So I replaced the filter on this fridge. I was getting water and ice just fine. Followed the instructions, but now there is no water going to the door or ice maker. I tried bleeding the line for ten minutes. When I push the water dispenser switch, I hear it working but no water coming out. I checked the lines, they are empty. I pulled the fridge from the wall and opened and closed the water valve. I took the hose off the valve and opened and closed it again. Lone behold, no water. Why would it not be putting out water all the sudden?

Any ideas? Thanks.
