Product review (3 stars): For random leaking, DO THIS FIRST!  Check water level float!
Our old Maytag dishwasher was leaking occasionally, so we ordered this.

The original door seal was soft compared to the much firmer new one, and seemed intact.
Installation was easy, just pull out the old one and push in the new one.

After installation it was obvious that fully closing the dishwasher door would now require much more effort.

HOWEVER- after the first leak-free wash cycle we would have random leaks.  On a guess, I felt around underneath the tophat shaped float that tells the washer when it is full enough to begin the cycle.  In our Maytag the float is at the bottom on the left side in the washer as you are facing it.

The inside of the float was packed with greasy, congealed gunk, and the extra weight plus friction was causing the float to stick in the down position and making the washer overfill with water.

I wiped around under the float and pulled out over a 1/4 cup of goo.  Since cleaning the float we have had no more leaks.  We probably didn't need to replace the door seal.
