for utensils and flatware, freeing up the lower racks for pots and plates. With a 14-place-setting capacity, this unit handles large family dinners without requiring pre-rinsing — soil sensors automatically adjust the cycle to match the load’s dirt level.
Buyers consistently praise the whisper-quiet performance, noting they often forget the cycle is running. The main consideration is that no power cord is included, so you’ll need to purchase one separately or hire an electrician for installation. Overall, this is the most feature-rich and quiet option in the lineup.
Why it’s great
- Ultra-quiet 45 dBA operation is nearly silent
- LED interior lighting for easy loading and unloading
- Alexa voice control adds modern convenience
Good to know
- Does not include a power cord
- Some users reported control board issues after several months
2. Sharp SDW6726MS 24-inch Dishwasher
The Sharp SDW6726MS delivers full-size performance with a 12-place-setting capacity and a 47 dBA noise level that won’t interrupt conversations or sleep. Its three-sprayer system includes a dedicated Power Wash sprayer for heavily soiled pots and pans, and the adjustable third rack adds flexibility for utensils and small bowls.
Soil sensors automatically detect the dirtiness of the load and adjust water temperature, cycle length, and pressure accordingly — this not only improves cleaning results but also reduces unnecessary water usage. The fingerprint-resistant stainless steel finish keeps the front looking clean between wipes.
Real-world owners emphasize how quiet the unit is, with many commenting they forget it’s running. A few noted the water inlet is a 3/4-inch front connection rather than a standard 3/8-inch rear, which may require an adapter hose during installation. For large households wanting a balance of noise, capacity, and price, this is a strong contender.
Why it’s great
- Very quiet 47 dBA operation suits open floor plans
- Power Wash sprayer handles baked-on food well
- Soil sensors optimize water and energy use
Good to know
- Water inlet connection is front-facing 3/4 inch
- May need a separate adapter hose for some setups
3. Kenmore 22-14595 24″ Built-In Dishwasher
Kenmore’s 22-14595 uses a 3-stage UltraWash filter that captures particles as small as fine sand and drains them away so they can’t redeposit on dishes. The SmartWash sensor technology adjusts water temperature, pressure, and cycle time based on how dirty the load is, and a leak detection system shuts off water flow if a leak is sensed.
With a 14-place-setting capacity and a MoreSpace adjustable upper rack that can be raised, lowered, or entirely removed, this machine accommodates everything from tall stockpots to delicate stemware. The SmartDry Plus system uses hot water to force condensation down the drain for improved drying of plastics and glassware.
Owner feedback highlights the sturdy stainless steel tub and easily cleaned filter as major positives. Some users note that controls can be quirky — particularly the touch panel — and that the express cycle doesn’t activate drying. Despite these minor quirks, the combination of capacity, sensor-based cleaning, and leak protection makes it a smart choice for families.
Why it’s great
- UltraWash filter prevents food from redepositing
- Leak detection adds water damage protection
- Adjustable upper rack fits oversized cookware
Good to know
- Express cycle lacks drying function
- Touch controls can be unintuitive at first
4. KoolMore 24 in. Panel Ready Dishwasher
For kitchens where a seamless look is paramount, the KoolMore KM-DW2445-PR accepts a custom cabinet panel so the dishwasher blends in with surrounding cabinetry. It operates at a whisper-quiet 45 dBA, making it one of the most discreet machines available, and its two ergonomic racks feature pop-up and pop-down tines for flexible loading.
The top utensil rack is ideal for long spatulas and cooking spoons, keeping them out of the main racks so you maximize space for plates and pots. With a 14-place-setting capacity (8 cubic feet), this unit handles moderate-to-large loads efficiently, and the low-profile touch controls maintain a clean front appearance.
Buyers appreciate the smooth tensioned door and effective heating element. However, the unit does not ship with a cabinet panel — you must supply your own — and KoolMore does not sell them directly. The instruction manual for attaching the panel is minimal, requiring some DIY woodworking skill. It’s an excellent choice for design-conscious homeowners who don’t mind a little extra setup work.
