Report "No water Hi- my water dispenser suddenly stopped working. I presumed it needed a new filter, so I purchased and installed one. Still no go. I thought perhaps the line got frozen by the filter housing, because there was a bit of ice buildup there from no filter being installed. I used a hair dryer for several minutes to be sure it wasn't frozen, still no go. I've hit the reset on the filter reminder (light was not on, but reset anyway), I've pressed and held the water button for several minutes with no luck, and I've checked the freezer door switch to make sure it is working properly, which it is. I've re-seated the filter several times, but now realize that the water dispenser is supposed to be able to work even without a filter, so obviously something else is wrong. Appreciate any ideas... I'm now guessing maybe it is the valve (is that behind the unit?) thanks"
