KitchenAid KDPS424S Third Rack Dishwasher Repair

The KDPS424S combines 360-degree Max Jets with a third rack and a ProDry system, and a KDPS424SPS plate refers to the same machine. With jets spread across several levels, a single clog can leave one area visibly dirty.
We trace the water path from filter to arms, clearing every jet we can reach, then confirm the third rack tray slides freely on its rails. Drying problems prompt a check of the fan and vent.
A written price is given before any work, and our repairs include a 30-day workmanship warranty. With so many openings, we also check that each arm turns freely by hand before and after cleaning. The third rack tray should glide on its rails without catching, and the seals where water reaches it should stay dry during a cycle. Everything gets a final test run before we leave.
A clogged jet or a stiff spray arm is typical. We clean the jets, check the arm, and confirm the filter is not restricting flow.
Not necessarily. We check the fan and vent first, since blocked airflow keeps moisture in the tub. If air moves normally, we test the heat side.
The rails or wheels on the tray may be worn or dirty. We clean and inspect them, replacing any worn parts so the rack moves smoothly under load.
