KitchenAid Dishwasher Error Code FAILED TEMP SENSOR OR ELEMENT

This error indicates a detected fault in the dishwasher's heating or temperature monitoring system. The possible causes include a failed heater element, a faulty temperature sensor, bad wiring or connections, or a problem with the electronic controller. The dishwasher displays this code when the control board cannot confirm that water is being heated correctly during a cycle. Diagnosing the specific failed component requires testing each part individually with the power disconnected.

Resetting the dishwasher by cutting power may temporarily clear the error, but it will return as soon as the unit attempts to heat water again if the underlying component has not been repaired. This code indicates an actual hardware or wiring fault, not a software glitch. A permanent fix requires diagnosing and replacing the failed component.

Repair costs vary depending on which component has failed. A replacement temperature sensor is typically the least expensive part, while a heater plate assembly or control board will cost more. Including labor, total repair costs generally range from around $100 to $400 or more depending on the specific part needed and local service rates. Getting a diagnosis first helps avoid replacing parts unnecessarily.

Start by unplugging the dishwasher or shutting off its circuit breaker, then use a multimeter to test the resistance of the heater element or heater plate. If the element shows an open circuit, replace the heater plate assembly. If the element tests correctly, move on to checking the temperature sensor and all associated wiring connectors for damage or corrosion. A control board replacement may be necessary if all other components test within spec.

Running the dishwasher with this error active means cycles are completing without confirmed proper water heating, which affects both cleaning performance and sanitization. If the heater element has a short rather than an open circuit, continued use could pose a safety risk. It is best to avoid using the appliance until the faulty component has been identified and replaced.
