The filter must be changed every 6 months or when the water filter indicator on the control panel lights turns on or the water dispenser output decreases.
To purchase a replacement water filter:
Use replacement cartridge: LT1000P, LT1000PC, LT1000PCS or ADQ747935**

Remove the door basket.

Remove the disposable water filter.

Replacing the water filter causes a small amount of water to drain.
Wrap a cloth around the front end of the water filter cover to collect any leaking water. Hold the water filter upright, once it is removed, to prevent any remaining water from spilling out of the water filter.
Replace with a new water filter. Insert the new filter into the filter head and rotate it clockwise until the arrow on the new filter lines up with the arrow on the filter head. Swing the filter back into the compartment.

Refit the door basket.
Press and hold the Water Filter button for 3 seconds to reset the water filter indicator.
Dispense water for approximately 5 minutes to remove trapped air and contaminants.
Failure to replace filters when required or using non LG authorised water filters can cause the filter cartridge to leak and result in property damage.
