For dishwashers under $500, my best overall pick is the Honeywell 18-Inch Built-In Dishwasher, which pairs a space-saving width with a stainless steel tub. The Cosmo COS-DIS6502 is a standout for shoppers who want a full-width built-in design, while the COMFEE’ countertop models suit renters who need a portable setup. The main tradeoffs are capacity, installation requirements, and whether a compact appliance can keep up with your household’s dish load. I compare built-in, slimline, and countertop options so you can match the format to your kitchen and routine. Read on for the full breakdown and a buying guide to help narrow your choice.
Complete the kit
Key Takeaways
- Format matters more than a long feature list: the lineup spans 24-inch built-ins, narrower 18-inch models, and countertop units, each suited to a different kitchen and installation situation.
- The Honeywell 18-inch built-in stands out for space-conscious permanent installs because it combines a slim format with a stainless steel tub; buyers still need to confirm cabinet and plumbing fit.
- The Cosmo and Sharp represent different full-width priorities: Cosmo offers a tall-tub, top-control design, while Sharp lists heated dry and 12 place settings alongside a hybrid tub.
- Countertop machines trade capacity for flexibility: several COMFEE’ options and the BLACK+DECKER and SPT units can suit smaller homes, but their place settings and hookup or tank needs should match daily use.
- Similar brand names do not mean identical fit: COMFEE’ appears across built-in and portable formats, so choosing by model configuration, water connection, and drying features matters more than choosing by brand alone.

More Details on Our Top Picks
Seasons 24 in. Front Control Dishwasher in Black
The Seasons makes the most sense for buyers who want a standard-width freestanding dishwasher and prefer a black exterior. Its 52 dB rating and five cycles, including Quiet and Intensive, cover everyday loads as well as dirtier cookware. Compared with the Cosmo COS-DIS6502, it gives up the third rack, larger stated capacity, and quieter 45 dB operation, so it is a simpler choice for households that do not need those extras. The stainless steel interior is a useful durability feature, though the supplied details do not specify capacity or dimensions beyond the 24-inch width. Brand information is also inconsistent: the listing names Seasons while item details reportedly say Generic. I would choose it for the basic format and finish, while weighing that uncertainty against better-documented alternatives.
Pros:- Standard 24-inch width suits a full-size dishwasher space
- Black exterior offers an alternative to common stainless finishes
- Stainless steel interior
- Quiet cycle and Intensive cycle cover different load needs
Cons:- Brand identity is unclear in the supplied listing details
- Capacity and full dimensions are not specified
- At 52 dB, it is louder on paper than the Cosmo COS-DIS6502
Best for: Households with a standard dishwasher opening that want a black freestanding model and straightforward cycle choices.
Not ideal for: Buyers who need confirmed capacity, a recognizable manufacturer, or the quietest operation; the listing provides limited detail and the Cosmo is rated quieter.
- Width:24 inches
- Installation:Freestanding
- Color:Black
- Interior material:Stainless steel
- Noise level:52 dB
- Cycles:Normal, Intensive, Rinse, Delicate, Quiet
- Controls:Push button
- Model:SDW2FCMB
Our verdict“Choose the Seasons if you want a black, full-width freestanding dishwasher with several basic cycles and can accept limited product and brand details.”
Honeywell 18-Inch Built-In Dishwasher with Stainless Steel Tub
The Honeywell is a practical fit when a kitchen has room for an 18-inch built-in but not a standard-width machine. Its stated 8-place-setting capacity suits smaller households, while six programs and a 24-hour delay start give it more scheduling flexibility than the Seasons 24-inch model, whose listing describes five cycles but no delay timer. Energy Star certification and ADA compliance help distinguish this option on efficiency and accessibility details. The tradeoff is capacity: families who regularly wash bulky cookware or dishes for several people may find the Cosmo COS-DIS6502’s stated 16 place settings more suitable, if their opening allows a 24-inch unit. Built-in installation can also take more planning than a freestanding model. I would shortlist the Honeywell for tight kitchens, but check the opening and installation needs first.
Pros:- 18-inch width fits narrower built-in openings
- Stainless steel tub
- Six programs include pots and pans, china, and quick wash
- Energy Star certified, ADA-compliant, and equipped with a 24-hour delay start
Cons:- Eight place settings may be limiting for families or bulky daily loads
- Built-in installation may require professional setup
- The Cosmo offers a much larger stated capacity for households with a 24-inch opening
Best for: Couples or small households with an 18-inch built-in opening who want multiple programs, delay start, and stated efficiency certification.
