Dishwasher Not Draining

Ask this Question: “Has the dishwasher and/or garbage disposal recently installed?” 
If so, it is possible that the knockout plug is still in place on the disposal. 

The knockout plug is located on the disposal where the dishwasher drain hose connects to the unit.	1. Using a hammer and screwdriver, knock the plug into the disposer.	2. Use needle nose pliers to remove the plug.	3. Attach drain hose to disposer inlet with a large clamp. Use pliers to squeeze clamp open and move into position.
