Hotpoint aquarius – model WM64N, stopped working. The door lock red light does not come on. Hence I initially believed the door interlock is faulty, it does not operate and lock the door and connect the live and the common to pass electricity to the rest of the washing machine. What confirm my suppression was when I connect the live on the door interlock mechanism to the common (by passing the internal mechanism) the washing machine works with no problem. Ordered a new door interlock and fitted it but still have the same problem. Can you help please