Not ideal for: Large households or buyers who need a high-capacity machine; its stated capacity is 8 place settings and built-in installation may require professional setup.
- Width:18 inches
- Depth:22.6 inches
- Height:32.4 inches
- Capacity:8 place settings
- Programs:6 washing programs
- Tub material:Stainless steel
- Color:White
- Certifications:Energy Star, UL, ADA-compliant
- Additional features:24-hour delay start; removable cutlery basket
Our verdict“Pick the Honeywell for a narrow built-in space and modest household loads, provided its installation requirements and 8-place-setting capacity work for you.”
Cosmo COS-DIS6502 24-inch Built-In Top Control Tall Tub Dishwasher, Stainless Steel
The Cosmo earns the broadest appeal here by combining a 16-place-setting capacity, three racks, and a listed 45 dB noise level. That makes it a stronger fit for busy households than the 8-place-setting Honeywell, while its automatic Smart Wash system can adjust to load size instead of asking you to choose every setting manually. It also lists Sanitize and Heated Dry options and carries ENERGY STAR certification. The tradeoffs are practical: at 105 pounds it is a substantial built-in unit, and the supplied information says the three-prong plug and 3/8-inch pipe fitting are sold separately. Its noise details are inconsistent, with 45 dB in the specs and 51 dB elsewhere in the product information, so I would treat the quieter figure cautiously. Check the installation kit and dimensions before choosing it.
Pros:- Stated 16-place-setting capacity and three racks support larger loads
- 45 dB listed noise level is lower than the Seasons and Honeywell figures
- Smart Wash system detects load size
- ENERGY STAR certified with Sanitize and Heated Dry options
Cons:- Three-prong plug and 3/8-inch pipe fitting are not included
- Noise rating is inconsistent in the supplied product details
- At 105 pounds, moving and installing the built-in unit may take extra effort
Best for: Families with a standard 24-inch opening who wash large loads and value multiple racks and quieter operation.
Not ideal for: Renters or buyers seeking a simple plug-and-play installation, and anyone unwilling to verify the conflicting noise information or source separate fittings.
- Model:COS-DIS6502
- Dimensions:23.75 in W x 22.25 in D x 33.75 in H
- Weight:105 lb
- Capacity:16 place settings
- Noise level:45 dB listed; another supplied detail states 51 dB
- Voltage:120 V / 60 Hz
- Material:Stainless steel
- Cycles and options:4 wash cycles with 2 options, including Sanitize and Heated Dry
- Certifications:UL Listed, ENERGY STAR
Our verdict“Choose the Cosmo for high capacity, rack flexibility, and quiet-focused features if you can confirm the noise specification and plan for the separate installation parts.”
COMFEE’ 18-Inch Built-in Dishwasher with Stainless Steel Tub
This COMFEE’ stands out among the two 18-inch COMFEE’ and Midea listings for its stated 13.78-inch maximum dish height, making it the more accommodating of those two for taller plates or cookware. Its six cycles range from Heavy to Quick, while Heated Dry and Hi-Temp sanitize add options for buyers who want drying and high-temperature cleaning functions in a narrow built-in. The 8-place-setting capacity is similar to the Honeywell and Midea, so it is aimed at compact households rather than large daily loads. Compared with the Honeywell, this model lists a digital LED panel and a higher dish clearance, while Honeywell supplies a delay-start feature and ADA compliance in its details. The detergent requirement is a real ownership constraint: using the wrong soap may cause operating issues. Check detergent guidance and installation fit before buying.
Pros:- 13.78-inch stated maximum dish height exceeds the Midea’s 11-inch limit
- Heated Dry and Hi-Temp sanitize functions
- Six cycles cover heavy, everyday, delicate, quick, and rinse loads
- Stainless steel tub in a slim 17.6-inch-wide design
Cons:- Eight place settings may not suit large households
- Specific dishwasher detergent is required to avoid operational issues
- Built-in format requires a compatible opening and installation
Best for: Small households with an 18-inch built-in opening that need extra clearance for taller dishes and want heated drying.
Not ideal for: Large families or buyers who want flexible detergent choices; capacity is limited to 8 place settings and the listing warns that specific detergent is required.
- Dimensions:22.6 in D x 17.6 in W x 32.4 in H
- Capacity:8 place settings
- Tub material:Stainless steel
- Cycles:Heavy, Normal, Eco, Delicate, Quick, Rinse
- Functions:Heated Dry, Hi-Temp, Sanitize
- Certifications:Energy Star, NSF
- Maximum dish height:13.78 inches
- Controls:Digital panel with LED display
Our verdict“Choose this COMFEE’ over the Midea when taller dish clearance matters and an 8-place-setting built-in fits your household.”
