Space-Saving Build

The Danby measures in at 22 inches wide and 17 inches deep while standing a mere 20 inches tall. Overall, it’s safe to say that finding a space on your countertop for this Danby dishwasher is not going to be a challenge. In fact, you may notice that most, if not all, modern countertop dishwashers take up roughly the same amount of space—the Supentown SD-2224DS included. However, their compact size does not limit how many dishes they can clean in one cycle.

Wash Capacity

This countertop dishwasher can fit up to six place settings at once with plates of up to 10.5 inches in diameter. The large interior makes this ideal for small families who don’t want to spend a fortune on permanent, floorspace-taking dishwashers. The Supentown’s interior can also fit the same exact amount of place settings at once.

6 Wash Cycles

The Danby comes with six different finely-tuned wash cycles for each of your needs. These include soak, glass, rapid, economy, normal, and intensive wash cycles. These different wash modes and cycles allow you to as little or as many dishes as you want while using the minimal amount of water and electricity.

52-decibel Noise Output

Dishwashers are notorious for being loud, but modern countertop dishwashers are built with better soundproofing technology. At most, the Danby generates a 52-decibel hum while washing your plates—about the same noise output as a microwave. Needless to say, this is far from being deafening.

Electric Controls with LED Display

One of the handier features of the Danby, and the Supentown as well, is its LED display. The display shows you the selected wash cycle and delayed start option of up to eight hours. It’s pretty basic so you won’t know how many minutes are left before the cycle is completed, but an abrupt stop in humming and spraying water should be a clear indication of that.

Supentown SD-2224DS

Stainless-Steel Interior

Both the Supentown and Danby come with a stainless-steel interior and different racks and shelves for your plates, cutlery, and cups. The stainless-steel design is corrosion-free throughout its lifespan, though you may need to decalcify the interior every couple of months.

7 Wash Cycles

The Supentown’s wash cycle count is one more than the Danby’s. It has soak, speed, rinse, mini party, light, normal, and intensive washing that are tailored for a specific number of items to ensure maximum water and energy efficiency. It’s missing a wash mode for delicate glassware, but its light wash cycle should do the trick.

Warning Indicators

There are two warning lights found on the Supentown. The first is a water indicator that lights up when your faucet is turned off. The second indicates that the rinse aid needs to be refilled. The machine will automatically put its wash cycle on pause when either of these lights are activated. The Danby, as you may have guessed, also has these features.

Plug-and-Play Installation

Like any countertop dishwasher, the Supentown (and Danby) is a plug-and-play kitchen appliance. It comes with two universal hoses—one for water intake from a faucet and another that runs into the sink to drain—which require no external tools to set up. In less than 30 minutes, your new countertop dishwasher can be fully prepared to begin its first wash cycle.

Delayed Start

If you don’t plan on starting the wash cycle right away, the Supentown offers a programmable delay for two, four, or eight hours. When the countdown expired, if the door is closed properly, the Supentown will begin asking for water from the faucet to prepare the washing and rinsing. This handy set-it-and-forget-it feature will help take the load off of needing to manually select a wash cycle every time.

Danby vs. Supenton: Which Countertop Dishwasher Should I Get?

Apart from their obvious difference in appearance, there’s really not much discrepancy between the Danby DDW621WDB and the Sunpentown SD-2224DS. Even the “missing” glassware cycle in the Supentown is replaced by the light wash cycle, and both machines have rapid and economy modes to save on water and energy.
