The water usage of a dishwasher can vary depending on the specific model and its efficiency rating. However, on average, a standard dishwasher uses approximately 6-10 gallons (22-38 liters) of water per cycle. Keep in mind that newer, more energy-efficient models tend to use less water than older ones. It's always a good idea to refer to the manufacturer's specifications or user manual for the exact water usage of a particular dishwasher model.
