Dishwashers: what they cost to run
A dishwasher's cost accrues per load, so the DOE certification bakes in a standard year of cycles (215). On that basis the 677 certified models here cost between $15 and $45 a year at the U.S. average rate — median $45.
Most of a dishwasher's energy goes into heating water, so water-per-cycle and the drying method (heated vs. air/condensation) separate the efficient from the expensive. Every figure on this page comes from ENERGY STAR's certified test data — the 80–240 kWh/yr range you see is measured, not estimated.
