Replaced the water filter, but that didn't work. From researching online thought it might be the water filter head. The part ordered includes the water filter head as well as the water reservoir. Part received with no instructions. Had to remove all refrigerator internal shelves to get to panel at back of refrigerator. Removed water filter cover, and two panels at back of interior of refrigerator. Also had to unfasten water supply behind refrigerator. Once all this was done, was able to remove the old water filter head and reservoir. Also had to disconnect one hose from the water filter head to a valve that I was not replacing. Connected new part using reverse procedure. This has completely corrected the issue of low water flow from the water dispenser.
