Fisher & Paykel Washer Error Code 137

Error code 137 on a Fisher & Paykel washer indicates a motor phase loss condition. The drive motor in these machines is a three-phase motor, meaning it requires three separate electrical phases to operate correctly. When one of those phases is interrupted or absent, the Motor Control Module detects the imbalance and throws this fault code to prevent the motor from running in a degraded state that could cause further damage.

The three most common sources of this fault are a damaged wiring harness, an open circuit in one of the motor windings, or a failed Motor Control Module. The harness routing from the controller to the motor is subject to vibration and movement during spin cycles, which over time can cause wire fatigue, broken conductors, or connector corrosion. An open winding inside the motor itself means the motor must be replaced. A faulty controller is considered when the harness and motor check out correctly.

Diagnosis begins at the Motor Control Module end of the harness. Each motor phase winding should measure approximately 39 ohms of resistance. A reading of infinite resistance (open circuit) on any phase confirms either a broken wire in the harness, a failed connector, or an open motor winding. Readings significantly outside the 39 ohm nominal value can also indicate a degraded winding. Always check connector pins for corrosion, bent terminals, or loose seating before condemning the motor or controller.
