- DO wash full loads. The dishwasher uses the same amount of water whether it’s full or half-empty, so it’s more efficient to wait for a full load. Doing so can save you 400 gallons of water per month.
- DON’T pre-rinse dishes. Scrape them instead. The water used to rinse dishes adds up – as much as 20 gallons per load. Most dishwashers can easily handle soiled items.
- DO dry dishes without heat. Select the dishwasher’s air-dry setting or open the door and extend the racks fully. This can cut energy use by 15 to 50 percent.
- DON’T use a dishwasher made before 1994. Replace it with an ENERGY STAR® model, which uses 1,000 fewer gallons of water per year than other models.
- DO load it correctly. Face the dirty side of plates and pans toward the inside of the machine, so they’re hit directly by water. Place large items at the back of the machine or they’ll block water and detergent from reaching other dishes.
