Water Filter for the LG LSXS26326W (LT800P)

LSXS26326W specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it bottom of the fresh-food column or at the grille line in most side-by-side builds, so expect to clear one shelf edge before you have working room. The seat combines push-fit and twist-lock: seat the cartridge, give it the quarter turn, and the bay takes it from there.

Owners of the LSXS26326W report the same friction points: carbon fines in the first pours are normal for a fresh bed, and the filter timer only restarts when you hold the reset. The LS prefix is the tell: 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. 6W is finish coding: handles, colors, panel options — none of it reaches the filter bay.

LS vs LF — what the prefix tells you

Same parts shelf, two cabinet missions — LS answers to side-by-side; LF answers to French-door; the water-filter answer is shared. The digits in the model number read as cabinet capacity (26 cu ft), a decent proxy for how hard the filter works in daily service.

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.
