What Does Error E4 Mean?
The Fisher & Paykel washing machine E4 error code signals a drainage issue, often due to a severely unbalanced load or problems with the rotor position sensor. This error prevents the machine from starting or completing its cycle, leading to potential overfill. Users may notice vibration or imbalance during operation, particularly on combo models where water level detection may fail. To resolve this, check for an even distribution of laundry and ensure the machine is properly leveled.
Common Symptoms:
- Washer displays E4 and will not start or stops shortly after starting
- Machine stops during spin or fails to progress cycle
- Possible vibration or imbalance
- On some combo models, water level misreading/overfill behaviour
Possible Causes
- Severely unbalanced load (medium)
- Faulty rotor position sensor or SmartDrive rotor assembly issue (medium)
- Suspension/shock absorber failure leading to imbalance (medium)
- Water level sensor/pressure switch fault (low)
