Product review (4 stars): Dishwasher Tub Gasket
Make sure you ordered the right one, I did and it worked great. Replaced the original which had swelled and was covered with gunk from the washer. Was a snap to put in, just pull out the old one, clean the seal track and bottom of the washer where the junk built up under the washer. Soak new washer in hot water for about 15 minutes, and install. Works great, and got rid of a weird smell that used to come out of the washer. If you are a do it your self-er this is a bargain. There is a video how-to on YOUTUBE.
