This dishwasher leaks out the door. It seems there should be a gasket there. Unclear why it isn't there, but based on manuals and videos I can find, this model always has one, and it's typical of all dishwashers.

GE has the part listed, and I ordered the correct part number from a cheap third party site. But I can't get it to stay in there long enough to even test shutting the door.

Should I use some kind of high temp adhesive? What if it doesn't actually fit, like it doesn't let the door properly shut? Will it be difficult to remove the adhesive and try again? I hate dishwashers, but this is for someone else.

Thanks for any input

I haven't gleaned any extra clues there but I'm at a loss. Stupid thing is listed for $430 u.s.
