About the GE ^® MWF water filter cartridge
Water filter cartridge
The water filter cartridge is located in the back upper right corner of the refrigerator compartment.
When to replace the filter on models with a replacement indicator light
There is a replacement indicator light for the water filter cartridge on the dispenser. This light will turn orange to tell you that you need to replace the filter soon.
The filter cartridge should be replaced when the replacement indicator light turns red or if the flow of water to the dispenser or icemaker decreases.
When to replace the filter on models without a replacement indicator light
The filter cartridge should be replaced every six months or earlier if the flow of water to the dispenser or icemaker decreases.
Removing the filter cartridge
If you are replacing the cartridge, first remove the old one by slowly turning it to the left. Do not pull down on the cartridge. A small amount of water may drip down.
CAUTION: To reduce the risk associated with property damage due to water leakage, read and follow instructions before installation and use of this system. Installation and use MUST comply with all state and local plumbing codes.
Installing the filter cartridge
1 Fill the replacement cartridge with water from the tap to allow for better flow from the dispenser immediately after installation.
2 Line up the arrow on the cartridge and the cartridge holder. Place the top of the new cartridge up inside the holder.
Do not push it up into the holder.
3 Slowly turn it to the right until the filter cartridge stops. DO NOT OVERTIGHTEN. As you turn the cartridge, it will automatically raise itself into position. The cartridge will move about a 12 turn.

4 Run water from the dispenser for 1-1/2 gallons (about three minutes) to clear the system and prevent sputtering.
5 Press and hold the RESET WATER FILTER pad (on some models) on the dispenser for three seconds.
NOTE: A newly installed water filter cartridge may cause water to spurt from the dispenser.
Filter bypass plug
You must use the filter bypass plug when a replacement filter cartridge is not available. The dispenser and the icemaker will not operate without the filter or filter bypass plug.

To use the filter bypass plug on Water by Culligan™ models, you must first remove the filter adaptor from the cartridge holder by turning it to the left.

WARNING
To reduce the risk associated with choking, do not allow children under 3 years of age to have access to small parts during the installation of this product. The disposable filter cartridge should be replaced every 6 months at the rated capacity, or sooner if a noticeable reduction in flow rate occurs.
For the maximum benefit of your filtration system, GE recommends the use of GE-branded filters only. Using GE-branded filters in GE and Hotpoint® refrigerators provides optimal performance and reliability. GE filters meet rigorous industry NSF standards for safety and quality that are important for products that are filtering your water. GE has not qualified non-GE-branded filters for use in GE and Hotpoint refrigerators and there is no assurance that non-GE-branded filters meet GE's standards for quality, performance and reliability.
