My dishwasher was leaking out the bottom, and by pulling it out and running a cycle I quickly saw it was from the diverter shaft. Since this seal is glued into the sump, I ordered a sump which comes with the new seal installed. The only difficult part was compressing the main sump seal into the dishwasher housing--I basically had to climb inside the unit and use my body weight to get it to seat properly. Note that at least one additional clamp is required since the original pump hose clamps on the high pressure side are one-time-use crimp clamps. This site helped me prepare and order the parts I needed so I didn't have to wait for multiple orders.
