Fisher & Paykel Washer Error Code #51

Error code #51 indicates a diverter valve fault where wash water is not circulating correctly through the recirculation hose. The diverter valve controls the direction of water flow during the wash cycle, and the machine has detected that circulation is not happening as expected. The washer stops the cycle when this code appears to prevent poor wash results or potential damage.

It is not recommended to continue running the washer while this error is active. The machine has detected that the recirculation system is not functioning correctly, which means clothes may not be washed properly and an underlying fault could worsen with continued use. Address the cause before running another cycle.

A reset may temporarily clear the code and allow the machine to restart, but if the underlying fault is still present, the error will return during the next wash cycle. A reset should only be used after you have identified and corrected the cause of the fault, such as removing a blockage or repairing a wiring connection, to confirm the repair was successful.

Some causes of #51 are DIY-friendly, such as clearing a blockage from the recirculation hose or checking that all hose connections are tight and leak-free. Checking wiring connectors at the diverter valve is also within reach for a careful DIYer. However, testing coil resistance requires a multimeter, and replacing the Motor Control Module is a more involved repair that many homeowners prefer to leave to a technician.

Repair costs depend on the root cause. Clearing a hose blockage yourself costs nothing beyond your time, while a replacement diverter valve typically runs in the range of $40 to $120 for the part. If the Motor Control Module needs replacement, parts and labor combined can range from $200 to $500 or more depending on your location and the specific model.
