Water Filter for the Gibson GRS26F5AQ6 (WF2CB)

GRS26F5AQ6 specifics — where the filter actually lives

The GRS26F5AQ6 carries its water filter inside the fresh-food cavity, position varying with dispenser spec — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a quarter-turn twist-in seat: half a turn of wrist work in each direction is the whole procedure; everything else is towel management.

Before you click buy, two things: 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. What pins the parts choice down is the media line: this chassis drinks from the WF2CB family, one of the most cross-referenced cartridges in the Gibson catalog. The Q6 ending is a finish code — color and handle options, not mechanical ones. Every finish of this chassis takes the same cartridge.

Reading the GRS26F5AQ6 model code — what the digits tell you

Read the code as 26 cubic feet of capacity, which tells you the cartridge’s real workload between changes. Filter logic on this chassis: every variant of this chassis locks onto the WF2CB line — that is the whole parts story.

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.
