What Stands Out

  1. 6-place-setting capacity with a dedicated silverware basket, in a 19.69"D x 21.65"W x 17.24"H footprint
  2. Eight wash cycles, including Intensive, Normal, Economy, Rapid, Glass, and Soak, plus Baby Bottle and Rinse settings
  3. Quick-connect faucet hookup works with most kitchen faucets — no manual water filling or built-in tank required

Strengths and Drawbacks

What works

  • 6-place-setting capacity accommodates a complete dinner service for a small family in a compact footprint
  • Energy Star certified operation using up to 3.1 gallons of water per cycle, a real saving over washing by hand
  • Quick-connect faucet hookup gets the unit running without permanent plumbing work, and setup is fast and easy
  • Eight wash cycles, including Intensive, Economy, Glass, and a dedicated Baby Bottle setting, cover most everyday loads
  • 54 dB operation is unobtrusive during daytime cycles
  • Stainless steel interior holds up well, with years of use and no mechanical issues

What does not

  • No heated drying element, so some dishes need air-drying time after the cycle finishes
  • The quick-connect hookup can be hard to fit on older or nonstandard kitchen faucets

Features in Depth

01

Eight Wash Cycles and a Delay Start

Wash Cycles 8, including Intensive, Rapid and Soak Water Consumption Up to 3.1 gal (11.7L) per wash Delay Start 2, 4, 6, or 8 hours

Danby quotes eight wash cycles, among them Intensive, Normal, Economy, Rapid, Glass and Soak, and a delay-start option of 2, 4, 6 or 8 hours suggests a machine built around running unattended overnight or before you get home. On the water side, it uses up to 3.1 gallons (11.7L) per wash and is Energy Star compliant, a low per-cycle figure for a dishwasher. Cleaning is a real strength, good enough to rival full-size models, and even the Eco setting handles stuck-on food without trouble over years of use. Overloading is the thing to avoid: dishes can come out dirty when the rack is packed too tightly for the water to reach.

Countertop Footprint with Quick-Connect Faucet Hookup and 6-Place Capacity

Capacity 6 place settings + silverware basket Product Dimensions 19.69"D x 21.65"W x 17.24"H Item Weight 44.1 lbs

This is a countertop unit, not a built-in. Danby's quick-connect feature hooks it up to most kitchen faucets, so it runs off your existing tap rather than needing plumbing work, and setup is easy, taking about two minutes of screwing on the faucet adapter and hoses. It measures 19.69 inches deep by 21.65 inches wide by 17.24 inches tall, weighs 44.1 pounds and has a 4.92-foot cable, so check it against your own counter space and outlet placement before buying, since a unit this size needs a stable footprint and faucet clearance. Capacity is 6 place settings with a dedicated silverware basket, which suits a small household: a family of three can rely on it for years, two people in a small apartment can run it once a day with plenty of room, and a single person may need only about a load a week, more when cooking for company. Bulky items are the variable: a casserole and pots can fit alongside a full load, yet a single large pot or pan can also take up a lot of the rack. Fit and size are its weak points, mostly with older or nonstandard faucets and tighter layouts, and plumber's tape on the hose connections helps, tightened with a wrench but not overtightened.

03

54-Decibel Operation with a Full-Panel LED Display

Noise Level 54 dB Controls Full Panel, LED Display Voltage 120 V

Danby rates it at 54 decibels and describes this version as quieter than before. For context on what that number means in practice: a quiet conversation typically sits somewhere in the 50-60 decibel range, so a countertop dishwasher rated at 54 dB is operating closer to background-conversation volume than to anything disruptive, which matters more for this form factor than for a full-size built-in, since a countertop unit runs in the open room rather than sealed behind cabinetry. In daily use it is quiet enough not to intrude. Controls are handled through a full panel with an LED display, rather than a simpler dial or button-only interface, and it is easy to use as a result, since a legible LED readout paired with cycle and delay-start selection reduces the guesswork that comes with unmarked dial positions. The unit runs on a standard 120-volt household circuit, so no special electrical work is implied by the control panel or the display itself.

04

Long-Term Reliability and a 1-Year In-Home Warranty

Long-Term Use 3 to 4+ years of service Drying No heated dry Warranty 1 year parts and labor, in-home service

Danby backs the unit with 1 year of parts-and-labor in-home service, which covers the most likely early failure points without requiring you to ship the unit anywhere. The appliance tends to hold up well past that first year: daily use nearly 3 years in, more than 4 years of weekly loads without a mechanical issue, and 3 trouble-free years in a hard-water home with a descaler run through it periodically. That longevity is what makes it good value. Not every setup is that smooth, though, and in an older kitchen or with a nonstandard faucet, check the fit before assuming an easy install. It also has no heater for drying, which is worth knowing if you expect fully dry dishes at the end of a cycle.

How We Scored It

Based on
The manufacturer's published specifications and the product's live Amazon listing.
Owner rating
4.1 out of 5 on Amazon, recorded September 26, 2026
How we score
We score each thing that comes up most in owner feedback on the Danby DDW631SDB Countertop Dishwasher. Eight things come up most in owner feedback: six draw praise and two split opinion. Its ratings average 4.1 stars (62% five stars, 17% four, 5% three and 16% one or two), so every score starts at 82, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read nine owner reviews in full (every one we found gave it four or five stars) and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.1 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Nothing comes off here, so it stays at 4.1. Read our editorial standards

Setting It Up

  1. Unpack and Position Unit

    Remove all packaging materials including foam inserts and protective tape. Place the dishwasher on a level countertop with some clearance around it for ventilation, close enough to the sink for the drain hose to reach. Check that it sits level so the door closes squarely.

