GE Dishwasher Error Code F17

F17 on a GE dishwasher means the control board is detecting an absent heat source. The dishwasher is not registering the expected heating activity during the wash or dry cycle. The error points to the heater element, thermistor, or the wiring connecting them to the control board as the likely source of the problem.

Running the dishwasher with F17 active is not recommended. Without a functioning heat source, the appliance will not sanitize dishes properly and the drying cycle will not perform as intended. Continuing to run cycles while the fault is unresolved can also put additional strain on other components.

A reset may temporarily clear the F17 code, but it will return if the underlying problem is not repaired. The control board triggers F17 because it cannot detect heat, and that condition will persist until the faulty component is replaced or the wiring issue is corrected. Resetting without repairing should only be done as part of the diagnostic process, not as a long-term solution.

A knowledgeable DIYer can diagnose and fix F17 in many cases. Start by checking the heater element for continuity and the thermistor for correct resistance using a multimeter. If either component tests as failed, replacing it is a straightforward repair. Wiring issues can also be resolved without professional help if the damaged section is accessible.

Repair costs depend on which component has failed. A replacement heater element typically runs between $20 and $60 for the part, while a thermistor is usually in the $10 to $40 range. If you hire a technician, labor costs can add $80 to $150 or more on top of parts. A control board replacement, if needed, is the most expensive scenario and can push total costs significantly higher.