Midea 18-Inch Built-in Dishwasher with Stainless Steel Tub and 8 Place Settings
The Midea targets the same narrow built-in space and 8-place-setting household as the COMFEE’, with six programs plus Heated Dry and Hi-Temp Sanitize. Its key difference is a stated 11-inch maximum dish height, which calls for a careful check if your regular plates or cookware are tall; the COMFEE’ listing allows up to 13.78 inches. That makes the COMFEE’ the more flexible choice for taller items, while this Midea may suit kitchens where dish clearance is already known and the matching footprint matters most. The supplied details also specify a maximum water temperature of 136°F. As with the COMFEE’, capacity remains limited compared with the 16-place-setting Cosmo, and this listing warns that regular soap can cause issues, so detergent choice matters. I would measure dishes and confirm the required detergent before committing.
Pros:- Slim 17.6-inch width fits compact built-in spaces
- Six wash programs cover common load types
- Heated Dry and Hi-Temp Sanitize are included
- Stainless steel tub and stated 136°F maximum water temperature
Cons:- 11-inch maximum dish height is lower than the COMFEE’ model’s stated 13.78 inches
- Eight place settings may be insufficient for larger households
- Regular soap can cause operating issues, according to the supplied details
Best for: Couples or small households with an 18-inch opening, moderate-height dishes, and a preference for heated drying and sanitize functions.
Not ideal for: Households with tall plates, oversized cookware, or large daily loads; its dish-height limit is lower than the COMFEE’ and capacity is 8 place settings.
- Dimensions:22.6 in D x 17.6 in W x 32.4 in H
- Capacity:8 place settings
- Tub material:Stainless steel
- Programs:Heavy, Normal, ECO, Delicate, Quick, Rinse
- Functions:Heated Dry, Hi-Temp, Sanitize
- Maximum dish height:11 inches
- Maximum water temperature:136°F (58°C)
- Controls:Digital LED panel
Our verdict“Pick the Midea if its 11-inch clearance fits your dishes and you want a slim built-in with heated drying and sanitize functions.”
COMFEE’ 18-Inch Built-In Dishwasher with Stainless Steel Tub
The 18-inch built-in format gives this COMFEE’ a useful middle ground: it frees counter space like a permanent appliance while taking less room than the 24-inch models in this roundup. Its eight-place-setting capacity and adjustable upper rack help fit cookware that can be awkward in countertop machines such as the BLACK+DECKER BCD6SD. The stainless steel tub and heated dry function also suit buyers who want a more conventional built-in setup in a compact kitchen. Six wash cycles cover everyday loads, while Hi-Temp and Sanitize add options for heavier cleaning. The tradeoff is that installation requires a dedicated built-in space, and heated dry is unavailable on Rapid and Self-Clean cycles. It also calls for specific detergent, so it is less flexible than a portable countertop pick.
Pros:- Slim 17.6-inch width suits kitchens with limited cabinet space
- Eight place settings and an adjustable upper rack accommodate larger cookware
- Stainless steel tub supports durability and drying performance
- Hi-Temp and Sanitize functions add options for hygiene-focused loads
Cons:- Requires built-in installation rather than a temporary faucet connection
- Heated Dry is unavailable on Rapid and Self-Clean cycles
- Requires specific dishwasher detergent to avoid operating issues
Best for: Apartment owners with an 18-inch dishwasher opening who want a built-in appliance and room for cookware
Not ideal for: Renters or households that need a movable machine, since this model requires built-in installation
- Dimensions:22.6 × 17.6 × 32.4 inches
- Capacity:8 place settings
- Installation:Built-in
- Tub material:Stainless steel
- Wash cycles:6
- Special functions:Heated Dry, Hi-Temp, Sanitize, Delay Start, Child Lock
- Water use:4.9 gallons
- Certifications:Energy Star, NSF
Our verdict“Choose this COMFEE’ if you have an 18-inch built-in opening and want more cookware room than a countertop dishwasher offers.”
EUHOMY Portable Countertop Dishwasher with 6 Programs and 40 dB Quiet Operation
The EUHOMY is the most flexible countertop choice here: its built-in 5-liter tank lets it run without a faucet connection, while a faucet hookup is available for ongoing supply. That makes it easier to place in a rental or a kitchen where plumbing changes are off the table than the BLACK+DECKER BCD6SD, which relies on its faucet adapter. At 40 dB, it is also quieter than the listed 52 dB COMFEE’ countertop model, a practical difference in an open-plan room. Its 30-plus-item load and 10.25-inch plate limit offer useful capacity for a countertop machine. The compromises are vertical clearance above the counter and limited power against burnt-on food: scrape heavy residue first. Its extended ventilation can keep dishes fresh, but drying takes time.
