Quick Answer: How Do You Replace a Samsung Refrigerator Water Filter?
Shut off the water supply, turn the old filter counterclockwise to unlock it, and pull it out. Insert the new filter and turn it clockwise until it locks, then reset the indicator, turn the water back on, check for leaks, and flush. Exact steps vary by model.
Not sure how to replace your Samsung water filter? A few standard steps apply, though some vary by model, so check your manual if yours looks different. If your filter light has turned red or a similar alert appears, it's time. Samsung recommends replacing the filter every six months.
Samsung's US instructions begin by shutting off the water supply to the refrigerator. The valve is often under the sink, behind the fridge, or under the house, and valve types vary. Dispense water until the flow stops to relieve pressure. A few models' instructions skip this step, so read yours first.
Location varies by model: the upper right corner inside the fridge, between or near the crisper drawers, or an external filter on the water line behind the unit. Open the cover if there is one, turn the old cartridge counterclockwise (usually a quarter turn), and pull it straight out. The Samsung DA29-00003G is in the upper right corner and requires pulling the filter down out of the socket. Check your box’s instructions if the mechanism looks different.
Confirm the new filter matches the old one's model number or your refrigerator's requirements, since Samsung uses several cartridge types. Remove the protective cap and any packaging. Buying genuine? Check the packaging for Samsung's authenticity check before installing. Some models provide a tag and magnet to do this. Compatible SpiroPure filters are made to OEM specifications, with certification to NSF standards, at a lower price.
Insert the filter and turn it clockwise until it locks. On HAF-CIN and HAF-QIN filters, the LOCK symbol on the cap should line up with the indicator line on the compartment. HAFCU1 filters twist right until the notch lines up with the arrow on the housing. Don't force or overtighten.
Reset the indicator now, while the water is still off. On most models, hold the Filter Reset button for 3 seconds. Some are labeled Alarm, Water Filter, or Ice/Water or there might be a symbol. Others use a button combination or a menu, like the Family Hub Fridge Manager mobile application or “app” so you can check this step off from the comfort of your phone. Our Samsung filter reset guide covers model-specific steps.
Turn the water supply back on when applicable and check the housing and surrounding area for drips. If it leaks, confirm the cartridge is fully seated and the lock lines up rather than forcing or overtightening it. Samsung's troubleshooting guides suggest inspecting the filter and housing when leaks occur.
Dispense and discard water to clear air and loose material from the system. Use a large container. Samsung's guidance varies, from a noticeably specific 7 minutes of dispensing to 2–3 gallons (as with SpiroPure models), so follow the instructions for the filter in your hand.
Don't choose a filter by appearance alone. Many filters look alike. But slight variations in connections and locking tabs will prevent filters from fitting. Samsung uses several cartridge types, so verify your refrigerator's model number or the part number printed on your current cartridge. Samsung's support pages say the same: check the model number on your old filter to see which type you need. HAF-CIN, HAF-QIN, and HAFCU1 are common examples, though yours may differ.
