Water Filter for the LG WFC2001 (LT600P)

WFC2001 specifics — where the filter actually lives

On the WFC2001, the cartridge in the fresh-food compartment, placement dependent on the dispenser package, so expect to clear one shelf edge before you have working room. The seat combines push-fit and twist-lock: the cartridge locks with a short rotation after seating; if it rotates freely, it is not seated.

Order-day practicalities: the change light ignores the new cartridge until you reset it, and the first removal always takes more muscle than the manual implies. Whatever the badge on the door says, the parts reality is the WFC2001 shares its water path with the whole LT600P generation — the cartridge is the common denominator, not the door count. The two-digit 01 tail is revision bookkeeping. Badge position and shelf trim moved around; the bay geometry did not.

Reading the WFC2001 model code — what the digits tell you

Call it a 20 cu ft box — which is why this cartridge works for a living rather than sitting decorative. The parts catalog sees it simply: the LT600P cartridge is the one constant across the model run.

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.
