Fisher & Paykel Washers 42 Error: Motor controller fault
Fisher & Paykel washer error code 42 is a high-severity fault meaning Motor controller fault — brushless DC drive failure. A code 42 motor controller fault must be resolved before further use. A 5-minute power-cycle will clear the fault from memory.

Answer to continue safely
Is it safe to keep using?
No. A code 42 motor controller fault must be resolved before further use. Running the machine with a faulty motor controller risks escalating electrical damage to the stator windings, which are significantly more expensive to replace than the controller board alone.
Can I reset the code?
Yes. A 5-minute power-cycle will clear the fault from memory. If the code returns on the next spin cycle, the motor controller board or stator requires testing. Do not continue washing without identifying the root cause.
When to stop immediately?
Stop if you notice: Any burning smell or smoke comes from the machine base, Code returns immediately after power-cycle with a normal load.
Symptoms You May Notice
Code 42 flashes on display
The SmartDrive controller halts the cycle and flashes fault code 42, typically during the agitate or spin phase.
Basket stops mid-cycle
The wash basket stops rotating abruptly and will not restart even after the lid is closed and the start button is pressed.
Burning or electronic smell
A faint burnt-electronics odour may be detectable near the base of the machine where the motor controller board is mounted.
Possible Causes
Failed motor controller board
The motor controller PCB that drives the brushless DC stator windings has detected an over-current, over-temperature, or internal driver fault.
Requires ProfessionalShorted stator winding
One or more stator windings in the SmartDrive direct-drive motor have shorted, causing the controller to shut down to prevent further damage.
Requires ProfessionalLoose motor harness connector
The multi-pin connector between the stator and the motor controller has worked loose, triggering a drive fault.
DIY PossibleOverloaded basket
An excessively heavy load caused sustained over-current on the drive stage, tripping the controller's protection circuit.
DIY PossibleSafe Checks You Can Do
-
1
Remove excess load & power-cycle
Reduce the load to no more than the rated capacity, then unplug the machine for 5 minutes. Restore power and run a short rinse cycle to see if code 42 clears.
An overloaded SmartDrive is one of the most common triggers for a code 42 that resolves without parts replacement.

2
Inspect the motor harness connector
After unplugging, tilt the machine back and locate the motor controller at the base. Check that the multi-pin harness connector to the stator is fully seated and that no pins are bent or corroded.
Push the connector firmly until the locking tab clicks. Even a partially unseated connector can cause intermittent code 42 faults.
Tools required -
3
Check for visible motor board damage
With the machine unplugged, inspect the motor controller board for burnt components, cracked solder joints, or bulging capacitors.
Discolouration on the board near the IGBT driver area is a reliable sign of controller failure.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Motor controller board replacement requires access to 240V wiring and knowledge of SmartDrive PCB mounting
- Stator winding resistance tests require a multimeter and specific Fisher & Paykel resistance specifications
- Code persists after controller replacement, indicating possible rotor hall sensor damage
