Water Filter for the GE GSS22WGMBBB (MWF)

GSS22WGMBBB specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it at the base of the fresh-food compartment in most side-by-side builds — grille or lower rear, the same estate every side-by-side refrigerator in this family uses. It is a twist-lock bay: offer the cartridge, feel the base o-ring register, and lock it by geometry rather than by force.

Two quirks worth knowing before you order: expect the first swap to take longer than the box suggests — aged o-rings grip — so budget ten minutes, not five. One prefix, one chassis family: GSS is GE’s own coding for side-by-side machines, and in that format the water path is long enough that a neglected cartridge shows up as flow drop before it shows up as taste. Trim code BB: cosmetic variants of one chassis, one cartridge family.

GSS vs PSS — what the prefix tells you

Two prefixes, two missions: side-by-side versus Profile side-by-side. Both generations draw from the same cartridge pool, so the prefix is a fit-check, not a barrier. Capacity check: the 22 cu ft in the code is the box size, and bigger boxes push more water through the same cartridge between swaps.

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.
