Two problems with replacing hinge.How do I hold the plate that the 2 hinge screws screw into. This will be free to drop into the machine when I remove the 2 hinges. Is it simple to remove the door seal to gain access to the plate?. How do I seperate the two parts of the door to enable removing the old bits of broken hinge. I have taken out the 4 screws but it still will not seperate.?
