Fisher & Paykel Washer Error Code 231

Error code 231 on a Fisher & Paykel washer indicates a MW GW link error, meaning that a component on the display board has failed at Phase 6 of the machine's cycle. The communication link between the display module and the main controller has been lost. This is a hardware-level fault centered on the display assembly.

You should not continue operating the washer while error 231 is active. The failed display board component disrupts communication between the display and the main controller, which means the machine cannot reliably receive or confirm user commands. Running the washer in this condition could result in unpredictable behavior during a cycle.

A simple power reset is unlikely to permanently clear error code 231 because the fault is caused by a failed hardware component on the display board rather than a transient software glitch. The error may temporarily disappear after a reset but will return once the washer attempts communication at Phase 6 again. Replacing the display module is the correct resolution.

The recommended fix is to replace the display module. A knowledgeable DIYer comfortable with disassembling appliance control panels and working with PCB assemblies may be able to complete this repair. However, if you are not confident working with electronic components, it is advisable to have a qualified technician perform the replacement to avoid causing further damage.

Repair costs will vary depending on parts availability and whether you use a professional technician or complete the repair yourself. Display module parts typically range from $80 to $200 or more depending on the specific model. If hiring a technician, labor costs will add to this, generally bringing the total repair range to $150 to $350 or higher.
