KitchenAid Dishwasher Error Code Failed Temperature Sensor or Element LED

This LED indicates that the dishwasher's control board has detected a fault in the heating circuit. The issue could stem from a burned-out heater element, a failed temperature sensor, damaged wiring or connections, or a faulty electronic controller. The dishwasher may limit or suspend wash and dry cycle functions until the fault is resolved.

Running the dishwasher with this error active means water may not reach the temperatures needed for proper cleaning or sanitization, which is a hygiene concern rather than an immediate safety hazard. However, continued operation with a faulty heating circuit can place additional stress on the control board. It is best to diagnose and repair the fault before regular use.

A reset may temporarily clear the LED, but the error will return if the underlying fault has not been repaired. Resetting the appliance without fixing the heater element, temperature sensor, or wiring issue is not a permanent solution. Proper diagnosis and component repair or replacement are required to clear the fault reliably.

Start by unplugging the dishwasher and testing the resistance of the heater element with a multimeter. An open circuit reading means the heater plate needs to be replaced. If the element tests correctly, inspect all wiring and connectors in the heating circuit for corrosion or damage, then test the temperature sensor for correct resistance. If all components check out, the electronic controller may need to be replaced.

Repair costs vary depending on which component has failed. A replacement heater plate or temperature sensor typically ranges from $30 to $120 in parts, while a new electronic controller can range from $100 to $300 or more. Adding professional labor, total repair costs can range from $100 to $500 depending on the diagnosis and parts required.
