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.

How to Check

Disconnect the dishwasher drain hose from the garbage disposal inlet and inspect the connection point on the disposal to ensure the knockout plug has been removed. Use a bucket or large bowl to capture any water that may be in the drain hose when disconnecting the hose from the inlet. The knockout plug is recessed into the inlet and is not visible when looking at it 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.
