Check Price on Amazon

The Kenmore 22-14599 brings a full 24-inch footprint with 14 place settings and a three-stage UltraWash filter that captures particles as small as fine sand and flushes them away—no manual pre-rinsing required. Its SmartWash sensor adjusts water temperature, pressure, and cycle time based on soil level, while the SmartDry Plus system uses hot water to force condensation down the drain for optimized drying without a heating element constantly running.

The MoreSpace adjustable upper rack raises, lowers, or removes entirely to fit pots, tall stemware, or baking sheets, and the half-load option handles smaller daily loads efficiently. A UL-certified Sani Rinse option holds the interior at sanitizing temperature, and the Express Cycle finishes a full load in 50 minutes—useful for quick turnarounds between meals. At 51 dBA, it is noticeable in an open kitchen but not disruptive.

Owners report reliable cleaning even without pre-scrubbing, though some units have arrived with cosmetic damage and a small number of users experienced random mid-cycle shutoffs that warranty service could not resolve. The leak detection system adds peace of mind against water damage in a built-in installation.

The Fisher Paykel DD24SAX9 is a single-drawer dishwasher that slides out like a cabinet drawer, eliminating the bending required with drop-door models. It holds 7 place settings, making it ideal for couples or small households, and its 45 dBA operation is quieter than a typical conversation—you can run it during a dinner party without raising voices. The built-in, drawer-style design also allows partial opening mid-cycle to add a forgotten dish without flooding the floor.

Six wash cycles include a Rapid Wash for quick turnarounds, and the ENERGY STAR rating confirms reduced water and energy consumption compared to traditional full-size units. The unit measures 23.57 inches wide by 16.13 inches tall, so it fits into a standard 24-inch cabinet space but requires significantly less vertical clearance. At 60 pounds, installation is manageable but requires a dedicated electrical circuit and standard 3/8-inch water line.

Reviews highlight the quiet cleaning performance and low utility impact, though the 7-place-setting capacity means larger pots and baking sheets may need hand washing. Some buyers received units with dented stainless panels due to poor packaging, but Fisher & Paykel’s customer service has been responsive with replacement panels. The single-drawer format is best suited as a secondary dishwasher in a bar area or for an aging user who wants to avoid stooping.

The Fisher Paykel Double DishDrawer stacks two independent drawers to provide 14 place settings of total capacity—the same as a standard 24-inch dishwasher but with the flexibility of running each drawer separately. You can wash a full load of dinner plates in the top drawer while running a light rinse cycle for glasses in the bottom drawer, or use one drawer for soiled dishes while the other holds clean items. The SmartDrive system uses few moving parts for reliable long-term operation.

Each drawer operates at 45 dBA, making the entire unit virtually silent. The touch controls are intuitive, and the drawers slide out smoothly for easy loading without bending. The unit is ENERGY STAR certified, and the DishDrawer technology allows simultaneous or independent cycles—a feature that couples or empty-nesters appreciate for matching load size to real-time need. The top drawer accommodates 10-inch plates as the maximum diameter.

Buyers consistently praise the quiet performance and the ability to handle separate loads, but the premium price sits well above the mid-range category. Some units arrived damaged due to inadequate packaging, though Fisher & Paykel’s customer service has been responsive in those cases. Professional installation took 6 hours for one reviewer due to complex plumbing requirements, so factor in installation costs.

The COSMO COS-DIS6502 is a 24-inch built-in dishwasher with a 45 dBA noise rating—quiet enough to run during a movie with the door open. It holds 12 place settings and features a fingerprint-resistant stainless steel finish paired with a stainless steel tub for heat retention during drying cycles. The touch-enabled control panel sits at the top of the door, keeping it hidden when closed, and the surface wipes clean easily.

Four wash cycles with two options (including Heated Dry) cover normal, heavy, rapid, and sensor wash modes. The multiple filter system separates soiled and clean water to improve efficiency, and the unit is UL listed and ENERGY STAR certified. The upper rack accommodates large or irregular dishes, and the lower rack has capacity for plates, bowls, and cookware. Exterior sound-insulating pads are pre-installed to reduce mechanical noise further.

