Dishwasher vs Washing Machine: Which Costs More to Run? (2026)

These are not alternatives but people often ask which costs more to run. Per cycle they are similar at 1 to 1.5 kWh for a normal program, because both spend most of their energy heating water. The washing machine has far more headroom for savings: a cold wash drops its energy by up to 90 percent, while a dishwasher must heat water to clean.

At the hours shown, Dishwasher costs about $100.41 a year and Washing Machine about $33.47 in the US.

When the dishwasher makes sense

  • Run it full and on eco, then it costs about the same as a cold wash
  • Skip heated drying to cut a third of the cycle energy
  • Do not pre-rinse under hot water

When the washing machine makes sense

  • Wash at 30 C or cold to make it the cheapest appliance in the house
  • Spin faster to save on drying
  • Always run full loads
