I have run into this several times, in my house, and others. The 7/8 inch rubber drain hose from the air gap to the garbage disposal kinks. This usually results when the air gap has been located close to the disposal, but requires several bends to connect it. The disposer cannot be rotated, due to the connection to the drain. What gets me, is that they sell corrugated flex drain hose in 6ft lengths from the dishwasher to the air gap, but I can only find the thick rubber hose (7/8") for the air gap to disposer, which is prone to kinking. The hose is only about 10" long, and installing a longer hose doesn't help.

Use 3/4" copper elbows to reroute the hose. DO NOT make the hose longer or you will create additional problems. It should be as short as possible.
