Maytag MDC4809PAB 24-in. Portable Dishwasher Review$749.00
We found the MDC4809PAB used between 0.6 and 1.07 kWh per cycle. A fairly average finding, this translates to electricity costs of roughly 6 to 11 cents per wash.
Water consumption was slightly higher, depending on the chosen cycle. (Of course, efficiency also depends on how hot you run your faucet during operation.) While the Normal wash’s command of just 3.91 gallons is pretty impressive for a standard cycle, the 1-Hour Wash used a slightly above-average 5.02 gallons of hot water. Including the Heavy wash’s consumption of 7.02 gallons, these figures averaged out to a water bill of about 4 to 7 cents per cycle.
Yearly Running Cost
The above efficiency data make for individual costs of 12 to 21 cents per cycle. Averaged through the course of a year—with the Normal cycle used 50 percent of the time—we found the Maytag MDC4809PAB will cost roughly $30.34 to operate.
