Reset the filter light for HAF-CIN/EXP
Reset only after a successful replacement and stable water flow. The published Samsung record identifies this cartridge as HAF-CIN Refrigerator Water Filter.
Start with fit verification
Match the complete refrigerator model and the code printed on the existing cartridge. Genuine Samsung filter. HAF-CIN and HAF-QIN are different filter types; match the code printed on the existing filter or use Samsung's finder. Do not infer compatibility from color, overall shape or brand alone.
Service baseline
The available record uses 6 months or 300 gallons, subject to the manufacturer’s whichever-comes-first instructions. Water quality, usage and long periods of inactivity may justify earlier service.
Safe action
Turn off the water supply, unlock the old filter counterclockwise, insert the new filter and turn clockwise until locked. If the cartridge does not seat normally, water does not return after flushing, or the housing leaks, stop and use the refrigerator’s model-specific manual.
Evidence
Open the linked source before purchase. FilterRef separates published compatibility from general troubleshooting guidance and does not treat an aftermarket cross-reference as automatically equivalent.
