Fill it up: Washing full loads will reduce the amount of energy and water required to clean your dishes. One full load costs less to run than two smaller loads.
Dry them for free: Use the air dry function on your dishwasher.
Skip the pre-rinse: Don’t use the pre-rinse cycle on your dishwasher. It is not necessary with today’s dishwashers. Skipping it can save as much as 20 gallons per load or 6,500 gallons/year.
New Dishwasher: Is your dishwasher more than 10 years old? Replacing it with an ENERGY STAR model will save you energy and water since ENERGY-STAR-rated models use at least 40% less energy than the federal minimum standard for energy consumption and a third less water.
