hi there have done this before. All you have to do is open the door and put your fingers on the inside of the rubber, and you should feel a mettal plate hold that with finger while undoing the 2 screws. You will now find that the door comes off in your hand. Put the new hinge over the holes (still holding the other plate behind the rubber) and put the screws back in the holes. Screw tight. (you can buy a new hinge for £10 from your local cooker/ washing machine shop). Take the door off the old hinge and then screw on to new one. hope this helps.
