Washing machine starts but door opens during cycle

The problem

The machine had previously failed to start with the door lock light flashing. After the door interlock was replaced, it worked for a couple of weeks. It then began recognising the door as locked and starting, but the door could swing open.

Likely cause

The accepted reply says this is unlikely to be an electrical locking fault alone. The most strongly supported cause is that the door is not closing and latching correctly, or the replacement door lock/interlock is not fitted correctly. A weak or faulty door latch spring was specifically suggested.

What fixed it

Check the door latch and confirm it has a spring holding it in position. Also check that the door lock/interlock is fitted correctly. The accepted suggestion was to spray the latch and door lock with WD40. The exact repair that solved it was not confirmed in the thread.

Checks to try

• Checked/replaced the door interlock twice
• Check the latch on the door
• Check whether the latch spring is present and holding the latch in position
• Check whether the door lock is fitted correctly

Parts or tools mentioned
