RWF1052 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it in the fresh-food compartment — exact spot varies by dispenser layout, a deliberate placement that keeps the swap away from the door seals and drawer rails. It is a push-twist bay — the cartridge locks with a short rotation after seating; if it rotates freely, it is not seated.
The recurring owner notes: the reset control is the step everyone skips; the light will not acknowledge a new cartridge on its own. Whatever the badge on the door says, the parts reality is the LT700P line — which is why fit listings key on chassis rather than door style. Read the 52 ending as a revision marker — LG used it for running changes, none of which touched the LT700P bay.
Reading the RWF1052 model code — what the digits tell you
Capacity 10 cubic feet: a mid-to-full-size cabinet whose dispenser traffic sets the realistic change cadence. Shopping shorthand for this model: model-code suffixes track cosmetics; the LT700P fit is invariant across them.
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.

RWF1052 filter questions
LG RWF1052: how do I clear the change-filter light?
Hold the filter-reset control a few seconds after the swap; the status light clears only with a seated cartridge, and the RWF1052 manual maps the control by panel type.
LG RWF1052: bypass plug needed without a filter?
Nothing to buy — the LT700P housing closes without a cartridge; water runs unfiltered until the next one goes in.
Are off-brand filters safe for a LG refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM LT700P cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my RWF1052?
Every six months or at the rated gallon capacity, whichever comes first — the LT700P class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
