How to Fix / Troubleshooting

Safety first: Switch off and unplug the appliance. Ensure the drum is not full of hot water before forcing the door.

Step-by-step checks:

  • 1. Wait a few minutes: Many models have a delay before unlocking. Allow 2–5 minutes after cycle end.
  • 2. Drain water: If water is visible, use the emergency drain hose or pump filter to empty the tub.
  • 3. Use emergency release: Access the manual door release behind the pump flap (if fitted) and pull gently.
  • 4. Inspect and replace lock: Once open and unplugged, access the lock and replace it if mechanically jammed.

When to call a technician: If the door cannot be opened without risk of damage, professional assistance is advised.
