Water Filter for the LG LFXS27566S (LT700P)

LFXS27566S specifics — where the filter actually lives

The LFXS27566S carries its water filter top-left of the fresh-food compartment in most French-door layouts, away from the door bins — usually a kneeling-height or shoulder-height swap, not a teardown. This is a push-twist style bay: seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.

Field notes: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. The LF prefix is the tell: when LG stamps LF on the plate it is sorting the machine into the French-door class — same water path, same cartridge, different cabinet. Trailing letters like 6S denote trim and finish: stainless, panel-ready, handle variants. The water path is identical across them.

LF vs LS — what the prefix tells you

The LF prefix sits next to LS in the catalog and the split is cabinet mission: French-door on the LF side, side-by-side on the LS side — the parts catalog runs the same cartridge across both. read the code as 27 cubic feet of capacity, which tells you the cartridge’s real workload between changes.

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.
