Ice-Maker and Water Dispenser not working.

First I disconnected the power cord, then removed the screws that held the bracket that holds the base for the water-filer in place. I then disconnected the water lines(intake and outflow). Next I removed the screws that held the water-filter's base in place. I then disconnected the release lock mechanism for the filter and finally removed the water-filter base. I did the reverse to install the new water-filter base. Previously I had tested the intake water line and noticed the water was flowing with enough pressure upto the water-filter's base but no water was exiting thru the outflow line, which leads to the Ice-Maker and Dispenser. I had tried changing the filter but that didn't solve the problem it was then I had realized that the Base was the problem. The actual problem was the spring-loaded valves for both the intake and outflow lines, which had a plastic prong that protrudes out of the base that is triggered by the filter when installed. The two prongs were worn-down so the filter wasn't activating the spring-loaded release valve to let the water thru. As for the light, I just unscrewed it.
