Energy Savings for Your Dishwasher


Studies show more and more that modern dishwashers with energy saving features can outperform all but the most frugal hand washers.
Try these tips to maximize the dishwasher’s energy savings:

  • Wash When Full: The dishwasher uses the same amount of water whether it’s half-full or completely full, so wash more dishes to prevent wasting water and energy. If you find that it takes a day or two to get a full load, use the rinse and hold feature to prevent buildup of dried-on food. The rinse feature typically uses only 1 to 2 gallons of water.
  • Use Efficient Settings: Pay attention to the cycle options on your dishwasher and select the cycle that requires the least amount of energy for the job. Avoid settings such as pots and pans or anti-bacterial options, as the cycle runs longer using more hot water and energy. Use the no-heat air-dry feature on your dishwasher if it has one, or prop open the dishwasher door to let the dishes air dry.
  • Scrape Dishes: Soaking or prewashing is generally only recommended in cases of burned-on or dried-on food.
