What to Check First

  2. Check the filter sooner if water dispenses slowly or the Water Filter Replacement indicator turns on.

  7. Filters typically last about 6 months, but your household's water usage and quality may require sooner replacement.
  8. Check the label on your existing filter or use your refrigerator model number to find the correct replacement.
  9. Common LG water filter models include LT500P, LT600P, LT700P, LT800P, LT900X3, and LT1000P.
  10. The filter's location and installation method depend on your specific refrigerator model.
