Fisher & Paykel Washer Error Code 105

Error code 105 indicates a communications time-out between the Display Module and the Motor Control Module. The Display Module initiated communication with the Motor Control Module but did not receive a valid response within the required time. The washer stops operation when this fault is detected. The primary diagnostic step is to replace the Display Module.

A power reset may temporarily clear the fault display, but if the underlying communication problem persists between the Display Module and Motor Control Module, the error will return. A reset is not a substitute for diagnosing and repairing the root cause. Continuing to cycle power without addressing the fault is unlikely to resolve the issue.

Repair costs depend on which component has failed. A Display Module replacement typically ranges from moderate to higher parts cost, and a Motor Control Module can be similarly priced or higher. Adding professional labor charges will increase the total. If only a wiring harness connection needs reseating or cleaning, the repair cost can be minimal.

Inspecting the wiring harness and connectors between the two control boards is something a technically confident DIYer can attempt. However, if the wiring is intact, resolving this error typically requires replacing the Display Module or Motor Control Module, which involves working with electrical components inside the machine. If you are not comfortable with appliance electronics, a qualified technician is recommended.

The washer will typically halt operation when this error is active, preventing normal use. You should not attempt to force the machine through a cycle while a communication fault is present. Leave the washer powered off until the fault has been diagnosed and repaired.
