Kitchenaid dishwasher leak

Hello, I have a Kitchenaid KDTM404ESS3 which is a few years old. It started leaking and I removed the bottom access panel. I observed it dripping from the “Pump Diverter Motor”. When I removed the dishwasher, it looked like it was leaking from the part where that motor goes into the dishwasher.

I removed that motor and it doesn’t look like there is a seal of any sort to prevent leaking. Do I need to replace the whole plastic base that motor mounts to? Pictures are in the link below
