Our take: do not pay for an assumed performance gap
These are close alternatives for a reader who can use a faucet connection and has room for a wider countertop machine. Both are described as six-place-setting models. More revealingly, their manuals list the same Normal-cycle time, energy and water figures.
Choose between the exact offers after confirming fit and setup. Our evidence does not justify naming one the better cleaner or the more reliable machine. A suitable layout, the seller’s terms and a feature you will actually use are more defensible deciding factors.
Choose neither if tank filling is essential. The HAVA and COMFEE tank-model comparison addresses that different need.
| Manual or listing detail | Danby DDW631SDB | COMFEE CDC22P2AWW |
|---|---|---|
| Supply arrangement | Faucet quick-connect | Faucet quick-connect |
| Normal program: time | 110 minutes | 110 minutes |
| Normal program: energy / water | 0.36 kWh / 10.8 liters | 0.36 kWh / 10.8 liters |
| Speed program | 45 minutes | 45 minutes |
| Dimension evidence | Brand: 17.25 H × 21.65 W × 20.65 D inches | Manual: 17¼ H × 21⅝ W × 19 11/16 D inches; brand depth differs |
Program figures are from the manuals’ printed page 9 tables, not household measurements. Equal published values do not prove equal real-world performance.
What matching cycle tables mean for your budget
If you enter the same utility rates, detergent allowance and number of Normal cycles, the documented inputs produce the same running-cost example. There is no basis in those inputs for declaring a large energy-cost advantage for either model.
Our running-cost calculator uses those Normal-program figures for an illustration. Purchase price, setup, inlet-water heating, repairs and other exclusions still need considering. Check the current offer at the retailer rather than relying on a price copied into an article.
The depth discrepancy can matter more than the brand
COMFEE’s linked manual gives a 500 mm / 19 11/16-inch depth, while its product page lists 20.6 inches in the dimension set. That is a material difference beside a short counter. We cannot resolve it by choosing whichever figure makes the machine fit.
Danby’s own page lists a 20.65-inch depth. Treat both products’ body dimensions as the start of installation planning: you also need a workable connection and an open-door loading path. Ask for the current exact-model drawing when the available space is close.
Will the faucet arrangement work for you?
Both manuals describe a quick-connect assembly. Neither is a way around a faucet manufacturer’s restriction. For example, Delta’s published answer excludes its pull-down and pull-out faucets. The compatibility guide explains that case and offers tank alternatives.
For a suitable fixed faucet, picture the whole routine: start a wash, prepare a drink, clear food from the counter, then unload. A larger tableware capacity is useful only if the appliance and its hoses do not make that routine awkward.
Which one belongs on your counter?
The manuals do not establish a cleaning or reliability winner. Once both fit, compare the actual offers on equal purchase terms.
Danby DDW631SDB
Shortlist it when: a faucet-fed, wider machine suits your kitchen and the exact offer meets your needs.
Resolve first: tap compatibility, installed depth and the dishes you want it to take over.

COMFEE CDC22P2AWW
Shortlist it when: its documented setup fits and its seller, delivery and return terms suit you.
Resolve first: the manual-versus-listing depth discrepancy before relying on a tight counter space.

Why Danby’s water figures need a qualification
The Danby manual’s Normal-program table lists 10.8 liters and 0.36 kWh. Danby’s product page instead states 11.7 liters / 3.1 US gallons. We cannot establish the reason for that difference. These are published figures, not our household measurements.
Use the manual value as an explicit calculation assumption, not an exact forecast. The difference is 0.9 liter per wash: about 4.76 US gallons over 20 cycles. At $10 per 1,000 gallons, that changes the water-and-sewer example by roughly five cents a month. Electricity, detergent and the number of loads remain separate inputs.
