How to lower the cost of running a dishwasher

Most of a dishwasher's electricity goes into heating water and running the heated-dry cycle; the pump and motor use comparatively little. A typical load uses around 1–2 kWh. ENERGY STAR models and eco cycles use less water and lower temperatures, and skipping heated dry can save around 15% per load. Running a full dishwasher generally uses less energy and water than washing the same dishes by hand.

  • Only run it when it's full, and use the eco or energy-saver cycle.
  • Turn off heated dry and let dishes air-dry with the door cracked open.
  • Scrape instead of pre-rinsing under hot water.
