GE dishwasher not draining

Dishwasher goes thru wash and rinse cycles. After rinsing it stops leaving all the water at the bottom. I cleaned an debris from the bottom of the dishwasher and reran it. The same results. I checked for an air gap and there is non. My sink and disposal are running fine.

What can be wrong?

Thanks

Remove the drain hose from the garbage disposal, put it in a bucket and see how it drains. Check the drain connector at the garbage disposal for a clog. Make sure the drain line is made in accordance with the Installation instructions.
