The unit makes a noise like it did when the water dispensed, but it just won't give water. I've changed the filter. Ice maker works fine. Just no water.

There is a heater filament that keeps the hose from freezing when it runs through the freezer. Turn on the dispenser light and leave it on all day. It should be enough to melt the ice in the dispenser. Try it again at the end of the day and if it works there is your problem.
