My washer is about 12 years old and I found that the door hinge was bent down about a half inch. When being closed the little mating button with the button on the latch switch was busted off due to lifting to close the door. At my local appliance store the part is $105.00, I got a used one for $50.00. Besides replacing the part I partially opened the door and pulled up on the door until the hinge was straight and the buttons properly mated again. Thanks for the help, my budget wasn't including replacing a new set of washer and dryer and that is what I was being faced with.
