Water Filter for the Samsung RSG257AAWP (DA29-00003G)

RSG257AAWP specifics — where the filter actually lives

The RSG257AAWP carries its water filter bottom of the fresh-food column or at the grille line in most side-by-side builds, a spot that survives trim changes across the RS run. Mechanically the RSG257AAWP uses a push-in cartridge; the cartridge slides onto the header and latches — no tools, no housing removal, five minutes.

Two quirks worth knowing before you order: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. Decode the plate and the parts question answers itself: Samsung uses it across the side-by-side range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. Trim code WP: cosmetic variants of one chassis, one cartridge family.

RS vs RF — what the prefix tells you

The RS/RF pair divides this family by layout — side-by-side on the RS side, French-door multi-door on the RF side — the parts catalog runs the same cartridge across both. Size class 25 cubic feet — worth knowing because a full household works a cartridge harder than the rated six months assumes.

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.
