Possible Causes

Misaligned door, Bent hinge, Defective door switch in lock, Broken door catch

How to Fix / Troubleshooting

Safety first: Unplug the washer before mechanical adjustments.

  • Check door alignment: Close the door slowly and observe if it lines up evenly with the cabinet. If it sags, the hinge may be loose.
  • Tighten hinge screws: Open the door and tighten the hinge screws on the front panel.
  • Inspect catch and lock: Look for wear or damage on the plastic door hook and the lock opening. Replace the hook if cracked.
  • If F34 continues: The door lock/switch assembly is likely faulty and should be replaced.
