The unit will only run if the door is held shut. As soon as I stop pushing, the unit stops running. I tried adjusting (forward and back) the metal catch on top of the unit but this did not help. It has been a good dishwasher, although the racks are starting to rust. It usually runs only 3 or 4 times a week. Trying to determine the problem, cost of the replacement part(s), and difficulty of replacement.
Thanks, Mike.
