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 there's an issue with the board's logic, it can stop the heat. Figuring out if the control board is the problem can be tricky. To get it sorted, have a Sears Home Services Repair Expert check and repair your dishwasher when it's not heating up.
Water Valve Replacement
If your dishwasher isn't heating up, a blocked fill valve might be the culprit. When there's insufficient water entering the dishwasher, a safety thermostat kicks in and cuts power to the heating element to prevent overheating. This safety feature won't reset until the tub cools down and refills with water. To resolve this issue, schedule a visit from a Sears Home Services Technician to address both the heating and filling problems with your dishwasher.
Detergent Dispenser Replacement
If your dishwasher isn't heating up, a faulty detergent dispenser might be to blame. A damaged water seal around the base of the dispenser can permit water to infiltrate the inner door panel, potentially damaging wiring or internal components. This damage could prevent the electronic control board from supplying power to the dishwasher's heating element. To address this issue, arrange for a Sears Home Services Expert to inspect your appliance and replace the defective detergent dispenser.

Sears Home Services expert tips for a dishwasher that won't heat
If your dishwasher isn't heating up, it could be due to several reasons. To avoid changing parts unnecessarily, we suggest having a Sears Home Services expert run diagnostic tests to find the main issue. Our technicians are skilled at diagnosing all kinds of dishwasher problems.
What to watch for with a dishwasher no heat diagnosis
Figuring out what's wrong with modern appliances without the right knowledge and training can be tough. If you don't use the right diagnostic methods, you might end up just guessing and changing parts unnecessarily. Appliances, especially newer ones, have gotten really advanced in the last decade. They often have electronic parts that are hard to check. Fixing them yourself is getting harder, too.

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.
