Plastic parts on this Kitchenaid dishwasher suffer repeat wear problems from heat and chemical detergents. The retainer nut on the bottom wash arm split horizontally int the thread area, and during operation, the wash arm would rise up and hit the bottom of the lower basket so there was a worn groove in the wing on top of the nut and the dishes weren't getting very clean. Simple replacement, just screw the nut down. Also decided to replace the bearing ring right under the wash arm because it was getting pasted with white crust-like material from hard water and chemical detergent residues. I've dealt with PartSelect twice now, and they are fast and efficient. The online parts breakdowns are easy to follow.
