I have a Whirlpool Refrigerator model ED5VHEXVB00 and right now I have a low water pressure coming out of the water dispenser. The water filter needed to be replace this month and the light just turned red so I bought one and replaced it thinking that this might have something to do with the problem. After replacing the water filter I still have the same problem. Water pressure is very low and is making very thin ice cubes.
Many times the problem you are describing comes from a saddle valve a small valve that punches a hole in the existing pipe. These valves are notorious for getting plugged and leaking. The best fix would be to install a T And a shut off valve at the location because in a few months or years most saddle valves start leaking.
