Water Filter for the GE GSS25PGMABB (MWF)

GSS25PGMABB specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it bottom of the fresh-food column or at the grille line in most side-by-side builds, a deliberate placement that keeps the swap away from the door seals and drawer rails. This is a twist-style bay, the friendlier design: no tools, no housing removal, and the cartridge indexes in only one orientation despite looking symmetric.

Two quirks worth knowing before you order: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. Prefix literacy pays here: GE 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 BB: cosmetic variants of one chassis, one cartridge family.

GSS vs PSS — what the prefix tells you

The GSS/PSS pair divides this family by layout — Ordering by prefix works because GSS means side-by-side and PSS means Profile side-by-side in this catalog — and the cartridge pool overlaps both. cabinet class 25 cubic feet — a box that size leans on the dispenser, so the six-month cartridge interval earns its keep.

Swap it in 5 minutes

• Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
• Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
• Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
