Fisher & Paykel Washer Error Code 107

Error code 107 on a Fisher & Paykel washer indicates that the Display Module has detected an unexpected reset of the Motor Controller Module (MCM). Under normal operating conditions, the MCM should run continuously through a wash cycle without resetting. When the Display Module loses communication with the MCM or detects that it has rebooted mid-cycle, it logs this fault code to alert the technician that something has interrupted the controller's operation.

The two primary causes identified for this error are a supply disturbance and an internal microprocessor failure within the Motor Controller Module itself. A supply disturbance refers to an inconsistency or drop in the incoming power supply to the MCM, which can cause the controller's microprocessor to reset unexpectedly. This can stem from voltage fluctuations in the home's electrical supply, a failing power board, or degraded wiring connections feeding the module. In contrast, a microprocessor failure points to an internal hardware fault within the MCM where the processor itself is no longer stable and resets without any external trigger.

Because the MCM is responsible for managing motor speed, direction, and timing throughout the wash cycle, an unexpected reset will interrupt the cycle and trigger this fault. The Display Module continuously monitors the MCM's status, so even a brief unintended reset is captured and flagged. The recommended first diagnostic step is replacement of the Motor Controller Module, as this is the most direct resolution when an internal microprocessor failure or persistent instability is confirmed.