Owners report that the unit cleans well only if dishes are pre-rinsed—stubborn dried-on food may require another cycle. Some users experienced a control panel that enters a blinking mode, requiring a power cycle to reset. The bottom rack wheels do not roll smoothly for all users, occasionally needing a lift to align properly. At this noise level, the mechanical wash sound is barely audible, but the overall reliability track record is mixed.

The KoolMore KM-DW1852-PR is an 18-inch undercounter dishwasher with a panel-ready front that accepts a custom cabinet panel for a seamless, hidden finish. It holds 8 place settings in two ergonomic racks with pop-up tine holders that allow flexible loading. The stainless steel inner tub provides heat retention for drying, and the 52 dBA noise rating is moderate—noticeable but not intrusive in a closed kitchen.

Five wash cycles (Auto, Normal, Heavy, Delicate, Rinse) and an LED display give clear status feedback. The unit operates at 4.3 cubic feet of capacity, and the removable utensil basket adds convenience for busy households. The low-profile touch controls keep the front clean, and the unit can be installed as freestanding or built-in. At 17.6 inches wide, it slides into a standard 18-inch cabinet bay.

Users report that the dishwasher works well with soft water and organic detergent, though some find the buttons unclear without labeling. The panel-ready design requires woodworking skills to attach a cabinet door—no template or detailed instructions are included. A small number of owners reported the door latch failing or the upper spray assembly falling apart after a few months. For those who can handle the custom door installation, the KoolMore offers a clean integrated look at a competitive price.

The SPT SD-9263W is a freestanding portable dishwasher that rolls on casters and connects to the kitchen faucet, making it suitable for apartments and rentals where built-in installation is not possible. It holds 5 gallons of water per cycle and features a stainless steel inner tub. The full control panel includes an auto program, and the unit measures 18 inches wide—fitting into tight spaces between cabinetry and counters.

The included faucet adapter and drain hose allow quick hookup without permanent plumbing changes. Energy consumption is 237 kWh per year, and the unit is ENERGY STAR certified. Controls are full-panel push buttons, and the LED display remains visible only when the door is open. The top rack spray arm detaches for cleaning, and the unit rolls easily on smooth flooring.

Long-term owners report the unit still works after 6 years, though the hoses at the base tend to loosen and require weekly tightening to prevent leaks. Build quality uses thin sheet metal that feels delicate, and the cord/hose storage is poor. Dish drying is incomplete with plastic items—quality detergent helps. This portable model is best for a single person or couple who cannot install a built-in unit and does not mind the weekly hose check.

The EdgeStar BIDW1802SS is an 18-inch built-in dishwasher with a built-in leakage sensor that automatically shuts off water flow when a leak is detected—a critical safety feature for undercounter installations in homes with wood floors or finished basements. It fits 8 place settings in a stainless steel interior, with six wash cycles (Heavy, Normal, ECO, Glass, Rapid, Rinse) and three options (Sanitize, Hi Temp, Heated Dry).

The unit operates at 52 dBA, which is moderate and suitable for a closed kitchen. It measures 17.6 inches wide and fits into a standard 18-inch cutout. The stainless steel basket materials resist rust over time, and the LED display gives clear cycle feedback. The included drain hose and inlet hose support straightforward installation. Energy consumption is 234 kWh per year, matching ENERGY STAR expectations.

Owner reviews are split: many praise the value, quiet operation, and customer service, while a recurring complaint is that dishes remain dripping wet after the heated dry cycle. Some users report the LSB error code appearing on the display, requiring a power cycle to clear, and leaks at the water inlet port even with professional installation. The leakage sensor is a genuine safety advantage, but the drying performance may require leaving the door cracked overnight.

The EdgeStar BIDW1802WH is the white counterpart to the BIDW1802SS, sharing the same 18-inch footprint, 8-place-setting capacity, and leakage sensor technology. The white gloss finish appeals to kitchens with lighter cabinetry or older appliance color schemes. Six wash cycles include Heavy, Normal, ECO, Glass, Rapid, and Rinse, with Heated Dry, Hi Temp, and Sanitize options available on applicable cycles.

