The FPPWFU01 filter twists out and a new one twists in—no tools needed

The Frigidaire FPPWFU01 is a push-in cartridge filter that sits inside the water dispenser housing on the front of your refrigerator door or the back wall. To replace it, you turn the filter housing counterclockwise by hand until it stops, pull it straight out, and screw a new FPPWFU01 in until it seats firmly. The whole job takes about five minutes and requires no wrench or special equipment.

Before you start, turn off the water supply to your refrigerator. Most units have a shutoff valve under the sink or behind the fridge where the water line connects. If you cannot find it, you can proceed without shutting off the water—you will just have some spillage when you remove the old filter. Have a towel or small bucket ready either way.

Key Takeaways

  • The FPPWFU01 filter housing is located inside your refrigerator door or on the back wall, and you access it by turning the cartridge counterclockwise by hand.
  • Turning off the water supply before removal prevents water from leaking onto your floor, though the job can be done without it if you have a towel ready.
  • A new FPPWFU01 screws in clockwise until it stops—do not force it, and do not overtighten, or you will crack the housing.
  • After installation, run water through the dispenser for 30 seconds to flush air from the line and remove any carbon dust from the new filter.

Locating and accessing the filter housing

On most Frigidaire models, the FPPWFU01 housing is mounted inside the refrigerator door, usually in the upper corner on the left or right side. Open the door and look for a cylindrical cartridge about 4 inches tall with a knurled (ridged) grip around the middle. Some models mount the housing on the back wall of the fridge instead—check your manual if you cannot find it in the door.

Once you locate it, place a towel or shallow pan underneath to catch any water that drips when you remove the old filter. Even with the water supply shut off, there is usually a small amount of water trapped in the housing and the line.

Removing the old filter

Grip the filter housing firmly with your hand and turn it counterclockwise. You should feel resistance at first, then the cartridge will loosen. Keep turning until it stops—do not force it past that point. The housing will come free in your hand.

Pull the cartridge straight out and away from the refrigerator. Water will drip from the connection point, so keep your towel underneath. Discard the old filter in the trash—do not try to refill or clean it.

Look at the connection point where the filter was seated. You should see a small rubber O-ring or gasket. If it is still attached to the housing, leave it there. If it came out with the old filter, set it aside—you will need it for the new filter.

Installing the new FPPWFU01 filter

Before you insert the new filter, check that the rubber gasket is in place on the housing connection point. If it is not there, take the gasket from the old filter (if it came out) and press it firmly into the groove on the housing. If you do not have a gasket, the new filter may come with one—check the packaging.

Hold the new FPPWFU01 filter straight and align it with the housing opening. Push it in gently until you feel it seat, then turn it clockwise by hand. You will feel it tighten as the threads engage. Stop turning when you feel firm resistance—this usually happens after a quarter to half turn. Do not crank it hard or you will crack the plastic housing.

The filter should be snug but not so tight that you cannot turn it by hand if you need to remove it later. If you have to use a wrench or pliers to tighten it, you have gone too far.

Flushing the system and checking for leaks

Turn the water supply back on at the shutoff valve. Wait a few seconds for water to reach the filter, then press the water dispenser button and let water run for about 30 seconds. This flushes air out of the line and removes loose carbon dust from the new filter. The water may look slightly gray or cloudy during this time—that is normal and will clear after a few seconds.

While the water is running, watch the connection point where the filter screws into the housing. If you see water dripping or spraying, turn off the water when ready. The gasket may not be seated correctly, or the filter may not be tight enough. Remove the filter, check that the gasket is in the groove, and reinstall the filter, making sure it is snug.

What to do if the filter will not come out

If the housing is stuck and will not turn, do not force it—you can crack the plastic. Try wrapping a rubber band or rubber glove around the knurled grip to improve your grip, then turn slowly and steadily. If that does not work, let the filter sit for a few hours. Sometimes mineral deposits or corrosion can cause the threads to stick, and waiting allows them to loosen slightly.

If the filter still will not budge after waiting, you may need to replace the entire housing assembly. This is a job for a service technician, because it involves disconnecting the water line and may require tools specific to your model.

How often to replace the FPPWFU01

Frigidaire recommends replacing the FPPWFU01 every six months under normal use, or sooner if your water is hard or heavily chlorinated. If your water dispenser slows down, the water tastes or smells off, or the filter looks visibly discolored, replace it when ready—do not wait for the six-month mark.

Some refrigerators have a filter indicator light on the control panel. If yours does, the light will turn on when the filter is due for replacement. Reset the indicator after you install the new filter by holding the reset button (usually on the control panel or inside the fridge) for three to five seconds.

Frequently Asked Questions

Can I use a different brand of filter instead of the FPPWFU01?

You can use a compatible third-party filter if it is designed for the FPPWFU01 housing, but Frigidaire filters are engineered for your specific model and will fit and perform correctly. Off-brand filters may not seal properly or may have different filtration ratings. Stick with the FPPWFU01 or an equivalent Frigidaire replacement.

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

Turn off the water supply, remove the filter, and check that the rubber gasket is seated in the groove on the housing. Reinstall the filter and make sure it is snug but not over-tightened. If leaking continues, the gasket may be damaged and need replacement, or the housing threads may be stripped—contact a service technician.

Do I need to turn off the water supply before replacing the filter?

Turning off the water supply prevents spillage and makes the job cleaner, but it is not required. If you do not shut off the water, have a towel ready and work quickly. Water will drip from the connection point when you remove the old filter.

How do I reset the filter indicator light?

After installing the new filter, locate the reset button on your refrigerator's control panel or inside the fridge near the filter housing. Press and hold it for three to five seconds until the light turns off or the display resets. Consult your manual if you cannot find the reset button—the location varies by model.

Can I clean and reuse the old FPPWFU01 filter?

No. The FPPWFU01 is a disposable cartridge and cannot be cleaned or refilled. Once it is saturated with contaminants, it loses its filtration ability and should be discarded. Reusing a spent filter will not improve your water quality and may allow contaminants to pass through.
