GE Dishwasher Error Code F146

F146 on a GE dishwasher indicates a circulation pump error. The dishwasher's control board has detected a fault in the pump responsible for moving water through the spray arms during the wash cycle. The cycle stops to prevent further damage. Diagnosis starts with inspecting the pump wiring harness and, if needed, replacing the pump.

Resetting the dishwasher may temporarily clear the F146 code, but the error will return if the underlying problem with the circulation pump or its harness has not been resolved. A reset is useful for confirming whether a fault was intermittent, but it is not a fix. The root cause must be diagnosed and corrected to permanently clear the code.

Repair costs vary depending on the root cause. If the fix involves only reseating or repairing the wiring harness, costs may be minimal, primarily labor if a technician is involved. A replacement circulation pump typically costs between $80 and $200 for the part alone, with professional labor adding $100 to $200 on top of that depending on your location. Diagnosing the harness first before replacing the pump can help avoid unnecessary parts costs.

Some causes of F146 are DIY-friendly, particularly checking and reseating the wiring harness or clearing a jammed impeller. If the pump motor itself has failed, replacing it requires disconnecting water supply lines and electrical connections, which is manageable for a skilled DIYer with appliance repair experience. If you are not comfortable working around wiring and plumbing connections, a qualified technician is recommended.

It is not recommended to continue running the dishwasher while F146 is active. The error indicates the circulation pump is not operating correctly, meaning dishes will not be washed properly and the unit may sustain further damage if the fault involves an electrical issue such as a short or overloaded motor circuit. The dishwasher should remain out of service until the cause is identified and repaired.
