Hi everyone, first time poster here.
Two days ago we noticed a harsh buzzing noise coming from beneath our KDTE704DSS0 dishwasher. The sound comes on for around 20 seconds after about 10 minutes of a normal wash cycle, and then after another ~5 minutes it comes on and stays on.

Quick video of the sound



After doing some research on this Forum, it doesn't seem to be the drain pump (no noise during draining); the wash cycle pump (I felt the pump rubber elbow expand during pumping with no noise); or the detergent solenoid (detergent opens fine and the sound is definitely coming from the bottom of the washer.

I think it might be the diverter motor part as the rotating spray arms don't seem to have been running when I open the door mid-wash, and there is a small leak beneath the diverter motor.

Any thoughts or advice before I bite the bullet and order a new diverter motor?

Yes, it sounds like a bad diverter motor, but I'd also check the diverter disc to see if its worn out.

Does the diverter disc look worn out(wallowed out in the middle) where the diverter motor shaft connects to it?

Watch this video below, it shows you how it goes on the shaft: https://www.repairclinic.com/Repair...id-Dishwasherdiffuser-Replacement-Wpw10476221

If so, then just order the new diverter disc(aka diffuser):
Diffuser WPW10476221


If not, then order the new diverter motor, it comes with a new diverter disc:

Can't thank you enough Jake for taking the time to reply. Much appreciated!

I checked the diverter disc and it was very secure with the diverter motor shaft. My next step was to unplug the diverter motor wiring and run a cycle. Sure enough, the noise has stopped. Diverter motor part is on its way and I'll be replacing it ASAP.

Thanks again!

Sorry for the very tardy reply. I ordered the cheaper diverter motor from Amazon that came with the rubber gasket. I took out the old (leaking) gasket and replaced it with the new one, which was obviously not as high quality. However, with a liberal application of plumber's grease, the dishwasher is leak-free and back to being quiet.

Thanks again for your help Jake!
