Kenmore Dishwasher Error Code F3E2

F3E2 indicates a shorted connection or component in the temperature sensing circuit. This can be caused by incoming water that is too hot (above 167°F / 75°C), a shorted or failed thermistor, or damaged wiring and connectors in the sensing circuit. The dishwasher stops normal operation when this code appears to prevent potential damage from uncontrolled temperatures.

It is not recommended to continue running the dishwasher while F3E2 is active. The code signals a fault in the temperature sensing circuit, meaning the control may not be accurately monitoring water temperature. Operating the unit in this condition could result in improper washing performance or, if water is genuinely overheating, potential damage to internal components.

Repair costs vary depending on the root cause. If the fix is simply lowering the water heater temperature, there is no parts cost. Replacing a thermistor typically runs in the range of $15 to $50 for the part, with labor adding $75 to $150 if a technician is needed. A control board replacement is the most expensive scenario, often ranging from $150 to $350 or more for parts and labor combined.

Some causes of F3E2 are DIY-friendly. If your water heater is set too high, lowering it below 167°F can clear the code without any parts. Inspecting wiring and connectors for visible damage is also within reach for a careful DIYer. Replacing the thermistor is a moderate repair, but always unplug the dishwasher before working on any electrical components.

A reset may temporarily clear the F3E2 code, but it will return if the underlying fault is not corrected. If the root cause is a shorted thermistor, damaged wiring, or persistently high incoming water temperature, the code will reappear once the next cycle begins. Diagnose and repair the cause before relying on a reset.
