How we calculate this

Annual energy use (220 kWh a year) is the figure the manufacturer filed for this model with the U.S. Department of Energy, in the compliance certification database. Running cost is that figure multiplied by a state's average residential electricity price from the U.S. Energy Information Administration (12-month average through July 2026, average revenue per kWh).

The annual figure for a dishwasher assumes 215 cycles a year under Appendix C1, or 184 under the newer Appendix C2, per the DOE test procedure (10 CFR 430 Subpart B, §430.23(bb)). Full methodology.
