Fisher & Paykel Washer Error Code 27

Error code 27 means the Motor Control Module has detected an abnormal voltage reading from the valve diagnostic circuit. This indicates a fault with the cold water valve, both the cold and hot water valves, or the dispensing valves. The fault can be caused by loose wiring connections, bent connector pins, or a failed valve solenoid. The washer will not operate normally until the fault is resolved.

A power reset may temporarily clear the code, but if the underlying valve or wiring fault is still present, the error will return once the machine attempts to operate the affected valve. The fault needs to be diagnosed and repaired rather than simply reset. Repeatedly resetting without fixing the cause will not restore normal operation.

If the fault is only a loose or damaged connector, repair costs may be minimal, covering only labor time for diagnosis. If a water inlet valve solenoid needs to be replaced, parts costs typically range from around $30 to $100 or more depending on the specific valve, with additional labor charges if a technician performs the repair. Diagnosing the exact failed component first is important to avoid replacing parts unnecessarily.

Start by checking all harness connectors at the inlet valves and at the Motor Control Module, making sure each connector is fully seated and that no pins are bent or pushed backward. If connections look good, test the solenoid coils on the cold, hot, and dispensing valves for continuity and proper resistance. Also inspect the wiring harness for any visible chafing or damage along its routing path. If a valve solenoid has failed, it will need to be replaced.

It is not recommended to continue using the washer while error code 27 is active. A faulty valve circuit can result in incorrect water fill behavior, and the MCM has halted normal operation to prevent potential issues. Running the machine while the fault is unresolved could place additional stress on related components.
