Water Filter for the Samsung RM257ABBP (DA29-00003G)

RM257ABBP specifics — where the filter actually lives

On the RM257ABBP, the cartridge inside the fresh-food cavity, position varying with dispenser spec — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a push-in bay: the cartridge slides onto the header and latches — no tools, no housing removal, five minutes.

Order-day practicalities: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. Whatever the badge on the door says, the parts reality is the DA2900003G cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike. That BP suffix is trim-level shorthand. Samsung kept the DA2900003G bay common to every finish in the line.

Reading the RM257ABBP model code — what the digits tell you

The 25 cu ft figure in the code is the household size proxy; larger households breach the rated gallons before the calendar does. Fit listings tell the same story: the RM257ABBP family shares one water path, so the DA2900003G cartridge fits the entire run.

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.
