Replace the water filter:
Approximately every six months.
When the Water Filter indicator lights up.
When the water dispenser output decreases.
When the rated gallons of water have been dispensed.
To purchase a genuine replacement water filter:
Visit your local dealer or distributor
Search using "water filter" on lg.com
Use replacement cartridge: LT1000P, LT1000P*, LT1000PC, LT1000PCS or ADQ747935**
Remove the door bin.
Remove the disposable water filter.
Replacing the water filter causes a small amount of water (around 1 oz. or 25 cc) 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.
Replace the door bin.
After changing the filter, press and hold the Water Filter button for three seconds to reset the indicator light.
After the water filter is replaced, dispense 2.5 gallons (10 liters) of water (flush for approximately 5 minutes) to remove trapped air and contaminants from the system.
Do not dispense the entire 2.5 gallon (10 liters) amount continuously. Press and release the dispenser pad for cycles of 30 seconds ON and 60 seconds OFF.
LG strongly recommends that you use LG-authorized water filters to prevent water quality issues, water leakage and appliance malfunction.
