I've been trying to get my Kitchenaid dishwasher - KDTM404KPS0, back up and running. Initially, it would fill and drain, but would not circulate water. I replaced the Dishwasher Pump Assembly (W11416362), and now water is circulating, but only on the middle arm. What am I missing, thanks!

I'm also getting the 10-4 code now and I've noticed that the white disc in the diverter is covering outlet during wash cycle. I'm assuming that it's stuck in the wrong position and not moving???

You could try to test your diverter motor to confirm before purchasing a new one:



My diverter recently failed, but it spun just fine. There's a little button inside the diverter unit that failed on me (which allows the software to know when the diverter changes position). With that failed part, the software constantly spun the diverter waiting for a button click that never came (I could hear the water in the dishwasher constantly cycle through the various spray levels).

Appreciate that. I was thinking the same thing and ordered one on ebay - fingers crossed!

Good luck!

The one I ordered came with a new grommet, and I put a touch of lubricant between the shaft of the new diverter and the new grommet (because my old one also leaked slightly - I assume the constant turning/rubbing might have worn it out).
