What Would Happen If the Dishwasher is Run Without Water?

A dishwasher has a pump and a heating element which would get damaged if you don’t use water while running the dishwasher. Also, it would get “stalled” when you try to turn it on the next time. 

This wouldn’t cause permanent and heavy damage, but if you keep using the dishwasher without water, it might lead to that. An excellent electrical appliance works for ages if you use it correctly, and a dishwasher is no different.

The reason behind this is that water is a big part of the whole cleaning process. You cannot clean your dirty dishes without water. The dishwasher is made in such a way that it does not work without the presence of water.

Is It Bad for a Dishwasher to Run Without Water?

Yes, it is harmful to a dishwasher to run without water. Let us now understand what happens to the main working parts of the dishwasher when you run it without water. 

  • Dishwasher’s Heating ElementThe heating elements would gradually become poor as you keep running the dishwasher without water.
  • Pumpthe quality of the pump would degrade if you run the pump without water since there is a high surge of power through it, and without water, it would just damage the pump.

The quality of the dishwasher would gradually degrade with such a bad practice. It will age fast and live up to its full potential. Also, electricity would be wasted because of such a practice. Using more electricity would lead to a very high electricity bill. This is precisely why the machine has to be used carefully.

Can You Use a Dishwasher With Low-Pressure Water?

A dishwasher would run with low-pressure water. However, it might not be able to clean the dishes quickly. High water pressure ensures that dishes are cleaned to their absolute roots.

However, nowadays, technology has advanced so that dishwashers use low water pressure to clean as they also promote a healthy, sustainable environment. Whereas, if you are using an older version of the model, it still might need high-pressure water to clean the dishes.

Can a Dishwasher Run Without Hot or Cold Water?

A dishwasher would also work well without hot water, as it doesn’t need hot water since it already comes with a heating element. The element takes up the cold water and heats it to around 120 °F.

When it gets heated up, it gets taken up by the machine itself, and then the temperature is further raised to about 140 °F to 150 °F to clean it better.

Dishwashers usually use hot water for cleaning as it does a better job. They are purposely connected to the hot water supply so the dishwashers can use the hottest temperature to clean the utensils best.

But if you use cold water, the heating element would use more electricity to heat the water, leading to a costly electricity bill. This is why it is not advisable to use cold water as more electricity would get used up. It is also not a sustainable habit if you consider the environmental implications.

Half a cup of water in the bottom of the dishwasher can be considered normal. But if you still feel something is wrong, you can take professional advice from a plumber.

Q4. Should you run the dishwasher without water as a test?

You must test a new one when you buy it first to check if it’s in working condition. However, you will need water to check for a stable water connection. Therefore, it is advisable to run it with water at least.


Dishwashers are the boon of technology and have done nothing but serve this humankind by minimizing efforts. Therefore, the bad conduct of dishwashers would not only degrade the dishwasher’s quality but also become an expensive ordeal for you.

If you wish to sustain your dishwasher for a more extended period, have a stable water connection and remember how you use it. Keep healthy practices as it will ensure longevity.