Why it’s great
- Panel-ready for a fully integrated kitchen look
- Very quiet 45 dBA operation
- Top utensil rack frees up lower space
Good to know
- Cabinet panel must be purchased separately
- Panel attachment instructions are sparse
5. Fisher & Paykel DD24SAX9 Drawer Dishwasher
The drawer-style design of the Fisher & Paykel DD24SAX9 is a unique approach to dishwashing — instead of pulling down a door, the drawer slides out like a cabinet drawer, making loading and unloading much easier on the back. It holds 7 place settings, making it best suited for small households, RVs, or boats where space is tight.
Six wash cycles include a Rapid Wash for quick clean-ups, and the ENERGY STAR rating means it uses less water and electricity than older models. At just 45 dBA, it runs quieter than a typical conversation, so it won’t disturb a nearby living area.
Owner experiences are positive regarding its quietness and cleaning ability, but the price point is notably higher than traditional under-counter models with similar capacity. Additionally, some buyers received units with shipping damage, so purchasing from a reputable seller with a good return policy is recommended. If you prioritize ergonomics and a compact footprint over raw capacity, this drawer unit is a thoughtful choice.
Why it’s great
- Drawer design reduces bending during loading
- Very quiet 45 dBA operation
- ENERGY STAR certified for efficiency
Good to know
- Holds only 7 place settings — not for large families
- Premium price for the compact drawer form factor
6. Frigidaire 18 in. ADA Compact Dishwasher
Frigidaire’s 18-inch compact dishwasher fits into cabinets that are too narrow for full-size models while still offering a full-size cleaning experience. The dual spray arm system ensures water reaches both racks, and the NSF-certified sanitize cycle uses high-temperature water to kill bacteria — a valuable feature for households with infants or elderly members.
The heated drying system uses a bottom element to dry dishes effectively, though some newer versions have a slightly smaller coil than previous generations. The unit is ADA compliant, meaning controls are positioned at an accessible height, important for wheelchair users or those with limited reach.
Owners consistently praise the quiet 52 dBA operation and the compact size that fits where a 24-inch model cannot. The primary downside reported is that the heated dry element is less powerful than older models, sometimes leaving plastics damp. For small kitchens or secondary suites (apartments, in-law units), this is a reliable workhorse.
Why it’s great
- Fits a narrow 18-inch cabinet opening
- NSF-certified sanitize cycle for high hygiene
- ADA compliant controls
Good to know
- Heated drying element is smaller than older models
- Plastics may remain damp after the cycle
7. EdgeStar BIDW1802BL 18-inch Dishwasher
EdgeStar’s BIDW1802BL is designed for small kitchens where a leak could be catastrophic. Its integrated leakage sensor automatically shuts off the water supply when a leak is detected, protecting your floors and cabinets. With a 17.75-inch width and 8-place-setting capacity, it can replace an old trash compactor or fit into a narrow cabinet space.
Six wash cycles — Heavy, Normal, ECO, Glass, Rapid, and Rinse — plus three options (Sanitize, Hi Temp, Heated Dry) give you flexibility from delicate stemware to crusty casserole dishes. At 52 dBA, it operates with a moderate hum that won’t drown out conversation.
Long-term owners report reliable performance over several years, though some note that error codes occasionally appear and require unplugging the unit to clear them. The drying performance is adequate if you leave dishes overnight, but immediate results on plastics are mediocre. If peace of mind against water damage is a priority, the leak sensor alone makes this unit worth considering.
Why it’s great
- Automatic leak detection prevents water damage
- Six wash cycles plus sanitize option
- Compact 18-inch width fits tight spaces
Good to know
- Drying performance is average on plastics
- Error codes may require unplugging to reset
8. Honeywell 18-Inch Dishwasher
Honeywell’s 18-inch dishwasher brings a solid set of features to a compact frame. Six wash programs include heavy, normal, eco, glass, rapid, and rinse, giving you options for every type of load. The stainless steel tub helps retain heat for better drying, and the 24-hour delay start lets you run the dishwasher during off-peak hours.
