Water Filter for the Crosley CFD28WISA (ULTRAWF)

CFD28WISA specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it top of the fresh-food cavity, above the crisper in most bottom-freezer layouts, a spot that survives trim changes across the CFD run. The seat is a twist-in design — release is counterclockwise, seating is clockwise, and the stops are firm enough that you cannot overshoot.

Field notes: expect dribble at the bay on removal even with the supply off, and remember the indicator will not self-clear — hold the reset control. The badge reads CFD28WISA, but the chassis reads CFD: count on CFD to place this unit among bottom-freezer builds; that placement carries the water-path geometry with it. The SA ending is a finish code — color and handle options, not mechanical ones. Every finish of this chassis takes the same cartridge.

CFD vs FFUS — what the prefix tells you

Prefix families here: CFD against FFUS. bottom-freezer on the CFD side, French-door on the FFUS side — the parts catalog runs the same cartridge across both. 28 cu ft of cabinet — the dispenser sees heavy traffic at that size, and heavy traffic ages cartridges faster.

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.
