Abstract
A water dispensing system for a refrigerator comprising a refrigeration compartment includes a manifold assembly, a monitoring device coupled to the manifold assembly and including at least one sensor, and a filter assembly including a filter housing removably mounted to the manifold assembly. The filter assembly is configured to be compatible with a plurality of suitable filter media. At least two indicators are in signal communication with the at least one sensor when the filter housing is mounted onto the manifold assembly. A controller is operatively coupled to the monitoring device. The controller is configured to identify the filter assembly and the filter medium based on a signal received from the at least one sensor and operate the water dispensing system based on the identification of the filter assembly and the filter medium.
