Where Your GE Water Filter Is Located

Most GE refrigerators have the water filter in one of two places: inside the refrigerator compartment (usually in the upper right corner or along the back wall) or underneath the sink in the cabinet below. Check your refrigerator's door or the wall inside the fridge first—if you see a cylindrical cartridge about the size of a soda can with a blue or white plastic housing, that is your filter. If you do not see it there, look under the sink where the water line connects to your refrigerator.

The filter cartridge itself is what you replace, not the entire housing. The housing stays in place and screws into your water supply line. Inside that housing sits the replaceable filter, which is what traps sediment and odors from your water.

Key Takeaways

  • Turn off the water supply to your refrigerator before you start, or shut off the main water valve if you cannot find the refrigerator shutoff.
  • The filter cartridge twists counterclockwise by hand—you do not need tools, and forcing it will crack the plastic housing.
  • Write down your filter model number (it is printed on the old cartridge) before you buy a replacement, because GE makes different sizes for different models.
  • After installing the new filter, run water through the dispenser for 30 seconds to flush air from the line and remove any carbon dust from the new filter.
  • Most GE filters last 6 months or 300 gallons, whichever comes first, though some models are rated for 12 months.

Turn Off the Water Supply

Locate the water shutoff valve for your refrigerator. This is usually a small valve on the water line behind or underneath the refrigerator, or in the cabinet under the sink where the line enters your home. Turn the valve clockwise until it stops—you should feel resistance, but do not force it. If you cannot find a dedicated shutoff for the refrigerator, turn off the main water valve for your house instead.

Open your refrigerator's water dispenser and let water run for 5 to 10 seconds. This releases pressure in the line and prevents water from spraying when you unscrew the filter. If no water comes out, the shutoff is working correctly.

Remove the Old Filter Cartridge

Grip the filter cartridge firmly with one hand and turn it counterclockwise. The cartridge should rotate smoothly—if it is stuck, wrap a dry cloth around it for better grip, but do not use pliers or a wrench. Most cartridges unscrew by hand in 2 to 3 full rotations. Once it is loose enough, pull it straight out of the housing.

Water may drip from the housing or the cartridge itself. Have a small bowl or towel ready to catch it. If water continues to drip after you have removed the cartridge, that is normal—the line is still pressurized slightly. Let it drain into the bowl for a few seconds.

Find Your Replacement Filter Model Number

Look at the old cartridge you just removed. The model number is printed on the plastic housing or on a label wrapped around the cartridge. It usually starts with "GSWF" or "MSWF" and is followed by numbers. Write this number down or take a photo of it before you throw the old filter away.

GE makes different filter sizes for different refrigerator models. Buying the wrong size will not fit into your housing. You can order the correct replacement online using the model number, or take the old cartridge to an appliance parts store and ask for the matching replacement. Common GE models include GSWF, MSWF, and GXRTDR, but your refrigerator may use a different one.

Install the New Filter Cartridge

Remove the new cartridge from its packaging. Some filters come with a protective cap on the inlet end—remove this cap before installation. Align the cartridge with the opening in the housing and push it straight in until you feel it seat against the housing. Then turn it clockwise by hand until it stops. You should feel a slight resistance when it is fully tightened, but do not over-tighten—a quarter turn past snug is enough.

Do not use tools to tighten the cartridge. Hand-tight is correct. Over-tightening can crack the plastic housing and cause leaks.

Turn the Water Back On and Flush the Line

Turn the shutoff valve counterclockwise to restore water pressure. Turn it slowly so air does not get trapped in the line. You should hear water flowing into the refrigerator within a few seconds. If you do not hear anything after 30 seconds, check that the valve is fully open and that the cartridge is seated correctly in the housing.

Open the water dispenser and let water run for 30 seconds. The first water may be cloudy or taste slightly of carbon—this is normal and comes from the new filter material. After 30 seconds, the water should run clear. If water does not come out at all, turn off the valve again and check that the cartridge is pushed all the way into the housing and twisted clockwise until snug.

When to Replace Your Filter Again

Most GE water filters last 6 months or 300 gallons of water, whichever comes first. Some newer models are rated for 12 months. Check your refrigerator's manual or the cartridge packaging to find the rating for your specific filter. Mark the installation date on your calendar or on the filter housing itself with a permanent marker so you remember when to replace it.

If your water tastes bad, smells like chlorine, or the dispenser flow slows down before 6 months have passed, the filter may be clogged. Replace it early if this happens. Hard water or sediment-heavy tap water will clog a filter faster than soft water.

Frequently Asked Questions

What if water leaks from the filter housing after I install the new cartridge?

The cartridge is not seated correctly or is not twisted tight enough. Turn off the water, unscrew the cartridge, and push it straight into the housing until you hear or feel a click. Then twist it clockwise until snug—about a quarter turn past hand-tight. Do not force it. Reinstall and turn the water back on.

Can I use a third-party filter instead of a genuine GE cartridge?

Yes. Third-party filters made for your GE model number work the same way and cost less. Make sure the replacement is rated for your specific model number—GSWF, MSWF, or whatever your old cartridge says. Avoid generic filters that do not list a compatible model number.

Why is my water cloudy after I install a new filter?

New filter cartridges release fine carbon particles into the water during the first use. Run water through the dispenser for 30 to 60 seconds to flush these particles out. The water should clear after that. If it stays cloudy for more than a minute, turn off the water and check that the cartridge is installed correctly.

Do I need to reset anything on my refrigerator after changing the filter?

Some GE models have a filter status light on the control panel. If yours does, press and hold the reset button (usually labeled "Filter Reset" or "Reset") for 3 seconds after you install the new cartridge. Check your refrigerator's manual for the exact location and timing. Not all models have this feature.

What should I do with the old filter cartridge?

Most water filter cartridges can go in your regular trash. Some areas have recycling programs for plastic cartridges—check with your local waste management. Do not pour the old filter down the drain or try to clean and reuse it.
