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:
- Make sure you only run full racks, which can save you hundreds of dollars annually.
- 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.
- if the pressure gauge is reporting pressure above 25 psi you could be using more water
than necessary. Most dishwashing machines require 20 psi.
- Check water temperature and use manufacturer’s guidelines for tank and rinse temp.
- Make sure you operate conveyor dishwashing machines in auto mode, which saves electricity by running the
conveyor motor only when needed.
- 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.
