The water usage of a dishwasher can vary depending on the make and model, as well as the specific settings chosen. However, on average, a typical dishwasher cycle uses around 6-10 gallons (22-38 liters) of water. Some energy-efficient models may use less water, while older or less efficient models may use more. It's always a good idea to refer to the manufacturer's specifications or user manual for the specific water usage of your dishwasher model.
