RF28HFEDTWW specifics — where the filter actually lives
The RF28HFEDTWW carries its water filter high on the fresh-food side in most French-door layouts — upper back or left wall, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically it is a push-in bay: the cartridge slides onto the header and latches — no tools, no housing removal, five minutes.
The recurring owner notes: a first removal that fights a set o-ring, and a status light that needs a manual hold-to-reset before it acknowledges the new cartridge. The RF prefix is the tell: RF is Samsung’s French-door multi-door designation proper, and the service literature files every one of these under the same cartridge line. WW is finish coding: handles, colors, panel options — none of it reaches the filter bay.
RF vs RS — what the prefix tells you
Same parts shelf, two cabinet missions — Ordering by prefix works because RF means French-door multi-door and RS means side-by-side in this catalog — and the cartridge pool overlaps both. 28 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.

RF28HFEDTWW filter questions
How to reset the water filter indicator: Samsung RF28HFEDTWW?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the RF28HFEDTWW manual’s filter section has the exact control for your trim.
Is a bypass plug required for the RF28HFEDTWW when the cartridge is removed?
Nothing to buy — the DA2900020B housing closes without a cartridge; water runs unfiltered until the next one goes in.
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 RF28HFEDTWW?
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.
