Install, flush and reset
The appliance manual remains authoritative when model-specific instructions differ.
- 01
Locate the existing cartridge and note its orientation before removal.
- 02
Install only the exact cartridge family confirmed for the refrigerator model.
- 03
Flush and reset the filter indicator using the refrigerator manual for the exact appliance model.
Flush
LG’s exact instructions can vary by refrigerator. The LT1000P support sequence calls for flushing approximately 2.5 gallons or about five minutes.
Indicator reset
On supported LG controls, press and hold the Water Filter button for approximately three seconds after replacement. Verify against the exact refrigerator manual.
Before you buy
A compact check designed to catch the expensive mistakes.
- Match the complete refrigerator model number, including suffix characters.
- Match the canonical part number or an explicitly listed superseded number.
- Review the exact performance data sheet for the contaminants that matter to your household.
- Check package condition and seller identity before installation.
Research note: Certification to a standard does not mean every claim in that standard applies. Only exact-model claims should be relied on.
