Maytag won't drain

When we wash dishes water stays in the bottom of the tub. I have disconnected the drain hose and blown air back thru the drain hose and made bubbles in the water in the dish washer so I don’t think the drain is blocked. Help please !!!

what happens when you put the unit into drain and let the waste hose sit in a bucket ?

I can hear the pump running but nothing is coming out of the drain hose.