  2. Connect Power Supply

    Plug the power cord (4.92 feet) into a grounded 120V outlet without an extension cord. Use a dedicated circuit where possible rather than sharing with other high-draw appliances.

  3. Connect the Faucet Adapter

    Attach the included inlet hose to your kitchen faucet using the quick-connect adapter, then route the hose to the rear inlet port and tighten the connection, with plumber's tape on the threads. Check your faucet type before ordering, since the fit can be trickier on older or nonstandard faucets.

  4. Position Drain Hose

    Extend drain hose from rear port and secure the end over the sink edge. Ensure the hose runs downhill into the sink without kinks or loops that restrict water flow, so it drains properly.

  5. Load Dishes and Add Detergent

    Arrange dishes with plates facing inward toward the spray arm and glasses and cups upside-down. Load utensils in the basket with handles down. Add powder or liquid detergent to the dispenser cup; a compact dishwasher needs less than a full-size one, and regular dish soap creates excessive suds.

  6. Select Cycle and Start

    Press Power to activate the control panel. Select the wash program you want (Heavy, Normal, ECO, Glass, Rapid, Soak, Baby Bottle or Rinse). Press Start/Pause and close the door. The LED display shows the cycle's progress.

Common Questions

How many wash cycles does the DDW631SDB actually have, and what are they called?

Danby quotes eight wash cycles and names Intensive, Normal, Economy, Rapid, Glass and Soak among them, with a delay start of 2, 4, 6 or 8 hours on top. In practice, the Eco setting handles everyday loads without trouble from stuck-on food, and a 20-minute Party Cycle is worth trying for a quick wash.

Will this fit my kitchen faucet and countertop?

Danby describes a 'quick connect feature compatible with most kitchen faucets,' and the unit measures 19.69"D x 21.65"W x 17.24"H at 44.1 lbs with a 4.92-foot cable - worth measuring against your own counter and outlet before ordering. Fit and size are its most common stumbling blocks, usually with older faucets and tight counters, so check both; most kitchens, older apartments included, manage it without trouble, and a poor fit is the exception rather than the norm.

How much water does it use compared to a full-size dishwasher?

Danby specifies up to 3.1 gallons (11.7L) of water per wash, and the unit is Energy Star compliant. That's a low per-cycle figure by dishwasher standards generally, and it cleans well enough to rival full-size models while using very little water.

Is the DDW631SDB noisy when running?

Danby rates it at 54 decibels. That's roughly in the range of a quiet conversation, and in practice it is quiet, which matters for a countertop unit specifically, since it sits out in the open kitchen rather than sealed behind cabinetry like a built-in model. Controls run through a full panel with an LED display, and it is easy to use too, so it is both quiet and easy to follow, with a legible readout for tracking which cycle and delay setting is active.

How many place settings does it hold, and is it enough for a small household?

Danby specifies 6 place settings plus a dedicated silverware basket, and that suits a small household. A family of three can rely on it for years, two people in a small apartment can run it once a day with plenty of room, and a single person may run only about a load a week, more when cooking for company. Bulky items vary: a casserole and pots can fit alongside a load, but a single large pot or pan can take up a lot of space. Treat 6 place settings as the planning figure.

Is it reliable, and what's covered under warranty?

Danby covers it with 1 year of parts-and-labor in-home service. It tends to last, with units still running nearly 3 years and more than 4 years after purchase, which makes it good value. Not every install is that smooth, though, and fit and size are its weak points, so check your faucet and counter space before ordering.

The Verdict

4.1Out of 5

Its eight wash cycles and Energy Star certification make it a strong pick for apartment dwellers and small households who want consistent results without a plumbing installation. The quick-connect hookup works with most kitchen faucets, and 54 dB operation keeps it unobtrusive in shared living situations. Set against simpler budget alternatives, the Danby's water efficiency and stainless steel construction make the case for spending more if you prioritize long-term reliability over the lowest sticker price.

Who should buy it

  • Apartment and condo renters
  • RV and tiny-home owners who want a genuinely compact unit that still connects to a standard kitchen faucet
  • Small households of 1-3 people generating a daily load who value Energy Star efficiency and low water use
  • Environmentally conscious users prioritizing 3.1-gallon-per-cycle consumption over the fastest possible cycle speed
  • Shared-wall residents who want quiet, 54 dB daytime operation that won't disturb neighbors
  • Buyers willing to accept some air-drying time in exchange for stronger water efficiency and stainless steel durability than simpler budget models offer

The Danby DDW631SDB earns its recommendation as a reliable countertop dishwasher that prioritizes water efficiency and cleaning consistency over rapid cycle times and heated drying. Its eight specialized wash cycles, low per-cycle water consumption, and quick-connect faucet installation deliver practical value for small households and space-constrained living situations. The trade-off is drying performance and cycle length: without a heated-dry element, plan on some air-drying time, and expect cycles that favor thoroughness over speed. The Energy Star certification and stainless steel durability make this a balanced mid-range choice for buyers who want dependable results without plumbing modifications.
