So, when you’re examining the water-efficiency the a dishwasher, a general rule-of-thumb is the dishwashers built after might of 2013 are much more efficient than dishwashers built before that date.

Before DOE collection this new standard, water usage varied significantly. Ago then, the mean dishwasher used 10 gallons per cycle, however some wasted also more.

Dishwasher Cycle
