GE Dishwasher Error Code Over Temperature

The Over Temperature error means the dishwasher's control detected water temperature above 180°F but below 210°F during a cycle. This falls outside the safe operating range and causes the machine to stop. The most likely culprits are the door thermistor and the overtemperature thermostat, which are the first components to inspect.

You should not continue running the dishwasher until the cause is identified. Water heated above 180°F can damage internal components including hoses, seals, and plastic parts. If the heating element is running unchecked, continuing to operate the machine could worsen the damage or create a safety hazard.

Resetting the dishwasher may clear the error code temporarily, but if the underlying component fault remains, the error will return once the machine runs a heated cycle again. A reset is useful for confirming whether the issue is persistent, but it is not a fix. Proper diagnosis of the thermistor and thermostat is needed to resolve the error permanently.

A knowledgeable DIYer can check the door thermistor and overtemperature thermostat with a multimeter to determine whether either component has failed. Replacing a thermistor or thermostat is a moderately straightforward repair if you are comfortable working with appliance wiring. However, if the heating element or control board is involved, professional diagnosis may be the safer route.

Repair costs depend on which component has failed. A replacement door thermistor or overtemperature thermostat typically costs between $15 and $60 for the part alone. If a technician performs the diagnosis and repair, total costs including labor generally range from $100 to $250. A failed control board represents the most expensive scenario, with parts and labor potentially reaching $200 to $400.
