RS261MDWP specifics — where the filter actually lives
The RS261MDWP carries its water filter at the base of the fresh-food compartment in most side-by-side builds — grille or lower rear — usually a kneeling-height or shoulder-height swap, not a teardown. This is a push-style bay, the simplest geometry there is: the latch does the locking for you; your only job is keeping the cartridge square on the way in.
Before you click buy, two things: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. RS is not a trim code, it is a chassis statement: the RS run is Samsung’s side-by-side series; across the run, the filter bay is one of the constants. Finish codes such as WP change the look, not the plumbing — order the cartridge by model, ignore the finish letter.
RS vs RF — what the prefix tells you
The RS prefix sits next to RF in the catalog and the split is cabinet mission: side-by-side builds carry RS; French-door multi-door builds carry RF. Filter-wise the two lines converge on one cartridge family. 26 cubic feet of cabinet — the dispenser sees heavy traffic at that size, and heavy traffic ages cartridges faster.
Swap it in 5 minutes

- Pull the old cartridge straight out of the header — expect a small spill, not a flood.
- Align the new cartridge with the keyed slot; it only goes in one orientation.
- Push the cartridge home until the retention latch clicks.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

RS261MDWP filter questions
Clearing the filter status light on a Samsung RS261MDWP?
Hold the filter-reset control a few seconds after seating the new cartridge; placements vary by control panel, and the RS261MDWP manual’s filter-status page has the exact spot.
Running the RS261MDWP with an empty filter bay — does it need a cap?
The bay self-seals: with no cartridge the RS261MDWP still dispenses, just unfiltered. No bypass plug exists for this line.
Are off-brand filters safe for a Samsung refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM DA2900020B cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my RS261MDWP?
Every six months or at the rated gallon capacity, whichever comes first — the DA2900020B class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
