Product review (5 stars): GE Dishwasher door leak stopped.
I have an older GE dishwasher that started to leak at door edge. I researched the cause of corner leaks. I found the corner gaskets on Amazon, cheaper for the pair, than GE wants for one. I ordered the set of gaskets and received in GE OEM packaging. I cleaned the corners and installed the new gaskets, all in 5 minutes. Be sure to clean soap buildup from corner before installing for proper seal.  I then ran a test and the leak has stopped.
