Not Draining - Newly Installed - Dishwasher

Possible Solutions

Is the garbage disposer knockout plug removed?

If the dishwasher is connected to a garbage disposer, be sure the knockout plug has been removed from the disposer inlet.

1. Disconnect power to the dishwasher
2. Disconnect the dishwasher drain hose from the garbage disposal.
3. Use a bucket or large bowl to capture any water that may be in the drain hose when disconnecting the hose from the inlet.
4. Inspect the connection point at the disposal to ensure the knockout plug has been removed. 
5. The knockout plug is recessed into the inlet and is not visible when looking at if from the side. Insert a pencil into the inlet and feel for the knockout plug. If the pencil is able to go into the disposer inlet about 3 inches the knockout plug has been removed.
