The water stopped running to the ice maker and then to the water dispenser. I did a thorough cleaning underneath. I replaced the water valve assembly with a new one. It is working well. Pushing water through the lines. HOWEVER...it gets to the water filter and fills the filter but the water does not exit the filter to fill the reservoir. We did a thorough trouble shoot....water in, no water out. I had a brita filter that was the replacement for the original culligan. Could this be the problem, or does the head part of the head that the water filter seats into need to be replace? Should I change to another water filter first?
