Not taking in or putting out water

Not taking in or putting out water

My Keurig slowly started brewing less & less coffee. Finally last night it completely stopped putting any amount of liquid out. Did the paper clip thing and no changes. As far as I can tell it is not taking in any water either. I have been trying to DeScale it all day & it just seems like it is not taken in any water. When I took the lid off of the Water Tank, just to see what was going on, it is putting water back into the water tank. Any other advice?
