Dishwashers Save on Energy and Money

According to a recent survey by the U.S Energy Information Administration around 20% of Americans aren’t using their dishwasher. If you fall in that 20% you are wasting a lot of money.


Some people have a misconception that dishwashers use more water than hand washing dishes in the sink. This is false! If you wash your dishes by hand, you’re wasting water, time and your dishes aren’t really getting clean.

In fact, you shouldn’t even pre-rinse your dishes — the dishwasher will do it for you much more efficiently.

Dishwasher vs. hand washing

How much can you really save by using your dishwasher? If you have an energy-efficient appliance, you can expect to, cut your utility bills by more than $40 per year, improve the cleanliness of your dishes due to the fact that dishwashers heat water up to 140 degrees, way hotter than our hands can handle — and our sponges are dirtier than a toilet seat. Save nearly 5,000 gallons of water a year

You have a dishwasher for a reason.

When you wash dishes by hand, you probably use lukewarm water so you don’t burn your hands off. When you do that, you aren’t really cleaning much. Our hands can’t take the heat at 140 to 145 degrees , which is required to truly clean dishes to the point of being bacteria free.

When it comes to loading the dishwasher, follow these tips:

  • Read the manual for tips specific to your dishwasher’s model. Really, this is important, since the setup of racks and location of water jets differs across brands and models.

  • Glasses go on the prongs, which tilts them at an angle and keeps water out of many glasses with concave bases.

  • Scrape big food chunks off, but don’t pre-rinse. Wastes water.

  • Instead of pre-rinsing, run the water in your kitchen faucet until it becomes hot before starting the dishwasher, to make sure the water doesn’t start flowing in while cold.

  • Put the heaviest and most soiled items on the bottom rack, keeping them in range of the spray arm. Arrange pots, pans, and plates however your dishwasher’s manual tells you to. If you’re a renter and don’t have the manual, you may be able to find it on the manufacturer’s website, or from a third party somewhere online.
