GE Dishwasher Error Code F215

The F215 error code on a GE dishwasher indicates that the machine control board has detected a fault in the AC power connections or the AC load circuit. The control board continuously monitors the integrity of AC harness connections and the electrical loads connected through them, including components such as the wash motor, drain pump, heating element, and dispenser. When the board detects an irregularity in this circuit, whether from a loose connection, a short, or an unexpected load reading, it triggers the F215 fault to prevent potential damage to the control electronics or connected components.

The most common root causes involve physical harness issues rather than outright component failures. Vibration during wash cycles can loosen wire connectors at the control board or at individual load components over time. Moisture intrusion, which is common in dishwasher environments, can cause corrosion at connector pins, increasing resistance and disrupting the expected electrical signal. A failed or shorted load component, such as a seized pump motor or a failed heating element, can also produce an abnormal current draw that the board interprets as a fault condition.

Diagnosis requires a systematic inspection of all AC wiring harnesses, starting at the machine control board and tracing through to each connected load. Connectors should be checked for secure seating, corrosion, and signs of heat damage. If all harness connections are confirmed solid and loads appear intact, the machine control board itself is likely misreading the circuit and should be replaced.