Pros:- Built-in water tank allows operation without a permanent water connection
- Quiet 40 dB operation suits open kitchens and shared living spaces
- Fits more than 30 items and plates up to 10.25 inches
- Baby Care/Heavy program reaches 167°F
Cons:- Needs more than 19 inches of vertical clearance above the counter
- Heavy grease and burnt-on residue should be scraped off before loading
- Continuous faucet supply requires a separate adapter
Best for: Renters and apartment dwellers who need a quiet countertop dishwasher that can run without a faucet hookup
Not ideal for: Cooks with low cabinets or frequent burnt-on cookware, because it needs extra vertical clearance and residue must be scraped off
- Dimensions:16.85 × 16.73 × 18.03 inches
- Weight:28.6 lb
- Capacity:30+ items
- Water tank:5 liters (1.32 gallons)
- Noise level:40 dB
- Programs:6
- Maximum plate size:10.25 inches
- Drying:60-minute hot air; ventilation up to 73 hours
- Certifications:ETL, DOE
Our verdict“Pick the EUHOMY if quiet operation and a self-contained water tank matter more than fast, heavy-duty cleaning.”
BLACK+DECKER BCD6SD Countertop Dishwasher, Energy Star Certified, White
Among these countertop picks, the BLACK+DECKER BCD6SD offers the clearest capacity advantage: it holds six place settings, while the EUHOMY is described by item count and the two COMFEE’ options share the same six-setting limit. Its stainless steel interior and Quick Connect faucet adapter make it a more conventional choice for households that want a roomy countertop machine without permanent plumbing. Six cycles include Glass and Heavy, giving it a practical spread for mixed loads. The size comes with a cost in convenience: at 44.1 pounds, moving it between storage and the counter is cumbersome, and its 60 dB rating is higher than the other listed countertop units. Choose it for capacity and simple hookup, but skip it if you need a light, quiet machine or a full-size dishwasher load.
Pros:- Six-place-setting capacity is substantial for a countertop model
- Quick Connect adapter avoids permanent plumbing
- Stainless steel interior supports durability and heat retention
- Six cycles include Glass, Eco, Speed, and Heavy
Cons:- At 44.1 pounds, it is heavy to move or store
- 60 dB operation is louder than the EUHOMY and COMFEE’ countertop options
- Countertop capacity remains limited compared with built-in models
Best for: Small households that want six place settings on the counter and can leave the appliance in one spot
Not ideal for: People who need to move or store their dishwasher often, or who prioritize quiet operation
- Model:BCD6SD
- Capacity:6 place settings
- Wash cycles:6
- Installation:Countertop with Quick Connect faucet adapter
- Interior material:Stainless steel
- Dimensions:19.7 × 21.6 × 17.24 inches
- Weight:44.1 lb
- Noise level:60 dB
- Maximum plate size:10 inches
Our verdict“Choose the BCD6SD if countertop capacity and a straightforward faucet hookup matter more than low weight or quiet running.”
COMFEE’ Countertop Dishwasher, Portable Energy Star Model with 6 Place Settings and 8 Washing Programs
This COMFEE’ stands out for eight wash programs, including Baby-Care, Glass, Speed, and Mini-Party, giving small households more ways to match a cycle to the load than the six-program EUHOMY. Its six-place-setting capacity is listed as up to 70 pieces, making it suited to a couple or a small family willing to run frequent loads. At 2.77 gallons per cycle, it also offers a defined low-water-use figure, while the 154°F maximum temperature helps with greasy dishes. Faucet connection or cupboard placement gives it more installation flexibility than the BLACK+DECKER BCD6SD. However, it is still a compact appliance: plates top out at 10 inches, and the 52 dB noise level is audible in a small home. The faucet adapter may need to be sourced separately, and residual factory test water can be present at arrival.
