Water Filter for the LG LSXS26326B (LT800P)

LSXS26326B specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it low on the fresh-food side or behind the base grille in most side-by-side layouts — usually a kneeling-height or shoulder-height swap, not a teardown. This is a push-twist style bay: the cartridge locks with a short rotation after seating; if it rotates freely, it is not seated.

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. Decode the plate and the parts question answers itself: LG uses it across the side-by-side range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. The 6B ending is a finish code — color and handle options, not mechanical ones. Every finish of this chassis takes the same cartridge.

LS vs LF — what the prefix tells you

The LS/LF pair divides this family by layout — Chassis first: side-by-side (LS) versus French-door (LF). The shared cartridge line covers both without adaptation. the 26 cubic feet figure in the code is the household size proxy; larger households breach the rated gallons before the calendar does.

Swap it in 5 minutes

• Press the release (if fitted), twist the old cartridge free, and pull it from the header.
• Wet the new cartridge’s o-ring with cold tap water so it seats without dragging.
• Push the cartridge square onto the header, then give it the locking quarter turn.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
