Dishwasher Will Not Drain – High Drain Loop Installation

If dirty or smelly water enters the dishwasher between cycles or water pumps out of the dishwasher during the wash cycle, the cause could be because there is neither an air gap nor a high drain loop installed. GE dishwashers require either an air gap or a high drain loop to prevent these issues from occurring.
Look to see if an air gap is installed and that the dishwasher is properly connected to it. If there is no air gap installed check to see if there is a high drain loop in the drain hose of the dishwasher. A high drain loop is formed by the drain hose being fastened to the underside of the counter top.

This performs the same task as an air gap, but is much easier and less costly to install.
