GE not draining

My dishwasher is not draining. I do not have an air gap and the disposal is all clear. I’ve tried running the drain hose in to a bucket and no water comes out.
I’ve pulled the washer and verified that the drain hose is not clogged and nothing is blocking the flapper. I do see a small piece of glass inside the pump and there was a 3 inch piece of plastic that I’ve removed. Should I remove the three torque screws from the pump to remove the glass and retest?

How else can I check if the pump needs to be replaced?

Thanks

My Frigidare dishwasher won’t drain

In case anyone else out there is having the same problem, I figured I would update my thread.

I bought a torx screwdriver and removed the cover from the pump. There was a bit of plastic wrapped around the impeller along with a small piece of glass in there. Reconnected everything, and ran a cycle with the drain hose in a bucket to verify that it was pumping out water. Worked like a champ.
