Fault 57 is a low-voltage reading taken just before the display saved data; the Motor Controller module is the named part.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 57 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The 15 V supply measured below the safe level when the Display requested an EEPROM write.
The fault in one line
Fault 57 is the manual’s brown out warning for the Display’s memory writes, found on Phases 4, 5 and 6. EEPROM is a small memory chip that holds settings through a power-off, so 57 is really a warning about saving data.
Sequence inside the washer
The Display requests an EEPROM write from the Motor Controller module.
The Motor Controller measures its 15 volt supply first.
The reading is below the level considered safe for writing, and the Motor Controller tells the Display.
Why it might happen
The manual offers two explanations. One is a transient, a short electrical disturbance, striking while the write happens. The other is a faulty Motor Controller module. That module is the primary source, and swapping it is the single action listed. The entry holds no owner check.
Practical points
Make a note of whether 57 showed up once or keeps coming back. The console should stay shut while the washer is plugged in.
Related memory and supply codes
61 repeats this 15 V test, but when the controller saves to its own memory (Phase 4).
60 is a controller memory check that failed at power-up.
A Fisher & Paykel washer in Los Angeles that keeps returning 57 can be reported on (310) 872-1939, and the washer repair page gives the general overview. Have the model number to hand and say how often the code appears.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
