Water Filter for the Hotpoint HSH25IFTAWW (MWF)

HSH25IFTAWW 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, a spot that survives trim changes across the refrigerator run. Mechanically the HSH25IFTAWW uses a twist-in cartridge: 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: flush before the first glass — new carbon beds shed fines for the first gallon or so, which is cosmetic, not contamination. What pins the parts choice down is the media line: the MWF cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike. Trim code WW: cosmetic variants of one chassis, one cartridge family.

Reading the HSH25IFTAWW model code — what the digits tell you

25 cubic feet of cabinet — the dispenser sees heavy traffic at that size, and heavy traffic ages cartridges faster. Hold this constant while shopping: whatever the door count, the cartridge answer for this chassis is the MWF family.

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.
