Understanding how to assess the condition of this vital part can save you from costly repairs and inconvenience. In this article, we’ll delve into how to determine if your Whirlpool dishwasher’s heating element is bad and what steps to take next.
Understanding the Heating Element’s Role
The heating element in your Whirlpool dishwasher is essential for several reasons. Primarily, it is responsible for:
- Heating Water: The heating element raises the temperature of the water to ensure effective cleaning and sanitizing of dishes.
- Drying Dishes: After the wash cycle, the heating element helps dry the dishes by heating the air inside the dishwasher.
When the heating element malfunctions, it can lead to several issues, including poor cleaning results and water remaining in the dishwasher post-cycle. Let’s explore how to identify potential problems with this critical component.
Common Symptoms of a Faulty Heating Element
Recognizing the signs of a failing heating element is essential for maintaining the efficiency of your Whirlpool dishwasher. Here are some key indicators:
No Hot Water During Cycles
One of the most evident signs that your heating element may be faulty is that the water inside your dishwasher isn’t reaching the necessary temperature during cycles. After running a hot wash cycle, check the water:
- If the dishes are still dirty.
- If the water feels lukewarm or cold.
If you notice either of these issues, it might be time to investigate the heating element.
Extended Drying Times
Another critical symptom to watch out for is extended drying times. If your dishwasher is taking much longer than usual to dry dishes, it may indicate that the heating element isn’t functioning correctly.
After the cycle completes, normally, the heat from the element would facilitate drying. However, if your plates, glasses, and utensils remain damp, it can be a sign of heating element failure.
Some Dishes Still Wet
Even with prolonged cycles, if you find that certain dishes are consistently wet or only mildly dry, it’s likely that the heating element is not producing sufficient heat.
In most modern dishwashers, the design ensures even heat distribution. If the heating element fails, this distribution is negatively affected, leading to inadequate drying results.
