Water dispenser isn't working

My Samsung Bespoke fridge will auto-fill the pitcher, and it will make ice, but will not dispense water. I have checked the water line and the filter, and both are fine. I assume the water line isn't frozen because the pitcher and ice still work fine. I'm having a hard time finding a diagram for how and what to repair.

FIXED: I had a repair person out and he told me that they way he fixed it was to disassemble the valve and reassemble it. He figures there is an air bubble that gets inside and the only way to get it out is to disassemble the valve. He said mine was the third one that had the same issue, and it's been the fix every time.
