Ice maker working, water dispenser not.

Fridge might be old but is working great. All of a sudden the water dispenser stopped dispensing. It came back alive a few days later but then died again.

Ice maker is working and dispensing correctly so I assume the little switch is working correctly. I replaced the filter and also reset the filter and have no reason to assume the water line has stopped working (although - I havent checked yet).

Any ideas?

Thanks!
