Your dishwasher uses about 7 gallons of water per wash, with prewash, or about 3 1/2 minutes of running your kitchen faucet. With a sanitizing (added heat) cycle, it gets the water much hotter (usually >165° F) than what comes out of your faucet. Plus, you don’t have to stand hunched over the sink washing dishes.
