Dishwasher - Water Usage on Older Models

Modern dishwashers will adapt the water amount used within the cycle and from load to load, so the actual water consumption will vary. Water usage will vary based on the turbidity (soil level) detected in the dishwasher. Newer dishwashers are very energy efficient and some have an Energy Star rating.

This article documents the water usage in gallons for much older dishwasher models.
