How long it lasts
Usually every 6 months. The filter light is a reminder, not a water-quality sensor.
After replacing: Press and hold the Water Filter button for three seconds to reset the indicator (LG AU guidance across its filter pages).
Flow slows and taste drops off as the filter fills up. Changing on time is the whole point.