Pros:- Eight programs cover specialized loads including Baby-Care, Glass, and Mini-Party
- Uses 2.77 gallons of water per cycle
- Six place settings can hold up to 70 pieces
- Can sit on a counter or fit into a cupboard
Cons:- Six place settings limit its usefulness for larger households
- Faucet connection may require a suitable adapter
- 52 dB operation may be noticeable in a compact living space
Best for: Couples or small families in apartments, dorms, or RVs who want multiple cycle choices and low water use
Not ideal for: Larger households or cooks who regularly wash oversized plates and heavily soiled cookware
- Dimensions:17.2 × 21.7 × 19.7 inches
- Capacity:6 place settings, up to 70 pieces
- Maximum plate diameter:10 inches
- Washing programs:8
- Water use:2.77 gallons per cycle
- Noise level:52 dB
- Maximum water temperature:154°F
- Color:Black
Our verdict“Choose this COMFEE’ if you want more cycle options than the EUHOMY and have a small household with standard-size dishes.”
COMFEE’ Portable Countertop Dishwasher, 6 Place Settings, Energy Star Certified
This COMFEE’ is the straightforward small-kitchen pick in the group: it offers six place settings, eight cycles, and a 2.77-gallon water-use figure in a countertop footprint similar to the B09ST4M8VF model. Both COMFEE’ machines list Baby-Care, Glass, and Speed options, so the choice between them is less about capacity and more about the specific cycle lineup and listed details; this version includes extra drying and high-pressure spray. Compared with the EUHOMY, it has a faucet-based setup rather than a built-in tank, and its noise level is not specified here, making quietness harder to judge. Cupboard placement adds flexibility, but the 10-inch plate limit and six-setting capacity still constrain larger households. A suitable faucet adapter may be needed, and factory testing can leave water inside on arrival.
Pros:- Eight cycles include Baby-Care and Glass programs
- Uses 2.77 gallons per cycle
- Countertop or cupboard placement accommodates small kitchens
- Extra-drying capability and high-pressure spray are included
Cons:- Six-place-setting capacity may require frequent loads for families
- Faucet connection requires a suitable adapter
- Plates are limited to 10 inches in diameter
Best for: Dorm residents, RV owners, and apartment dwellers with standard-size dishes who want multiple wash cycles in a compact footprint
Not ideal for: Households with more than a few people or cooks who use plates larger than 10 inches
- Dimensions:17.2 × 21.6 × 19.7 inches
- Capacity:6 place settings
- Water use:2.77 gallons per cycle
- Washing cycles:8
- Installation:Countertop or cupboard placement; faucet connection
- Maximum plate size:10 inches
- Certification:Energy Star
- Special cycles:Heavy, Baby-Care, Glass, Speed, Mini-party
Our verdict“Pick this COMFEE’ for a compact household dishwasher with broad cycle coverage, provided six place settings meet your needs.”
Sharp SDW6504MS 24-inch Stainless Steel Dishwasher with Pocket Handle, 52 dB, Hybrid Tub, 12 Place Settings, 5 Cycles, Heated Dry
I’d put the Sharp SDW6504MS on the list for households that want a full-width dishwasher without much cycle noise. At 52 dB, it’s quieter on paper than the Kenmore 24″ Hybrid Tub Dishwasher at 54 dBA, a useful difference for kitchens that open onto living space. Its 12-place-setting capacity, adjustable upper rack, and fold-down tines offer practical loading flexibility, while the half-load option suits smaller daily batches. Heated drying and a sanitization cycle add useful finishing options. The tradeoff is its hybrid tub: the stainless interior has a plastic floor, so buyers seeking an all-stainless tub should look elsewhere. It also holds two fewer place settings than the 14-setting Kenmore 24″ Built-In Dishwasher.
Pros:- 52 dB operating noise suits kitchens near living areas
- Adjustable upper rack and fold-down tines help fit varied dishware
- Half-load option supports smaller batches
- Sanitization cycle and heated dry provide added cycle choices
Cons:- Plastic tub floor may be less appealing to buyers seeking an all-stainless interior
- 12-place-setting capacity is below the 14-place-setting Kenmore built-in
Best for: Households with open-plan kitchens that want a quieter full-size dishwasher and flexible rack loading.
Not ideal for: Buyers who prioritize an all-stainless tub or need capacity for larger loads than 12 place settings.
- Model:SDW6504MS
- Installation:Built-in
- Width:24 inches
- Capacity:12 place settings
- Noise level:52 dB
- Cycles:5
- Tub material:Hybrid: stainless steel interior, plastic floor
- Rack adjustment:Upper rack adjusts 2 inches
Our verdict“Choose the Sharp for a quieter full-size fit and flexible loading if a hybrid tub meets your durability preferences.”
