Whirlpool dishwashers have long been known for their reliability and efficiency in cleaning dishes. However, like any other appliance, they can encounter issues from time to time. One common problem that many owners face is their Whirlpool dishwasher is not heating properly. When this happens, it can lead to dishes coming out dirty or still wet, defeating the purpose of using a dishwasher in the first place. In this article, we’ll discuss the importance of proper heating in dishwashers and provide troubleshooting tips for fixing heating issues in Whirlpool dishwashers.

Introduction to Whirlpool Dishwashers

Whirlpool is a reputable brand known for producing high-quality home appliances, including dishwashers. Whirlpool dishwashers are designed to make dishwashing convenient and efficient, saving users time and effort. These dishwashers typically come equipped with various features, including multiple wash cycles, adjustable racks, and energy-saving options.

Importance of Proper Heating in Dishwashers

Proper heating is crucial in dishwashers as it helps in sanitizing dishes and drying them effectively. When a dishwasher fails to heat the water to the appropriate temperature or if the heating element malfunctions, it can result in inadequate cleaning and drying of dishes. This not only compromises the cleanliness of the dishes but also increases the risk of bacterial growth.

Common Issues with Whirlpool Dishwasher Heating

There are several common issues that can cause a Whirlpool dishwasher to stop heating properly:

Lack of Hot Water

  • If the dishwasher is not filling up with hot water, it won’t be able to clean the dishes effectively. This can happen due to problems with the water inlet valve or issues with the household water heater.

Faulty Heating Element

  • The heating element in a dishwasher is responsible for heating the water and drying the dishes. If the heating element is defective or damaged, the dishwasher may fail to heat the water to the desired temperature or dry the dishes properly.

Defective Thermostat

  • The thermostat regulates the temperature inside the dishwasher. If the thermostat is faulty, it may not signal the heating element to turn on, resulting in the dishwasher not heating properly.

Clogged Spray Arms

  • Clogged spray arms can obstruct the flow of water inside the dishwasher, preventing it from reaching the necessary temperature for effective cleaning and sanitization.

Troubleshooting Steps for Whirlpool Dishwasher Not Heating

If you’re experiencing heating issues with your Whirlpool dishwasher, here are some troubleshooting steps you can try:

Check Water Temperature

  • Ensure that the water entering the dishwasher is hot enough. Run the kitchen sink faucet until the water is hot, then start the dishwasher. If the water is not hot, it could indicate a problem with the household water heater.

Inspect Heating Element

  • Inspect the heating element for any visible signs of damage or corrosion. If the heating element appears damaged, it may need to be replaced.

Test Thermostat

  • Test the thermostat using a multimeter to determine if it’s functioning properly. If the thermostat is defective, it will need to be replaced.

Clean Spray Arms

  • Remove the spray arms from the dishwasher and clean them thoroughly to remove any debris or buildup. Clogged spray arms can impede water flow and affect the dishwasher’s ability to heat properly.

DIY Solutions for Heating Problems

If you’ve identified the cause of the heating issue in your Whirlpool dishwasher, here are some DIY solutions you can try:

Adjusting Water Temperature

  • Increase the temperature setting on your household water heater to ensure that the dishwasher receives hot water.

Replacing Heating Element

  • If the heating element is damaged or faulty, you can replace it with a new one following the manufacturer’s instructions.

Resetting Thermostat

  • Some dishwashers have a reset button for the thermostat. Try resetting the thermostat to see if it resolves the heating issue.

Cleaning Spray Arms

  • Regularly clean the spray arms to prevent debris from accumulating and obstructing water flow.

When to Seek Professional Help

If you’ve tried troubleshooting the heating issue in your Whirlpool dishwasher and haven’t been able to resolve it, it may be time to seek professional help. A certified appliance repair technician can diagnose the problem accurately and recommend the necessary repairs or replacements.

What makes a Whirlpool dryer so reliable? Several factors contribute to this reputation. First, all Whirlpool dryers are built with quality components. They feature advanced technologies like moisture sensors and wrinkle prevention systems, which help keep your clothes looking and feeling great. Second, Whirlpool is committed to customer satisfaction. A comprehensive warranty backs its products, and Whirlpool’s team of dedicated customer service representatives is always available to help you with any problems or questions you may have.


A Whirlpool dishwasher not heating properly can be frustrating, but with the right troubleshooting steps, you can identify and resolve the issue effectively. By ensuring that the dishwasher receives hot water, inspecting and cleaning components like the heating element and spray arms, and seeking professional help when needed, you can keep your dishwasher running smoothly and efficiently.
