I have an electra reversair deluxe tumble dryer 37468. The hinge plastic broke, so I bought a new hinge. I have successfully unscrewed the door from the machine and have prised the two parts of the door apart. I can see and touch the metal pin that holds the old broken hinge to the door, but I can’t seem to remove it. I don’t want to break it. How does the metal pin come out?
