Question: how many gallons of water does a dishwasher use in a normal cycle?
Answer: National Energy Awareness Month is approaching, so it's a good time to remember that the energy use for a dishwasher is between 0.87-1.59 kWh per load, and the average dishwasher uses six gallons of water per cycle. More efficient dishwashers, Energy Star-rated dishwashers, use four gallons per cycle.
