I changed the water valve and there is still no water. Is there a valve at the dispenser keeping me from dispenseing water. I cannot get behind the door panel because it looks like it is molded into the front of the door. Is there a diagram of the water line that I can look at or can you tell me how to get to the water line behind the door. I have tried to blow out a clog if there was one and to no avail, it did not work. I can snake a wire up so far from the coupler connector at the bottom and it only goes so far. HELP ME PLEASE. I also need the part number to the coupler at the bottom since one side of the coupler now comes off when I try to dispense water. Again HELP ME PLEASE...
