How Hot Do Dishwashers Get When Operating?

You probably use a dishwasher on a regular basis. But do you really have any idea of how hot do dishwashers get when they operate?

In this post, KitchenLowCost will bring some information about this issue and hope you can get the proper answer.

How Dishwashers Usually Work?

Usually, after loading dirty dishes in the dishwasher, you pour the detergent in, select the wash cycle you need and turn the machine on. Then the process of an operating dishwasher will start like the followings:

  • Pump water into the machine
  • Heat water to the appropriate temperature
  • Automatically open the detergent dispenser at the right time
  • Shoot water through spray arms to clean the dishes
  • Drain dirty water
  • Spray water onto the dishes to rinse them
  • Drain water again
  • Heat the air inside the machine to dry the dishes (if you have selected this function in advance)

Why Do Dishwashers Get Hot?

The reason why dishwashers get so hot when operating is because they use hot water to do the cleaning.

To assure removing food junks on the dishes and activating dish soap or detergent, hot water is regarded to be more effective than cold water.

According to the World Health Organization, a dishwasher is able to kill bacteria when its temperature reaches at least 140 degrees Fahrenheit.

How Hot Do Dishwashers Get When Operating?

Most water heaters aren’t set to be this high. Thus, the heating element in the dishwasher comes in and helps raise the water temperature up to this bacteria-burning level.

Therefore, dishwashers usually operate at high temperature levels to boost the cleaning efficiency and to help kill bacteria.

However, not all kinds of bacteria will be killed at this temperature. For some kinds, water needs to reach its boiling point which is 100 degrees Celsius or 212 degrees Fahrenheit to be able to deal with germs.

But inside a dishwasher, reaching this temperature is almost impossible.

If you are so serious and strict about hygiene factors or worried about health threats, totally relying on dishwashers may not be a smart decision.

In the next section, we will share with you how hot do dishwashers get.

How Hot Do Dishwashers Get?

So how hot do dishwashers get in reality? Below are some questions relating to how hot do dishwashers get.

How Hot Does A Dishwasher Heating Element Get?

We all have already known that dishwashers have a kind of element to heat the temperature of water so that it’s eligible to do the cleaning. It is the heating element.

Heating element is usually designed to be at the bottom of the dishwasher. When the water is pumped into the machine, particularly in the bottom basin, heating element will do its job and make water hot.

A heating element is more than the heating alloy alone. It consists of a framework of insulating material as well as lead connectors.

Mica or ceramic insulators are used to hold or suspend the heating alloy in an open coil heater. The heater coils are safely connected to the circuit when using wire terminals.

In common appliances, heating elements are made from metallic resistance alloys such as Fe-Cr-Al and Ni-Cr(Fe).

These kinds of material can generate enough high temperatures to get the element glowed red hot, approximately 1112°F (600°C) and probably even higher.

Heaters that operate below this range are probably made from more various materials. Aluminum, copper, nickel, iron, molybdenum, and tungsten are also used.

How Hot Does A Dishwasher Need To Be To Sanitize?

During a regular wash cycle, the water temperature can reach between 140 and 145 degrees Fahrenheit.

A sanitize cycle must use an extended hot-water rinse and reach at least 150 degrees Fahrenheit to kill bacteria on your dishes and other utensils.

It is recommended to heat water up to 150°F at minimum. Some models are designed to even reach higher temperature.

Regularly, a sanitize cycle will increase the heat during the main wash and finish with a much hotter final rinse.

Do not misunderstand sanitize with sterilizing. Sterilizing function requires up to 180 degrees F.

How Hot Does A Dishwasher Get During Drying?

The last question relating to how hot do dishwashers get is how hot does a dishwasher get during dry cycle.

Not only taking charge of heating water temperature, heating element also heats dishes during the dry cycle. It can warm the inside of dishwasher to between 110 and 170 degrees Fahrenheit.

FAQs

Do dishwashers get hot enough to sterilize?

Yes, dishwashers are manufactured to be able to do the sterilizing.

They can get up to 180 degrees Fahrenheit to start the sterilizing cycle. Dishes will be well cleaned after being sterilized.

What is the highest temperature in a dishwasher?

Highest temperature is estimated to be around 170-180 degrees Fahrenheit in a dishwasher.

It is in sanitizing cycle or sterilizing cycle that a dishwasher temperature can reach this high temperature level.
