Saving Energy with your commercial dishwasher

In busy kitchens, dishwashers can be running all day every day with little break. While this can save owners and staff time there is once concern that they often voice…how much energy is it actually using? Well this of course depends on the individual dishwasher and the heat settings that you have it on but there are a few simple tips that you can follow to cut down on your energy consumption and bills.


When we talk about industrial dishwashers actually using energy, the majority of what we talk about is used for heating the water to wash the dishes. Be sure to check your energy guide label for specific manufacturer information on power consumption and then use this to calculate actually how much you’re spending depending on your gas and electric prices.

How can a save energy with my dishwasher?

The key to saving energy with your commercial dishwasher is making sure that you use as little hot water as possible, below is a few tips on how to achieve this:

  • First, consult the manual that will have been supplied when you received your washer, in here are usually hand tips on the recommended washing temperatures for certain dishes. It’s possible that you’re using a higher temperature than your needs require, thereby wasting energy and money. Many washers come equipped with variable temperature heating elements meaning that you can turn the heat up and down as required.
  • If you can, cut down on pre-washing. This can be done by ensuring that your dishes are reasonably clean before they go in the washer. Be sure to scrape off any large pieces of food etc. Only use the ‘pre-wash’ option if you have particularly stubborn substances on your plates that have perhaps been burned on etc.
  • Do not over-load your dishwasher when it comes time to run it.
  • Most washing machines come with the option to ‘rinse and hold’, this should be avoided especially if you’re only washing a small number of dishes due to the fact that this setting can use as much as seven gallons of water for each cycle.
  • If possible and time permits you to do so, allow your dishes to dry in the air rather using the heated dry setting that is usually default on dishwashers. If your washer doesn’t come with the ability to allow you to do this, then you may have to switch it off manually to prevent this from happening.
