I believe the actual problem was the water inlet valve; however, since this is a built in refrigerator with the water shut off inconveniently located behind the refrigerator, I attempted to buy some time by plugging the water dispenser outlet tube. That was a mistake. Eventually enough pressure built up and actually blew out the anti-drip valve at the water dispenser. That "valve" appeared to be a plastic bag that was supposed to reduce dripping at the outlet tube. Perhaps it didn't function well since apparently it is no longer manufactured. So now I not only need to replace the water inlet valve, but also the dispenser tubing. The primary issue in my case was getting enough clearance beneath the refrigerator to make the repairs. Ultimately I had to pull the refrigerator out and raise it up on 2x4s to get enough clearance. In my case, in order to feed the new dispenser tube I used electrical tape to tape the new tubing to the old tubing before I pulled the old tubing out through the dispenser. I also replaced the water inlet valve (ordered from a different company). The video on your website is helpful as a general guide for replacing the water dispenser tubing; however, since my Kitchenaid built in refrigerator is different from the model in the video, I had to figure out things that were specific to my model.
