Fisher & Paykel Washer Error Code #50

Error code #50 on a Fisher & Paykel washer signals a fault in the hot and/or cold water inlet valve circuit. The control board has detected an open circuit or wiring problem with one or both solenoid valves that control water flow into the machine. The washer will stop operation until the issue is identified and corrected.

It is not advisable to continue operating the washer while error code #50 is active. The fault indicates a problem with water valve control, which could result in improper filling or no water entering the drum at all. Running a cycle under these conditions risks damage to the motor, drum components, or laundry load.

A power reset may temporarily clear the error code from the display, but it will return as soon as the control board attempts to operate the faulty valve circuit again. The underlying electrical fault, whether a loose connection or a failed solenoid coil, must be diagnosed and corrected for the code to be permanently resolved.

The first step is to check that the wiring harnesses to both the hot and cold water inlet valves are properly connected, which is a straightforward inspection that does not require specialized tools. If the connections are secure, testing the valve solenoids with a multimeter for continuity is the next step. Replacing a faulty inlet valve is a moderately involved repair that many experienced DIYers can complete, though comfort with appliance disassembly and basic electrical testing is recommended.

If the issue is only a loose or disconnected harness, there is no parts cost involved. If a water inlet valve solenoid has failed and needs replacement, parts typically range from $30 to $90 depending on the specific valve and whether it is a hot, cold, or combination unit. Adding professional labor, total repair costs generally fall in the range of $100 to $250.
