Water Filter for the Profile PIE23NGTIFSV (MWF)

PIE23NGTIFSV 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. Mechanically the PIE23NGTIFSV uses a twist-in cartridge: the bay wants the cartridge offered flat, rotated a quarter turn, and nothing more — hand pressure only.

The small print owners learn the hard way: the reset control is the step everyone skips; the light will not acknowledge a new cartridge on its own. Whatever the badge on the door says, the parts reality is the MWF cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike. Trim code SV: cosmetic variants of one chassis, one cartridge family.

Reading the PIE23NGTIFSV model code — what the digits tell you

Read the code as 23 cu ft of capacity, which tells you the cartridge’s real workload between changes. The model code varies with trim, but the parts logic does not: the water path is fixed at the MWF line — that asymmetry is what makes filter shopping simple.

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.

What this filter takes out of your water
