Water Filter for the Profile PSW26PSSDSS (MWF)

PSW26PSSDSS specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it in the fresh-food compartment, placement dependent on the dispenser package — usually a kneeling-height or shoulder-height swap, not a teardown. This is a twist-style bay, the friendlier design: seat the cartridge against the o-ring, quarter-turn clockwise, and let the keyed flange do the aligning for you.

Field notes: plan on a towel for the first pull — sitting water in the line — and a five-second reset hold once the fresh cartridge is in. Under the cabinet differences one thing holds: the MWF line — which is why fit listings key on chassis rather than door style. Finish codes such as SS change the look, not the plumbing — order the cartridge by model, ignore the finish letter.

Reading the PSW26PSSDSS model code — what the digits tell you

Cabinet decode: 26 cu ft — the number that tells you whether this cartridge feeds a family-size dispenser or a compact one. The parts catalog sees it simply: the same MWF family covers this chassis end to end.

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.
