Most common repairs needed to fix a Whirlpool dishwasher

Electronic Control Board Replacement

When your dishwasher is not heating, it could have a defective electronic control board. The control board sends current to the heating element when it’s working properly. A failed relay or corrupted logic on the circuit board could prevent the control board from sending electrical current to the heating element. Determining whether an electronic control board is defective is difficult. Have a Sears Home Services Repair Expert visit your home and fix the dishwasher when it is not heating.

Pump and Motor Assembly Replacement

When a dishwasher isn't heating, a faulty pump and motor assembly could be causing the failure. Heated water won’t move through the spray arms and heat dishes during the cycle when the pump and motor assembly is bad. A faulty pump and motor assembly leaves more water in the sump and prevents air from heating properly in the dishwasher. When your dishwasher isn’t heating and dishes aren’t getting clean, have a Sears Home Services Technician visit your home and fix the dishwasher.

User Interface Control Replacement

When your dishwasher is not heating, a damaged user interface control could be causing the problem. The user interface control connects to the electronic control board through a wire harness and sends signals to the control board to help control the dishwashing cycle. A bad heat selection key on the user interface control can prevent the dishwasher from heating because you won’t be able to select a heat setting for the cycle. Have a Sears Home Services Repair Expert visit your home and replace the user interface control if it’s damaged.

What to expect when you experience a Whirlpool dishwasher not heating issue

How is the not heating problem fixed?

Correcting most not heating problems usually involves replacing the electronic control board, pump and motor assembly or user interface control. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

Sears Home Services recommendations for a dishwasher that is not heating

When the dishwasher is not heating it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.

What to look out for with a dishwasher not heating diagnosis

Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

When your Whirlpool dishwasher fails to heat, lukewarm water can’t sanitize or dry dishes properly. A burnt-out heating element or temperature sensor often triggers this issue. Rather than dealing with soggy plates and partial cleaning, schedule a dishwasher repair near me. Once restored, your Whirlpool can return to delivering fully sanitized, dry dish loads.

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.
