Product review (5 stars): Problem Resolved
My 20 yr old Maytag dishwasher was leaking BIG TIME.  After researching possible causes I determined it was the gasket...at least that seemed like the easier place for me to start.  I also had to research the number for the part.  (Luckily, I still the original manual AND had written down serial# + model# to help with this. Really surprised myself because I'm not overly organized---understatement).  The new door gasket works and problem resolved!!!!  My old gasket was like a small limp noodle version of this new gasket.  Advice:  make sure to let new gasket soak in warm water x 30 mins to make it more pliable.  Also, since the new gasket is MUCH THICKER make sure the door handle release is depressed when you go to close the dishwasher door.