Kenmore 24″ Hybrid Tub Dishwasher – Fingerprint Resistant Stainless Steel
The Kenmore 24″ Hybrid Tub Dishwasher is aimed at buyers who want the machine to adapt its wash to the load. SmartWash sensors adjust temperature and cycle time based on soil, while pressurized UltraWash spray arms and a three-stage filter are designed to handle stuck-on food without pre-soaking. That gives it a different appeal from the Sharp SDW6504MS, whose listed strengths lean more toward quieter operation and a half-load option. The Kenmore is ENERGY STAR certified, offers a removable adjustable rack, and includes Sani Rinse and Heated Dry. At 54 dBA, it is a little louder than the Sharp, and the filter needs monthly cleaning to keep performance up. Its hybrid tub may also be a drawback for buyers set on all-stainless construction.
Pros:- SmartWash sensors adjust temperature and cycle time to soil levels
- UltraWash spray arms are designed to clean without pre-soaking
- Adjustable, removable upper rack accommodates larger items
- ENERGY STAR certification with Sani Rinse and Heated Dry options
Cons:- Filter needs monthly cleaning
- 54 dBA is louder than the Sharp SDW6504MS’s listed 52 dB
- Hybrid tub construction may not suit buyers seeking an all-stainless tub
Best for: Busy households that want soil-sensing wash adjustments and flexible space for bulky cookware.
Not ideal for: People who prefer minimal upkeep, an all-stainless tub, or the quieter operation listed for the Sharp SDW6504MS.
- Installation:Built-in
- Width:24 inches
- Capacity:12 place settings
- Noise level:54 dBA
- Tub:Hybrid
- Certification:ENERGY STAR
- Wash system:UltraWash pressurized spray arms
- Filter:Three-stage filter
Our verdict“Pick this Kenmore if sensor-guided cleaning and rack flexibility matter more to you than the Sharp’s lower listed noise level.”
SPT SD-2225DWA Energy Star Countertop Dishwasher with Delay Start & LED – White
The SPT SD-2225DWA makes sense when a standard built-in dishwasher simply will not fit. Its countertop format holds up to six place settings and accepts dishes up to 10.25 inches across, giving apartment residents a way to automate dishwashing without reserving a full cabinet-width opening. The tradeoff is capacity: it holds half the Sharp SDW6504MS’s 12 place settings, so larger households will need to run loads more often. Unlike the COMFEE’ Portable Countertop Dishwasher, the provided SPT details do not list a built-in water tank or a set of wash programs, so buyers should confirm their setup and cycle needs before choosing. Its compact height is 17.24 inches, though the 58-pound package may make placement awkward.
Pros:- Countertop format avoids taking up a built-in dishwasher bay
- Holds up to six place settings
- Fits dishware up to 10.25 inches in diameter
- ENERGY STAR certified and includes delay start and an LED display
Cons:- Six-place-setting capacity is limited beside the 12-setting Sharp SDW6504MS
- 58-pound package weight may make positioning difficult
- Provided product details do not specify wash cycles or plumbing setup
Best for: Apartment residents or office users with limited space who typically wash dishes for one or two people.
Not ideal for: Families or frequent hosts who need full-size capacity, or anyone unable to accommodate and position a 58-pound unit.
- Model:SD-2225DWA
- Type:Countertop dishwasher
- Capacity:6 place settings
- Maximum dishware diameter:10.25 inches
- Height:17.24 inches
- Certification:ENERGY STAR
- Display:LED
- Color:White
Our verdict“Choose the SPT if countertop space is available and your everyday dish loads are small.”
Kenmore 24″ Built-In Dishwasher – White
Among these built-in options, the white Kenmore stands out for 14-place-setting capacity, two more settings than the 12-setting Sharp SDW6504MS and Kenmore hybrid model. That extra room can mean fewer runs for households that build up a day’s worth of dishes. SmartWash adjusts wash temperature and time to soil levels, and SmartDry is designed to improve drying; the adjustable upper rack helps make space for taller items. A half-load option is useful when the machine is not full, and leak detection adds a practical safeguard. Compared with the countertop SPT SD-2225DWA, this is a much better match for family-sized loads, but it requires a built-in installation and a 24-inch opening. The filter also needs monthly cleaning.
Pros:- 14-place-setting capacity exceeds the other listed 24-inch models
- SmartWash adjusts cycle temperature and time to soil levels
- Adjustable, removable upper rack helps fit taller items and pots
- ENERGY STAR certification, half-load option, and leak detection
Cons:- Built-in installation may require professional setup
- Filter needs monthly cleaning
- Full-size format is unsuitable for kitchens without a 24-inch opening
Best for: Families who want full-size capacity, adjustable loading, and soil-sensing cycles in a built-in dishwasher.
Not ideal for: Renters or small-space households without a 24-inch built-in opening, and buyers who do not want regular filter maintenance.
