Product review (5 stars): Difficult to install but cured the leak
I have a 5+ year old dishwasher that starting leaking.  Didn't know why so I thought I'd try changing the seal first.  Have patience when installing the seal; it has to be done slowly to be done right.  It's not difficult per se but there must not be any wrinkles in it or it will continue to leak.  Take your time and you will be rewarded with a leak-free dishwasher like I was.  Very happy with a relatively easy and inexpensive fix.
