Water Filter for the Profile PSIC3RGXCFCV (MSWF)

PSIC3RGXCFCV 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, so expect to clear one shelf edge before you have working room. Mechanically the PSIC3RGXCFCV uses a twist-in cartridge: seat the cartridge against the o-ring, quarter-turn clockwise, and let the keyed flange do the aligning for you.

Before you click buy, two things: the change light ignores the new cartridge until you reset it, and the first removal always takes more muscle than the manual implies. The PSI in PSIC3RGXCFCV is doing real work: it usually marks a Profile side-by-side layout, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts line. That CV suffix is trim-level shorthand. GE kept the MSWF bay common to every finish in the line.

PSI vs PSK — what the prefix tells you

Catalog distance, parts proximity: PSI/PSK sit apart in the brochure, together in the parts catalog. One more anchor for the parts search: this chassis drinks from the MSWF family, one of the most cross-referenced cartridges in the GE catalog.

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.
