Leaking Water Dispenser

This is a brand new Kitchen Aid refrigerator. The water dispenser leaks anywhere from 2 drips to a couple of dozen drips. This problem is being caused by air entering into the water system somewhere. You can tell that it is air in the system by the little ‘spurt’ that you can see about 1/2 a second into the video. This air bubble happens every time the water dispenser paddle is pushed. I traced the air bubbles back as far as the tank in the fresh food section – I can see bubbles entering the tank when I call for water. This eliminates everything after the water tank as the source of the air. The parts left are the water filter, filter housing, water valve and interconnecting tubing. I’m leaning toward the filter housing being the problem, so I will try that first.
