My repair person told me I would have to buy a new washer because new door gaskets are hard to replace and they seldom fix the problem. The old gasket looked fine but decided to try a new one first, instead of buying a new washer. I pulled the old gasket out, no glue to worry about, then pushed the new one into place. Very simple repair. The door is now more difficult to latch closed because it has a much tighter fit. I compared the old gasket to the new one and then I noticed how the old one had shrunk and was worn. Now, no more leaks!
