My four year old Kitchenaid dishwasher (KDTE334GPS0) was previously absolutely silent, we had to feel it to tell if it was running. We recently had our water heater go out so we were without hot water for a week but we still ran the dishwasher - maybe unrelated but thought I'd mention it. Now the dishwasher makes an intermittent groaning/humming sound during the wash cycle. It appears as if the lower spray arms are not getting any water and not spinning. The upper arm is still getting water and the top dishes are getting clean. Reading other threads has led me to suspect the Diverter motor. I'm having trouble locating the tech guide for this model. Is there a way to run diagnostics to tell what is wrong before I start buying and replacing various parts? Any suggestions on how to determine if this is the cause? I have removed the spray arm, it does not appear to be clogged or damaged.