The bar handle design gives it a slightly more modern look than the recessed handles on some competitors, and the Energy Star certification keeps electricity use low. With 8 place settings, it handles daily dishes for a small family or couple without issue.
Owners report good cleaning performance for the price, with several noting it fits neatly into a small kitchen. A few buyers experienced touch button failures after a couple of months, which is a risk at this price tier. The installation process can be tricky due to depth alignment with cabinet toe kicks — measure carefully before buying. Overall, it’s a decent entry-level option for those on a tight budget.
Why it’s great
- Stainless steel tub improves drying efficiency
- 24-hour delay start for off-peak operation
- Energy Star certified for low power use
Good to know
- Touch buttons can fail after several months
- Depth alignment with cabinets may require adjustment
9. SPT SD-9254SSA 18-inch Dishwasher
The SPT SD-9254SSA is the stainless steel version of the popular SD-9254 series, offering the same reliable internals with a more modern exterior. The stainless steel tub is a key upgrade over cheaper budget models, as it retains heat better than plastic and resists odors. With 8 place settings and 6 wash programs, it suits couples and small families.
The 1-to-24-hour time delay gives you flexibility to run the dishwasher overnight when energy rates are lower, and the rinse aid warning indicator reminds you when the fluid is low so you don’t get spotting on glassware. The heating function during drying cycles improves results compared to models that rely solely on condensation.
Owners highlight the sparkling clean results and easy installation, with several noting the unit shares internals with more expensive brands. The door latch has been a weak point on previous models, though the newer version seems to have addressed this. Some users report that heated dry isn’t strong enough for full drying on plastics. For the price, it’s a solid, no-frills performer.
Why it’s great
- Stainless steel tub retains heat well
- Time delay and rinse aid indicator included
- Reliable cleaning with good value
Good to know
- Heated dry may not fully dry plastic items
- Door latch could be more robust
10. Midea 18 Inch Built-In Dishwasher
Midea’s slim 18-inch dishwasher packs 6 washing programs and 3 functions — including a HI-TEMP wash that maintains water at 136°F for tackling heavy soils and sanitizing baby bottles. The digital control panel with LED display makes cycle selection straightforward, and the stainless steel tub provides durable, heat-retaining construction.
The interior is designed to accommodate plates up to 11 inches tall, and the 8-place-setting capacity handles a day’s worth of dishes for a couple or small family. The heated dry function is effective on most loads except rapid and self-clean cycles, where it is intentionally disabled.
User feedback is generally positive, noting quiet operation and spacious interior for its size. A few owners found that the lower rack sits too close to the top rack, causing some plates to block the spray arm. Heated dry performance can be inconsistent, particularly on plastic items. At this price, it’s a competitive slimline option with useful sanitization capabilities.
Why it’s great
- HI-TEMP wash reaches 136°F for heavy cleaning
- Digital LED display with clear controls
- Stainless steel tub for durability
Good to know
- Lower rack clearance can be tight for larger plates
- Heated dry not available on rapid and self-clean cycles
11. SPT SD-9254W Energy Star 18″ Dishwasher
The SPT SD-9254W is the white entry-level sibling in the SPT 18-inch lineup, ideal for budget-conscious buyers or those with an all-white kitchen aesthetic. Like its stainless counterpart, it features a stainless steel tub and heated drying, but comes at a lower tier that often appeals to renters or first-time homeowners.
With a 4.9-gallon capacity and Energy Star certification, it keeps both water and electricity bills low. The top-mount design simplifies installation in tight spaces, and the included top-mounting brackets make it easy to secure under a counter. The recessed handle keeps the front profile clean.
Customer reviews are mixed — many report excellent performance for the price, especially for small kitchens where hand washing was the only alternative. However, several buyers note that the heated dry is not as effective as premium models, and some experienced soap residue on dishes. The filter requires regular cleaning to maintain performance. For the absolute lowest cost of entry into automatic dishwashing, this unit gets the job done.
Why it’s great
- Lowest price point for an automatic dishwasher
- Energy Star certified to minimize utility costs
- Top-mount design for simple installation
Good to know
- Heated dry is less effective than premium models
- Soap residue reported by some users
