GE Dishwasher Error Code F13

F13 on a GE dishwasher means the control board has received an inverter error. The inverter is the electronic component that controls the speed of the wash motor, and this code indicates it has reported a fault or has lost proper communication with the main control board. The dishwasher will stop operating until the issue is diagnosed and corrected.

A reset may temporarily clear the F13 code, but if the underlying fault in the inverter or harness is still present, the error will return once the dishwasher attempts to run the wash motor again. A reset is useful for confirming whether the fault is intermittent or persistent, but it does not fix the root cause.

If the fix is simply reseating a loose connector or cleaning a corroded terminal, the repair cost can be minimal or zero beyond your own time. If the inverter module needs replacement, parts alone typically range from around $80 to $200 or more depending on the model, with professional labor adding another $100 to $200 in most markets.

A knowledgeable DIYer can start by inspecting the wiring harness between the inverter and control board for loose connectors, corrosion, or visible damage, since a connection issue is often the cause. Reseating connectors requires no special tools and costs nothing. However, if the inverter module itself has failed, replacing it involves working near high-voltage components and may be better suited to a qualified technician.

No, you should not attempt to run the dishwasher while F13 is active. The code indicates a fault in the motor drive system, and the dishwasher has halted operation as a protective measure. Attempting to force a cycle with a faulty inverter could cause additional damage to the motor or control electronics.
