GE Dishwasher Error Code F10

F10 on a GE dishwasher means the temperature sensor, or thermistor, is sending a reading that the control board interprets as abnormally high. The dishwasher stops the cycle as a protective response. In most cases, the sensor itself has failed rather than the water actually being too hot.

It is not recommended to continue running the dishwasher while F10 is active. The code causes the unit to stop the cycle, and attempting to bypass or ignore it could mask a real temperature issue. It is best to diagnose and repair the fault before resuming normal use.

If the thermistor is the cause, parts and labor typically range from around $75 to $175 depending on your location and the service provider. If the main control board needs replacement, costs can range from $150 to $350 or more, since the board itself is a more expensive component. Getting a diagnosis first helps avoid replacing parts unnecessarily.

A knowledgeable DIYer can start by inspecting the thermistor connector for corrosion or looseness, which sometimes resolves the issue without replacing any parts. If the connector looks good, testing the thermistor with a multimeter is the next step. Replacing the thermistor is a relatively straightforward repair, but if the control board is the cause, that replacement is more involved and may be better handled by a technician.

A reset may temporarily clear the F10 code, but it will almost certainly return once the dishwasher runs another cycle if the underlying problem is not fixed. The thermistor or control board fault that triggered the code will still be present. A reset alone is not a repair.
