Where the filter is and what you need before you start

The water filter in a KitchenAid French door refrigerator sits inside the refrigerator compartment, usually in the upper right corner behind the crisper drawers or in the grille at the bottom front of the unit. The exact location depends on your model year, but you can find it by looking for a cylindrical cartridge about the size of a soda can. Before you begin, locate your model number on the sticker inside the fridge or on the back wall—it starts with "KFXS" or similar—so you can order the correct replacement filter.

You will need the replacement filter (KitchenAid part number WFCB or WFIL, depending on your model), a bowl or cup to catch water, and a towel. The whole job takes about five minutes. Do not turn off the refrigerator or ice maker beforehand—you do not need to.

Key Takeaways

  • The water filter cartridge is located either in the upper right corner of the fridge compartment or in the bottom front grille, depending on your model year.
  • You can change the filter without turning off the refrigerator, and the process takes about five minutes with no tools required.
  • After installing the new filter, run water through the dispenser for 30 seconds to flush air and debris from the line.
  • KitchenAid filters should be replaced every six months or when water pressure drops noticeably, whichever comes first.

Removing the old filter from the upper right location

If your filter is in the upper right corner of the refrigerator compartment, move the crisper drawers out of the way to access it. You will see a cylindrical cartridge with a plastic cap on one end. Grip the cartridge firmly and turn it counterclockwise about a quarter turn—it will loosen and you can pull it straight out toward you. Water may drip, so position your bowl underneath.

Once the old filter is out, look at the opening where it came from. You will see a small rubber seal or O-ring. Wipe this area clean with a dry cloth to remove any debris or mineral buildup. This step prevents leaks when you install the new filter.

Removing the old filter from the bottom front grille

If your model has the filter in the bottom front grille, you may need to remove a decorative panel or access cover first. Check your owner's manual for your specific model, as some grilles slide out and others are held by a single screw. Once you can see the filter cartridge, turn it counterclockwise about a quarter turn and pull it straight out. Again, have your bowl ready for drips.

Wipe the rubber seal inside the housing clean before you install the new filter. If you see mineral deposits or discoloration around the seal, use a slightly damp cloth to clean it, then dry it completely.

Installing the new filter

Remove the new filter from its packaging and check that the rubber O-ring or seal on the end is in place and not damaged. If it looks dry or cracked, do not use it—contact KitchenAid for a replacement. Align the filter cartridge with the opening and push it in straight, then turn it clockwise until it stops. You will feel it seat firmly; do not force it past that point.

The filter should be snug but not so tight that you cannot remove it by hand later. If you have to use pliers or a wrench, you have turned it too far. Back it off slightly until it feels find but hand-removable.

Flushing the line and checking for leaks

After the new filter is installed, go to the water dispenser on the door and run water for about 30 seconds into a sink or large bowl. This flushes air and loose carbon particles from the new filter and the water line. The water may look slightly cloudy or taste a bit off for the first few gallons—this is normal and will clear.

While the water is running, check underneath the filter location inside the fridge for any drips. If water is leaking from where the filter meets the housing, turn off the water dispenser, remove the filter, and check that the O-ring is seated correctly. Reinstall it and test again. If leaking continues, the O-ring may be damaged and you may need to order a replacement seal kit from KitchenAid.

When to replace your filter and what to watch for

KitchenAid recommends replacing the water filter every six months under normal household use. If you have hard water or high sediment in your supply, you may need to replace it more often. The first sign that a filter needs changing is a drop in water pressure at the dispenser—the water will come out slower than usual. A second sign is a change in taste or odor, which means the filter is saturated and no longer removing contaminants effectively.

Some KitchenAid models have a filter status light on the control panel that will turn red or amber when the filter is due for replacement. Check your owner's manual to see if your model has this feature. Even if the light has not come on, if you notice reduced pressure or taste changes, go ahead and change the filter—it is inexpensive insurance against drinking water that is no longer being filtered properly.

Ordering the correct replacement filter for your model

KitchenAid uses two main filter types: the WFCB (side-by-side and some French door models) and the WFIL (newer French door models). The easiest way to find the right one is to look at your model number on the refrigerator itself or in your owner's manual, then search that number on the KitchenAid parts website. You can also call KitchenAid customer service with your model number and they will tell you which filter you need.

Replacement filters are sold at most appliance retailers, online marketplaces, and directly from KitchenAid. Prices vary but typically range from $30 to $60 per filter. Some retailers sell multi-packs at a discount if you want to keep a spare on hand. Store the spare filter in a cool, dry place—do not open the packaging until you are ready to use it.

Frequently Asked Questions

Do I need to turn off the refrigerator before changing the filter?

No. You can change the filter while the refrigerator is running. The water line has a shutoff valve inside the filter housing itself, so turning off the main power is not necessary. Just have a bowl ready to catch any water that drips when you remove the old filter.

What if water is leaking from the filter after I install it?

Check that the filter is turned clockwise as far as it will go without forcing it. If it is tight and still leaking, remove it and inspect the rubber O-ring for cracks or damage. If the O-ring looks intact, wipe both the O-ring and the housing opening clean and reinstall. If leaking continues, the O-ring may be defective and you should contact KitchenAid for a replacement seal.

Can I use a third-party or generic filter instead of a KitchenAid filter?

Third-party filters may fit physically, but KitchenAid does not warrant them and they may not filter water to the same standard. Using a non-approved filter can also void your refrigerator warranty. Stick with KitchenAid part numbers WFCB or WFIL to may support proper fit and performance.

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

Cloudiness after a new filter installation is normal and caused by air trapped in the filter and water line. Run water from the dispenser for 30 to 60 seconds and the cloudiness will clear. If it persists after a few minutes, check that the filter is installed correctly and seated fully.

How do I know which filter location my model has?

Check your owner's manual or look at your model number on the KitchenAid website. You can also open the refrigerator and look in the upper right corner first—if you do not see a filter there, check the bottom front grille. Your model number will always tell you which type, so when you order a replacement, the part number will match your configuration.
