How Hot Does a Dishwasher Get? Exploring Water Temperature and Drying Process

How Hot Does a Dishwasher Get?

When it comes to cleaning our dishes, dishwashers have become an essential appliance in many households. They save us time and effort, but have you ever wondered how hot a dishwasher gets? In this article, we will explore the temperature range of dishwashers, how they heat the water, and provide troubleshooting examples and solutions for common issues users may experience.

How Hot Does a Dishwasher Get When Washing?

A dishwasher typically heats the water to a temperature between 120°F (49°C) and 160°F (71°C) during the washing cycle. This high temperature is necessary to effectively remove food particles, grease, and bacteria from your dishes. The exact temperature may vary depending on the dishwasher model and settings.

At such high temperatures, dishwashers are able to break down and dissolve stubborn stains and grease that may be difficult to remove by handwashing. The hot water also helps to sanitize your dishes, ensuring they are safe for use.

How Hot Does a Dishwasher Get When Drying?

During the drying cycle, dishwashers use a combination of heat and air circulation to remove moisture from your dishes. The temperature inside the dishwasher can reach up to 140°F (60°C) during this phase. This high temperature helps to evaporate the water on your dishes, leaving them dry and ready to be put away.

It’s important to note that some dishwashers also offer a “heat dry” option, which increases the drying temperature even further. This option can be particularly useful for plastic items that tend to retain moisture.

Do Dishwashers Heat the Water?

Yes, dishwashers have built-in heating elements that heat the water to the desired temperature. The heating element is typically located at the bottom of the dishwasher, and it works by converting electrical energy into heat. This heat is then transferred to the water, raising its temperature to the appropriate level for effective cleaning.

It’s worth mentioning that some dishwashers also have a feature called “water heating delay” or “sanitizing rinse,” which increases the water temperature even further to kill bacteria and ensure thorough cleaning.

Do Dishwashers Use Hot or Cold Water?

Dishwashers primarily use hot water to clean your dishes. The hot water helps to dissolve detergent, remove stains, and sanitize your dishes. However, dishwashers do not heat the water themselves; they rely on the hot water supply from your home’s water heater.

It’s important to ensure that your water heater is set to an appropriate temperature to provide hot water for your dishwasher. The recommended temperature for hot water in a dishwasher is 120°F (49°C). This temperature is hot enough to clean and sanitize your dishes effectively while also being energy-efficient.

Troubleshooting Examples and Solutions

While dishwashers are generally reliable appliances, they can sometimes encounter issues that affect their performance. Here are a few common problems users may experience and their possible solutions:

  • Dishes not getting clean: If your dishes are not getting clean, it could be due to a clogged spray arm or a malfunctioning water pump. Check the spray arm for any blockages and clean it if necessary. If the water pump is not working properly, it may need to be replaced.
  • Dishes not drying: If your dishes are not drying properly, make sure the dishwasher’s heating element is functioning correctly. If the heating element is faulty, it may need to be replaced. Additionally, ensure that you are using a rinse aid, as this can improve drying performance.
  • Strange odor: If your dishwasher has a foul odor, it could be due to food particles trapped in the filter or spray arm. Clean the filter and spray arm regularly to prevent odor buildup. You can also run a cycle with a dishwasher cleaner to eliminate any lingering smells.

Replacement Parts for Dishwashers

If you need to replace any parts in your dishwasher, it’s important to use genuine spare parts to ensure compatibility and optimal performance. Common replacement parts for dishwashers include:

  • Heating element
  • Spray arm
  • Water pump
  • Filter
  • Rinse aid dispenser

When replacing parts, it’s recommended to consult the dishwasher’s user manual or seek professional assistance if you’re unsure about the process. Calling the authorized service for your dishwasher brand is often the best course of action to ensure proper installation and avoid any potential damage.


Dishwashers play a crucial role in our daily lives, providing convenience and efficiency in cleaning our dishes. Understanding how hot a dishwasher gets and how it heats the water can help us make the most of this appliance. By following proper maintenance and troubleshooting steps, we can ensure that our dishwasher continues to perform optimally. Remember, if you encounter any issues or need replacement parts, it’s best to consult the manufacturer’s official website or call their authorized service for the most accurate and up-to-date information.
