My dishwasher sprays a large quantity of water out the airgap on every wash. I have checked for restrictions. I took the plug off the air gap and the pipe is clean. The hose is clear and I don't see anything in it. It has a y where a hose goes to the pipe that eventually empties out into my sink. One side of the y is connected to the disposal. I'm not sure if that could be where the problem lies. I'm guessing there is a valve in the back of the dishwasher somewhere that is not allowing it to drain properly.

edit: I found some gunk in the disposal pipe that is connected to the air gap. I removed as much as I could with my finger. Could this be the problem? I removed as much gunk as I could. It was suggested to me to pour a bunch of ice and hot water down the disposal to remove any more gunk, but there is a lot less water coming out now. There is still some though.
