Dishwasher Not Draining Properly Once the rinse cycle is complete and the draing cycle starts, the water begins draining through the Air gap. I have the hole in the air gap cover pointed towards the sink, so that is where the water is coming out. What causes this? I checked the line from the air gap to the disposal and it is clear.

On many Dishwashers at the bottom ( remove lower rack ) is usually a metal mesh screen Under that screen is the pump inlet .When the screen gets clogged up or even restricted .It will either slow drain ,and or spit it out the breather hole on the air gap .So i think the issue is inside the dishwasher .If its a newer SS tub Then the mesh screen should be metal .However if its plastic then it will be a plastic screen Hard water deposits along with food particles can clog the pump screen
