Product review (5 stars): When I put in the new spray arm all leaks were gone and it's working like new again (cleaning the dishes better as well)
Our dishwasher started leaking in the corner. I removed the existing gasket, which was probably 7 years old and it was filthy and falling apart. I cleaned everything up and put this new gasket in. The leak in the bottom corner of the door was solved, but I had a new leak in the middle of the door. Confident that I had the right gasket and had it correctly installed, I closely examined my dishwasher and found that my lower spray arm was melted and spraying directly at the door! When I put in the new spray arm all leaks were gone and it's working like new again (cleaning the dishes better as well). I also checked for levelness because that can cause front door leaks.