- Installation:Built-in
- Width:24 inches
- Capacity:14 place settings
- Color:White
- Certification:ENERGY STAR
- Filter:Three-stage UltraWash filter
- Drying:SmartDry
- Other features:Leak detection, half-load option, adjustable upper rack
Our verdict“Choose this Kenmore for larger household loads if you have built-in space and can keep up with filter cleaning.”
COMFEE’ Portable Countertop Dishwasher with 5L Water Tank, 6 Programs, and Air-Dry Function
The COMFEE’ portable countertop model is the most flexible pick here for kitchens where connecting a built-in appliance is out of the question. Its 5-liter water tank allows operation without permanent plumbing, and a faucet adapter offers another setup route. Six programs include a hygiene cycle listed up to 162°F and an air-refresh mode for drying and odor removal. Its stated capacity of 30-plus items is useful for compact living, but the maximum plate size is 9.5 inches, smaller than the SPT SD-2225DWA’s 10.25-inch limit. At 62 dB, it is also the loudest option here with a listed noise level. Check the required 19.6-inch clearance above the counter before buying; the tank and compact size do not remove that fit constraint.
Pros:- Built-in 5-liter tank avoids permanent plumbing
- Faucet adapter provides an alternative water connection
- Six programs include a high-temperature hygiene cycle and air refresh

How We Picked
I organized this roundup around the decisions that shape day-to-day satisfaction: installation format, usable capacity, tub and drying details, operating features, and upkeep. Built-in models are judged on how well their width and listed configuration suit a permanent kitchen space; countertop models are judged on their smaller loads and the flexibility their portable format may offer. I also weighed practical details such as place settings, wash programs, water-tank availability, noise information when provided, and drying functions.
The order reflects how broadly useful each product appears for its intended buyer, rather than treating every dishwasher as a direct substitute. The Honeywell 18-inch built-in leads for combining a compact permanent format with a stainless steel tub. The Cosmo, COMFEE’, Midea, and other built-in models serve different installation and capacity preferences, while countertop machines rank for buyers who prioritize a smaller footprint or portability. Where the supplied product details do not specify a feature, I avoid assuming it is included.

Factors to Consider When Choosing Dishwashers Under 500
Before choosing from this list, I would start with the kitchen, household, and dish routine the machine needs to serve. A dishwasher that fits physically can still be a poor match if it requires a permanent connection you cannot provide or needs more frequent loads than your schedule allows.
Choose a Format That Fits Your Kitchen
Measure the available space, including cabinet width, door clearance, and the path from the appliance to the sink or water supply. An 18-inch built-in can preserve cabinet space, but it still needs a suitable permanent opening and connections. A 24-inch model may fit a standard dishwasher bay, though checking the listed dimensions is safer than relying on the category label. Countertop machines can avoid a cabinet installation, but they occupy worktop space and may need access to a faucet or a separate tank. Before buying, check how the specific model fills and drains, because “portable” does not describe one universal setup. A common mistake is choosing by width alone and overlooking the space needed to load the machine or route its hoses.
Match Capacity to Your Dish Routine
Place-setting counts offer a starting point, but they do not show how well a rack handles your actual plates, pans, mugs, and utensils. Think about how often you cook and whether large cookware will go in the dishwasher or be washed by hand. Compact countertop units can work well for one or two people who run smaller, more frequent loads. A household that cooks daily may find that a slimline machine fills quickly, even when its advertised capacity seems adequate. Check rack layout and interior measurements when available, especially if you use oversized plates or tall glasses. Buying too much capacity can waste space in a small kitchen; buying too little can turn dishwashing into a daily bottleneck.
Separate Wash Features From Drying Needs
Wash programs help address different soil levels and load types, but the number of cycles alone does not tell you which will be useful. Consider whether you mostly need a reliable everyday cycle or would use options such as a delayed start or a more specialized wash. Drying deserves its own check: some models specifically list heated dry or air-dry functions, while other descriptions may not state a drying method. If you put dishes away soon after a cycle, drying performance may matter more than extra program choices. If you are comfortable air-drying plastics or leaving the door open, you may accept a simpler drying setup. Read the product specifications for the exact model rather than assuming that similar-looking versions share the same functions.
Plan for Water, Drainage, and Installation
Built-in dishwashers need a suitable water line, drain connection, and electrical supply, so include installation needs in your decision before choosing a model. A countertop machine may connect at the sink or draw water from an included tank, depending on its configuration. Tank operation can be useful where faucet access is awkward, but remember that filling and emptying still take time and attention. Confirm whether the drain hose can reach an appropriate sink or drain without creating a spill or trip hazard. Renters should check building rules and their own willingness to connect and disconnect the appliance. The common mistake is treating a small appliance as connection-free simply because it is portable.
