Also, I always clear all food before putting something into the dishwasher.
Any suggestions as I've never taken apart a dishwasher before but I can follow instructions. I would rather try and do it myself than pay a repair person.
I have the same model GE dishwasher and the same symptom. To me, the "grinding" noise might be better described as a vibrating, low pitch growling noise that is only present during the wash cycle. Almost like a spray arm is vibrating or hitting something when it spins. The vibration (noise) is not always present. Sometimes, it will go through a complete cycle and not make the noise.
I checked to see if the washing arms are hitting anything and found nothing.
I can sort of re-create the growling noise when I spin the lower arm with my hand. It does not always spin smoothly, it will sort of wobble and vibrate creating a similar growling noise as it turns.
I have removed the lower spin arm and found nothing unusal.
Other then the vibration, low pitched gowling noise, the machine works perfectly.
