Maytag MHW6630H
Across a standard year of loads (234 cycles under the DOE test), the Maytag MHW6630H uses 143 kWh — about $26 at the U.S. average electricity rate, or roughly 11¢ per load. It sits near the bottom of the certified table — using 30% more than the median clothes washer (rank 271 of 344) — so the state you live in matters more than usual. The same unit costs $19 a year in Nevada but $75 in Hawaii — electricity rates, not the appliance, make the difference.
