KitchenAid dishwasher not heating

Why is my KitchenAid dishwasher not getting hot?

A defective electronic control board, faulty high-limit thermostat, bad heating element or wiring failure are the common causes of a heating problem in a KitchenAid dishwasher.

Check the High-Limit Thermostat

The high-limit thermostat at the bottom of the dishwasher tub shuts off the heating element when it detects water temperature above 207 degrees Fahrenheit.

A defective high-limit thermostat trips at a cooler temperature, preventing the heating element from heating. With the electrical power disconnected from your dishwasher, you can check for electrical continuity through the high-limit thermostat using a multimeter.

If you measure no continuity at room temperature, the high-limit thermostat tripped and is defective.

Use the procedure in this video to access the high-limit thermostat and replace that component if you measure no continuity through the thermostat spades.

Test the Heating Element

The heating element at the bottom of the dishwasher tub heats water during the wash and rinse cycles and air during the heated drying cycle.

Check the heating element and replace it if you see physical damage such as a cracked or broken element.

If you see no physical damage, you can test the element using a multimeter.

Access the heating element as shown in this safe DIY video:

Measure resistance through the element using a multimeter. You should measure between 10 and 40 ohms through the element.

If you measure no continuity through the element, replace it as shown in the above video.

If these tips don’t help you fix the problem with your KitchenAid dishwasher not heating, then a bad electronic control board or wiring failure could be causing the problem. You’ll likely need to have a service technician check the dishwasher for these failures.
