It's on file for the GW512 and GW612 and for the WA55T56MW1 and WA65T60MW1 as well. Use the model and serial number from the label on your machine to confirm fit before ordering.

When a Fisher & Paykel washer PCB module is the problem

This module takes commands from the console, then drives the motor, opens the water valves and runs the drain pump while keeping track of the lid and water level. When it starts to fail, a washer might not power up, could stop mid-cycle, may spin erratically or flash the same fault code again and again. Burnt tracks or a smell of hot electronics around the module are clear warning signs. A faulty motor, pump or sensor can trigger similar symptoms, so test those parts before replacing the board.

Fitting the new PCB module

Pull the power plug and shut off the hot and cold taps first. We recommend a qualified appliance technician for this job. Label or photograph each plug as it comes off the old module, as several look alike. Transfer the connections one at a time, secure the module in its housing and keep all wiring clear of moving parts. Finish with a complete wash and spin to check every function.
