Therefore, look for features that reduce water usage. Consider purchasing a dishwasher that uses fewer gallons during the different cycles since they will cost the least to operate. A lower setting will also reduce the danger of scalding. Also check to see if the dishwasher has an energy efficient no-heat drying cycle. It costs less to air dry dishes.
Compact models use less energy but hold fewer dishes.
A compact model may actually result in greater energy use if you have to operate it more frequently. Choose a dishwasher that has several wash cycle selections. Scrape instead of rinsing off large food pieces from the dishes. Soaking or pre washing is usually not necessary unless food is burned or dried on the dishes. It uses 3 to 7 gallons of hot water.
