If your Whirlpool dishwasher isn’t heating water properly or is displaying error codes linked to the heating element, it might be time for a replacement. Fortunately, replacing the heating element is a straightforward process when you have the correct tools and safety precautions in place.
Signs the Heating Element Needs Replacement
Recognizing the symptoms of a faulty heating element can help you decide when to replace it. Here are common signs:
- Dishes Remain Cold or Wet: If your dishes are not dry or warm at the end of the cycle, the heating element may not be working.
- Error Codes: Whirlpool dishwashers often display error codes, like F7 or E1, which can indicate heating issues. Refer to the user manual for code meanings.
- Water Isn’t Heating: Run a hot water cycle. If the water remains lukewarm, the heating element might be failing.
Why Replacing the Heating Element Is Important
A functioning heating element plays a key role in your dishwasher’s performance. Here’s why replacing it matters:
- Proper Cleaning: Hot water improves the efficiency of detergents and removes tough food stains.
- Drying Dishes: Heat activates the drying cycle, leaving dishes clean and dry.
- Energy Efficiency: A faulty heating element can force the dishwasher to work harder, increasing energy consumption.
Replacing a faulty element can restore performance and prevent long-term damage to the appliance.
