Specify ENERGY STAR® dishwashing machines!
Dishwashing machines are one of the most expensive pieces of equipment in the kitchen to operate. Purchase ENERGY STAR models that use less
water- one gallon or less of water per rack washed will save you significantly on water and electricity, as shown in the graphic below.
Consider a refrigerant heat recovery system if you have moderate to high hot water needs. Refrigerant heat recovery systems use waste heat from
the walk-in refrigerators and freezers to preheat water that can be used in the kitchen.
Operating Tips for Dishwashing Machines:
Full Racks - Make sure you only run full racks, which can save you hundreds of dollars annually.
Turn Off - Turn dishwashing machines off at night. High-temp dishwashing machines often have internal tank heaters and could
be wasting energy heating water you don’t need. Turn off booster heaters and dishwashing machine exhaust hoods as well.
Rinse Pressure - if the pressure gauge is reporting pressure above 25 psi you could be using more water
than necessary. Most dishwashing machines require 20 psi.
Water Temperature - Check water temperature and use manufacturer’s guidelines for tank and rinse temp.
Auto Mode - Make sure you operate conveyor dishwashing machines in auto mode, which saves electricity by running the
conveyor motor only when needed.
Maintenance - Add or maintain wash curtains- the plastic strips located on the ends of the conveyor
dishwashing machine that are responsible for capturing the heat inside the machine.
