GE Dishwasher Error Code F3

The F3 code on a GE dishwasher is a configuration error indicating that the control board cannot detect the inverter module, which is required on inverter-equipped models. The board checks for the inverter during startup, and if it does not receive the expected response, the F3 code appears and the dishwasher stops normal operation. This is typically caused by a loose connection, wiring issue, or a failed inverter module.

A reset may temporarily clear the F3 code, but it will return as soon as the control board runs its configuration check again at startup if the underlying issue has not been resolved. The code will keep reappearing until the inverter is confirmed present, properly connected, and functioning correctly.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost involved, though a service call fee typically ranges from $75 to $150. If the inverter module needs replacement, parts and labor combined can range from $150 to $350 or more depending on the specific model and local labor rates.

Start by checking that the inverter module is present and that its wiring harness connectors are fully seated at both the inverter and control board ends. Inspect the connector pins for corrosion or damage and reseat any loose connections. If the connections are solid and the error persists, the inverter module or the control board may need to be replaced by a qualified technician.

No, the dishwasher is not designed to run normally while the F3 code is active. Because the code indicates the motor control inverter is not detected, the wash motor cannot be properly controlled. Attempting to force the machine through a cycle in this state is not recommended and could cause further damage.
