Water Filter for the Crosley CFD28WIB6 (ULTRAWF)

CFD28WIB6 specifics — where the filter actually lives

Where the filter actually lives: upper fresh-food wall in most bottom-freezer builds — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a quarter-turn twist-in seat: release is counterclockwise, seating is clockwise, and the stops are firm enough that you cannot overshoot.

Practical notes from the install forums: 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. Read the prefix and the maintenance writes itself: it usually places the machine in the bottom-freezer family, a strong hint at the cartridge line, the reset behavior, and the service documentation worth consulting. That B6 suffix is trim-level shorthand. Crosley kept the ULTRAWF bay common to every finish in the line.

CFD vs FFUS — what the prefix tells you

The CFD/FFUS pair divides this family by layout — Ordering by prefix works because CFD means bottom-freezer and FFUS means French-door in this catalog — and the cartridge pool overlaps both. Cabinet decode: 28 cu ft — the number that tells you whether this cartridge feeds a family-size dispenser or a compact one.

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.
