Kitchenaid Dishwasher Error Code 7-2 or F7E2

When your KitchenAid dishwasher displays the Error Code 7-2 or F7E2, it signals a specific issue related to the heating element. In this scenario, the heating element is not shutting off as it should, potentially leading to overheating and operational problems.

1. Electronic Control Board Malfunction: The electronic control board, responsible for regulating various dishwasher functions, may fail to signal the heating element to turn off.
2. Heating Element Issues: The heating element itself might be defective, causing it to remain active even when the dishwasher cycle is complete.

Troubleshooting Steps:

1. Power Cycle the Dishwasher:

   • Turn off the dishwasher and disconnect it from the power source.
   • Allow the dishwasher to remain unplugged for at least 5 minutes to reset the system.
   • Reconnect the power and turn on the dishwasher.

2. Observe Code Resumption:

   • Monitor the dishwasher to see if the Error Code 7-2 or F7E2 reappears after the power cycle.
   • If the code persists, it indicates a potential electronic control board issue.

3. Inspect Heating Element:

   • Carefully examine the heating element for visible damage or signs of wear.
   • Check for loose connections or burnt areas on the heating element.

4. Replace Electronic Control Board:

   • If the code recurs and the heating element appears to be in good condition, it’s advisable to replace the electronic control board.
   • Contact a professional technician, like those at KitchenAid Appliance Support, for an accurate diagnosis and replacement of the electronic control board.

Dealing with electronic components and dishwasher internals requires precision and expertise. If the Error Code 7-2 or F7E2 persists after basic troubleshooting, seeking professional help ensures a thorough examination and proper replacement of faulty parts.