Think About Noise, Care, and Ownership
Noise can matter in a studio or open-plan home, so use a published decibel figure when one is available and compare it with the other details for that same model. The listed 40 dB figure on one EUHOMY countertop option gives buyers a concrete point of comparison, while many product names provide no noise figure. Filters, spray arms, seals, and the interior need routine care, so check the manual for cleaning guidance and accessible replacement parts. A stainless steel tub may appeal to buyers weighing interior material, but it does not remove the need for upkeep. Confirm warranty coverage, service availability, and installation requirements before committing. Those ownership details can matter more over time than an extra wash program.
Set Priorities Before Comparing Similar Models
Several entries share a brand or broad format, so write down the feature that would change your decision before comparing model names. For COMFEE’, that could mean choosing between a built-in installation and portable countertop use, or between a tank-equipped description and a model listing more wash programs. For full-width machines, compare the stated tub material, drying function, place settings, and controls rather than assuming one is automatically the premium choice. Product descriptions may omit details, and an unlisted feature should not be treated as included. Check the current manual and seller specifications for dimensions, hookups, and included accessories. This short check can prevent paying for a configuration that does not work in your home.
Frequently Asked Questions
Can a countertop dishwasher handle the dishes from a small household?
It can, if your household produces modest loads and you are comfortable running the machine more often. Compare the listed place settings with the cookware you use, since pans and large plates can take up room quickly. A countertop format also uses worktop space and may need a faucet connection or manual tank filling. If you cook frequently or want to wash several meals’ dishes at once, an 18-inch built-in may be a better fit. The right choice depends on your dish volume as much as the number of people at home.
Should I choose an 18-inch built-in or a 24-inch model?
Start with your cabinet opening and installation options, then consider how often you run full loads. An 18-inch model can preserve kitchen space and suit a smaller household, but its narrower interior may fill sooner. A 24-inch model typically occupies a wider appliance bay and may suit people who want to collect more dishes between cycles. Dimensions and rack layout vary, so check the exact model rather than relying on width alone. If your kitchen has no compatible opening or plumbing, a countertop unit may be more practical than either built-in size.
Do portable countertop dishwashers always need a faucet connection?
No. Some countertop models are described with an onboard water tank, while others may rely on a sink connection; check the individual product instructions. A tank can help when a faucet adapter is inconvenient, but you need to fill it for each load and plan how the machine drains. A faucet-connected setup can reduce manual filling, though the connection must fit your tap and be accessible during use. Measure the hose route and available counter space before buying. “Portable” alone does not tell you which water setup a model uses.
Is a stainless steel tub worth prioritizing?
A stainless steel tub may be a meaningful preference if interior material is high on your list, and several slimline options here specifically list one. Still, tub material does not tell you how well a dishwasher fits your dishes, dries a load, or connects in your kitchen. Compare it alongside capacity, cycle details, drying features, and care requirements. Some models in the roundup list a hybrid tub instead, so read the precise configuration if material matters to you. Choose the material as one factor in the decision rather than a substitute for checking the whole appliance.
What should I verify before ordering a built-in dishwasher?
Measure the cabinet opening, appliance depth, and door clearance, and check the specified water, drain, and electrical connections. Confirm whether the model’s handle and controls suit your kitchen layout and whether its finish fits your space. Check the rack dimensions against your plates, glasses, and cookware, since a nominal place-setting count does not capture every load. Review the installation instructions and warranty before arranging delivery or fitting. That preparation is especially useful when comparing 18-inch models with a standard 24-inch opening.
Conclusion
For a best overall choice, I would start with the Honeywell 18-inch built-in if your kitchen supports a slim permanent installation. The Midea 18-inch built-in is a value-minded option to compare when its listed eight-place-setting capacity fits your household, while the Cosmo makes sense for shoppers who prefer a full-width top-control tall-tub design. For a best premium-style feature set among these entries, the Sharp lists heated dry and 12 place settings, though its hybrid tub and stated noise level may not suit every buyer. Beginners who want a smaller appliance can start with a COMFEE’ countertop model after checking its water connection and drying setup. For renters or kitchens without a built-in opening, compare the portable COMFEE’, BLACK+DECKER, SPT, and EUHOMY options by tank or faucet setup, capacity, and available counter space. My final pick depends on your kitchen first: choose the format that fits, then compare the features you will use.
