The door to the machine does not seem to lock into place when closing the door. The machine starts even when the door is open. The handle to the door is fine just seems to be the lock. Not sure if it is a new locking mechanism that is required.
your interlock might of gone.as well as this,your door might need adjusting.when you shut the door,try lifting it then shutting it.We have the same problem,only ours wont start if the door is open
hope it helps!!
