Fisher & Paykel Washer Error Code 4

Error code 4 on a Fisher & Paykel washer is a Phase 1 communications fault. It means the Motor Control Module has had difficulty communicating with the Display Module. The machine stops operation and logs this code when the communication link between these two components breaks down. It can be caused by a transient electrical issue or an actual component failure.

The initial reset step is straightforward and safe for any homeowner to attempt. If the error persists, the repair involves accessing and replacing the Motor Control Module, which requires disassembling panels and working with electrical components. Technicians with appliance repair experience can handle this, but those unfamiliar with internal appliance components should contact a qualified service technician.

If a reset does not clear the fault, the repair will involve replacing the Motor Control Module. Parts and labor costs can vary depending on your region and service provider, but repair costs for control module replacements on front-load washers typically range from $150 to $400 or more depending on parts availability and labor rates. Getting a quote from a qualified Fisher & Paykel service technician will provide the most accurate estimate for your specific situation.

A reset is the first recommended step and may clear the fault if it was caused by a temporary electrical disturbance. Turn the machine off at the wall outlet, wait at least 5 seconds, then turn it back on and restart the cycle. If the code returns after the reset, the fault is persistent and likely requires replacing the Motor Control Module.

Error code 4 will typically prevent the machine from completing its cycle, so continued use is not generally possible while the fault is active. You should not attempt to bypass or ignore the fault, as the communication failure means the motor system cannot be properly monitored or controlled. Resolve the fault before resuming normal use.