The stainless steel basket material resists rust, and the unit operates at 52 dBA. The leakage sensor automatically shuts off water flow, which is a standout safety feature at this price point. At 17.6 inches wide and 32.5 inches tall, it fits standard undercounter cavities. The push-button controls are straightforward, and the LED display provides cycle status. Energy use is 234 kWh per year.

Reviews mirror the stainless version: owners appreciate the cleaning performance and customer service, but the heated dry is often ineffective, leaving dishes and plastics sopping wet. The LSB error code appears on some units, and leaks at the water inlet have been reported despite professional installation. The white finish is harder to find than stainless, making this a good option for those who need a white color match and accept the drying limitation.

The SPT SD-9254SSA is an 18-inch built-in dishwasher with a stainless steel tub and a dedicated heating function during the drying cycle—a feature that separates it from budget models that rely solely on passive condensation. It holds 8 place settings and offers six wash programs plus a time delay feature (1-24 hours). The rinse aid warning indicator alerts you when to refill, and the error alarm displays fault codes for troubleshooting.

The unit is ENERGY STAR certified with an annual energy consumption of 234 kWh. The full console control panel includes automatic dispensers for detergent and rinse agent. The included top-mount brackets simplify installation, and the drain hose and inlet hose are provided. The stainless steel finish resists fingerprints reasonably well, and the interior stainless tub supports heat retention for effective drying and sanitization.

Owner reports are generally positive: the dishwasher cleans to a sparkling finish and heats water sufficiently for sanitization. However, a notable minority finds that the heated dry function does not actually dry dishes, leaving them dripping wet even when the Heated Dry and Sanitize buttons are selected. The door latch is a known weak point on older SPT models, though the current version has an enhanced latch. Installation instructions are poorly written, but the mechanical design is identical to more expensive brands.

The Midea 18-inch built-in dishwasher is a slimline model at 17.6 inches wide that accommodates 8 place settings and plates up to 11 inches tall—enough for standard dinner plates without restricting the spray arm. The digital control panel with LED display offers six programs: Heavy, Normal, ECO, Delicate, Quick, and Rinse, plus three functions (Heated Dry, Hi-Temp, and Sanitize). The Hi-Temp wash maintains water at 136°F to tackle heavy soil, making it suitable for baby bottles and children’s dinnerware.

The stainless steel tub supports heated dry performance, and the unit is ENERGY STAR certified. The adjustable legs allow height customization from 32.4 inches, and the included top-mount brackets secure the unit under the counter. The integrated handle design keeps the front clean. The unit requires standard 120V electrical connection and a 3/8-inch water supply line.

Owner satisfaction is high for size and quiet operation, but some users note that the lower rack sits too close to the top rack, causing normal plates to obstruct the spray arm. The tines angle outward, so plates can hit the tub walls. After several months, some units only run ECO and Delicate cycles unless the buttons are pressed repeatedly. Heated dry is less effective on plastics. The Midea is a strong option for a tight budget if you are willing to experiment with plate placement and loading strategy.

The Honeywell 18-inch dishwasher claims 14 place settings—an unusually high number for an 18-inch unit—backed by a stainless steel tub and six washing programs (Pots & Pans, Normal, China, Quick Wash, Rinse Only, Energy Saver). The 24-hour delay start adds scheduling flexibility, and the unit is ADA-compliant and ENERGY STAR certified. Dimensions are 22.6 inches deep by 18 inches wide by 32.4 inches tall.

Push-button controls keep the interface simple, and the included cutlery basket supports the high place-setting count. The stainless steel tub aids heat retention, and the recessed handle avoids protruding hardware in tight kitchens. The unit is designed for built-in installation and measures 22.6 inches in depth, which fits under standard counter overhangs.

Buyers praise the quiet operation and effective cleaning for an entry-level model. Some report the lower basket wheel occasionally derails on the track, and large pots and bowls require hand washing. A critical minority received units with an E4 error code on arrival, and the manufacturer’s replacement process required paid reinstallation. The Honeywell is a high-value option if you prioritize capacity over long-term reliability and can handle potential wheel alignment issues.
