For the second time something has gotten stuck in the grinder.
First time repair man came out and fixed, since it was brand new.
This time we took apart and removed debris. After putting unit back together...spray arms would not spin. Took apart again and now water won't fill. We did fill manually with water and at that point the bottom arm rotated, but not the middle or top and is very noisy .

Check the wash impeller for broken fins.

Check the drain impeller there may still be something in the drain pump.
