KitchenAid KRSC503EBS01 water dispenser generating a “noise” and won’t dispense water. Remove the filter and it works fine. Replaced filter, still a problem. Does it sound like the Valve-Dual needs replacing?
Since removing the filter allows the water dispenser to work properly, the filter housing is the cause of failure. The built-in bypass is not seating fully when the filter is installed, which blocks water flow.
