Overview
The Danby DDW621WDB is a freestanding countertop dishwasher built for six place settings, with a stainless steel tub, a silverware basket, and a quick-connect hose that hooks to most kitchen faucets without permanent installation. It targets kitchens too small for a built-in unit.
Reviewers who've owned several older Danby countertop models say this one is noticeably quieter and cleans better than its DDW497 predecessor, though the redesigned side shelves sit higher and no longer leave room for a second row of short glasses underneath. It draws just 3.1 gallons per cycle and runs at about 52 decibels, quiet enough to hold a conversation over.
- 6 place settings with a dedicated silverware basket
- Energy Star rated, 3.1 gallons of water per wash
- 6 wash cycles selected via LED display
- Stainless steel interior tub
Who it's for
Best suited to apartment dwellers, single-person households, renters without a dishwasher hookup, or small secondary kitchens in an RV or tiny home. It is not a substitute for a full-size dishwasher if you regularly wash large stockpots or bulky bakeware.
What buyers say
From Amazon customer reviews.
Owners report the DDW621 cleans dishes spotless even with dried-on food left unrinsed, and several called it a real replacement for a full-size dishwasher on light to normal loads. The main complaint is the redesigned side shelves, set higher than on the older DDW497, which no longer leave room to fit short glasses underneath a second rack of cups. One buyer reported the unit stopped working within three weeks and described a frustrating experience with Danby customer service.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cleans effectively even on crusted, unrinsed dishes, per multiple reviewers
- Quieter operation than earlier Danby countertop models
- Simple faucet hookup with no permanent plumbing needed
- Delay-start scheduling up to 8 hours
- Side shelves sit too high for a second row of short glasses
- One reported failure within three weeks paired with a difficult customer service experience
- Single bottom spray arm only, no top sprayer
- Drain cycle can be noticeably loud
Performance notes
The unit connects to a kitchen faucet through a quick-connect adapter rather than a plumbed line, and an electronic LED panel controls six cycles: soak, glass, rapid, economy, normal, and intensive. A redesigned spray arm and filter handle the cleaning, and a delay start of 2, 4, 6, or 8 hours lets you schedule a wash for off-peak hours.
