How Much Water Does A Dishwasher Use?

No one would judge you for assuming that a dishwasher uses a considerable amount of water with each load. After all, it's typically one of the largest appliances in your home. You've probably wondered: do dishwashers save water, or do dishwashers use a lot of water? It depends on the make and model of your machine, but many newer dishwashers are more efficient than you might think.


Of course, a modern, Energy Star-rated dishwasher is going to be far more efficient than an older model. In fact, dishwashers manufactured before 1994 can use as much as approximately 9-14 gallons of water per load.1


However, new standard-sized dishwashers use, on average, 3 gallons of water per cycle. They are designed to only use and heat the exact amount of water they need to clean dishes effectively. Washing up the same number of plates by hand could see as much as 13 gallons of water literally poured down the drain!2


How to save water when using your dishwasher

Not only are newer dishwashers more efficient with their water usage, you can also use them in ways that will further conserve water. These tips can help to reduce your water bill and ensure your dishwasher has a long life of producing sparkling clean dishes.


Water-Saving Tips


1. Save water by skipping the pre-clean rinse in the sink.

2. Avoid multiple cycles per day by waiting until you have a full load.

3. Ensure the inside of your dishwasher is clean and that the arm sprayer isn’t hindered by obstacles. This will eliminate the need to run multiple dishwasher cycles.

4. Choose an eco-setting, which will use less energy by washing your dishes at a lower temperature and use less water during each cycle.

5. Use a quality detergent like Finish® Quantum® to ensure your dishes come out clean the first time, every time.
