Maytag Dishwasher-pdb2430awx-Leaking

I believe that you must buy the plastic pump housing.....And that vinyl type shaft seal comes with that..I think!!!!
I have the same problem.....I changed the regular seal kit at a cost of $30.00 CND....Which is like what? 100.00 American.
Anyways mine still leaks after all that. Turns out there is so much rust between the nylon seal that is attached to the motor shaft, that water works its way down there. Funny that seal does not come with the common seal replacement kit. Im going to check tomorrow to see If I can get that seal alone. My concern is that after I drive for another hour one way to get that seal. Am I only going to put it on just to find out that the shaft is pitted to much by the rust to seal again? I am so tired of buyin ****!!!!!!
