Kenf for Model Number KDPE234GPS0 Food residue being left on dishes, which got me to trouble-shooting. Lower spray arm does not appear to be spinning/supplied with water. (Position noted; run for ten minutes; position unchanged.) If I am understanding the diagrams correctly, the diffuser/diverter controls whether water is supplied to lower spray arm or middle/upper spray arm, depending on position of the diffuser/diverter disc and its opening. In other words, the diffuser/diverter disc allows water to flow out of one port of the cover or the other, but water does not flow out of both -- and hence to the lower and middle/upper spray arms -- simultaneously. IS THIS UNDERSTANDING OF THE DRAWINGS CORRECT? Assuming this understanding is correct, how frequently is the diverter motor supposed to turn the diffuser/diverter from one position to the other? Every time I open the dishwasher while testing things and find the lower spray arm has not changed position, I pull the spray arm off and reach down into the port in the cover and find that port still blocked by the diffuser/diverter disc. This would be consistent with lower spray arm not getting any water, which would help explain dishes not getting cleaned. BASED ON THIS, I BELIEVE THE DIVERTER MOTOR IS SHOT. DO YOU AGREE?
