My dishwasher quit cleaning dishes and lost all pressure. The food screen would keep clogging up and I would have to take it out and clean it by hand. After putting a new impeller in, the "gears" on the impeller connected with the screen blades, the old impeller the "gears" were stripped off. And the new impeller comes with new seals, after taking old one out I noticed it wasn't long before my old seals would have started leaking. Very simple repair if you watch the great video that aplinacepartspros.com has next to the part. The longest part of the job is pulling the dishwasher out and turning it upside down.
