Common dishwasher repair parts you may need
Replacing one of these dishwasher parts may fix your problem.
Electronic Control Board Replacement
If your dishwasher isn't heating up, it might be due to a faulty electronic control board. This board is responsible for sending power to the heating element. If a relay fails or if the board's logic is damaged, it can stop sending power to the heating element. Diagnosing a defective control board can be tricky. It's best to have a Sears Home Services Repair Expert inspect and repair the dishwasher if it's not heating properly.
Pump and Motor Assembly Replacement
If your dishwasher isn't heating up, it might be due to a faulty pump and motor assembly. When this assembly is not working properly, heated water cannot flow through the spray arms to heat up the dishes during the cycle. As a result, more water remains in the sump, preventing proper heating in the dishwasher. If you notice that your dishes aren't getting clean and the dishwasher isn't heating, it's best to have a Sears Home Services Technician inspect and repair the dishwasher.
User Interface Control Replacement
If your dishwasher isn't heating, a damaged user interface control might be the culprit. This control is connected to the electronic control board via a wire harness and sends signals to regulate the dishwashing cycle. If the heat selection key on the user interface control is faulty, it can prevent the dishwasher from heating because you won't be able to choose a heat setting for the cycle. To address this issue, it's advisable to have a Sears Home Services Repair Expert come to your home and replace the damaged user interface control.

What to look out for when facing a dishwasher not heating diagnosis
Diagnosing modern appliances without the right knowledge and training can be tough. If you don't use proper diagnostic techniques, trying to fix your dishwasher might mean randomly replacing parts. Appliances, especially those made in the last decade, have gotten very advanced, with electronic parts that are hard to check. Fixing the latest appliance models on your own is getting harder.

Thorough
James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
