Spouse complained that the dishes in the lower rack were not getting clean. She opened up the dishwasher mid-cycle to find that the lower jets were not working. I looked in and found a "sludge" coming through some of the nozzles. Removed the lower washer arms. These are the kitchenaid dynamic wash arms driven by a motor. I noticed more of the sludge throughout the machine, in the tracks, etc.. On review it looked like it was inside the arms so I took them apart. It doesn't look like the arms are meant to be serviceable, but just about everything can be if you try hard enough. I would post pictures, but it wasn't pretty. I had to use a dish brush to clean everything off. Took out all the plastic parts throughout the entire machine and cleaned them all out. The stuff was throughout the entire sprayer system. The best I can tell is that a heavy load of pasta made it into the dishwasher and was "distributed."
I put my GoPro in during a rinse only cycle to make sure all the jets were working well. Everything was flowing appropriately other than the washer arm not rotating. It looks like it wants to rotate, stutters along, and then stops. My first thought was that I broke it. The main part I removed is just a garnish that covers the gears on top. I verified everything was moving freely and the main drive gear ring was secured tightly.
On review the washer arm popped off the cover. After lots of experimenting it still wouldn't work. I took the washer arms off and used the gopro again to see if the motor was turning the gear that turns the washer arm. I did this during a diagnostic cycle. It looks like the gear is turning well and consistently. The gear on the bottom of the washer arm looks good. The gear from the motor looks good. What looks worn is the cover for the motor. Pictures included.
There were no error codes after the diagnostic cycle.
