Product review (4 stars): Part *works* but **doesn't** match the picture
We first ordered a door gasket to replace in our dishwasher where the picture showed a notch out of the middle of it. It was the right part number, but ours we took out was solid without a notch. When we tried it the door still leaked, but our spray arm also had a melted spot on it that was spraying right at the door and we weren't sure if the problem was the spray arm or because the notch was in the gasket. We ordered again getting this one, because the picture shown matched ours having no notch in the middle. When it arrived, it was the same part with the notch again. I read other's reviews again and tried the tips to replace the spray arm AND not to use the dishwasher for several hours after putting in the gasket so it could form a seal. My husband was skeptical about the notch and thought it would let water through again, but we tried it and installed the parts in the evening and let the dishwasher sit with the door kept closed overnight. We ran it the next day and no leaks! I think it's been a month now and all is working well still. So, if your spray arm is also needing replacement do that, and try letting the door sit closed overnight for the gasket to work properly.
