Where Your Whirlpool Water Filter Sits and How to Access It

Most Whirlpool refrigerators have the water filter in one of three places: inside the fridge at the top right or left corner, in the base grille at the front bottom, or in the back upper right corner behind the fridge. Open your fridge door and look at the top corners first — if you see a cylindrical cartridge about the size of a soda can with a cap on top or bottom, that is your filter. If not, check the base grille by kneeling down and looking at the front panel near the floor. If neither location has it, you will need to pull the fridge away from the wall slightly and look at the back upper right area.

Write down your fridge model number before you start — it is on a sticker inside the fridge, usually on the side wall or top shelf. You will need this to order the correct replacement filter. Whirlpool filters are not universal across all their models, and using the wrong one can damage the water system or produce poor-tasting water.

Key Takeaways

  • Whirlpool water filters are located in three common spots: top corner inside the fridge, base grille at the front, or back upper right corner.
  • Your model number, found on a sticker inside the fridge, determines which replacement filter you need to order.
  • The replacement process takes about five minutes and requires only a quarter-turn or straight pull, depending on your filter type.
  • After installing the new filter, run water through the dispenser for 3 to 5 minutes to flush air and set up the filter.

Removing the Old Filter

Turn off the water supply to your fridge if your model has a shut-off valve — this is usually a small knob or lever on the water line behind the fridge. If you do not see one, you can proceed without shutting it off; you may get a small amount of water dripping, but it will not be a flood. Have a towel ready just in case.

If your filter has a cap on the bottom, grip the cap and turn it counterclockwise one quarter turn until it stops. The filter will drop into your hand. If your filter is in the base grille or has a straight pull design, grip the filter body and pull it straight toward you with steady pressure — it will slide out of the housing. Do not force it; if it is stuck, wiggle it gently side to side while pulling.

Water may drip from the housing or the old filter. Place your towel underneath and let it drain for a few seconds. If water continues to flow from the housing, turn off the water supply valve behind the fridge.

Installing the New Filter

Remove the new filter from its packaging and check that the rubber gaskets on both ends are clean and in place. If the filter came with a protective cap or plug, remove it now. Some filters have a blue or red indicator strip — this is normal and will fade as water runs through.

For a quarter-turn filter, align the filter with the housing opening and push it in until you feel resistance. Turn the cap clockwise one quarter turn until it stops and clicks. You should feel a firm stop; do not force it past that point. For a straight-pull filter, align the filter with the slot and push it straight in until it seats fully — you will feel it click or lock into place.

Turn the water supply back on if you shut it off. You may hear a brief hissing sound as air leaves the line; this is normal.

Flushing the New Filter

Go to your water or ice dispenser and run water for 3 to 5 minutes without stopping. The water may look cloudy or gray at first — this is air and carbon particles from the new filter. Keep running water until it runs clear. This step is important because it removes air from the system and activates the filter material.

If you have an ice maker, dispense 5 to 10 ice cubes and throw them away. The first batch of ice may taste off or look cloudy. After that, your water and ice should taste normal.

How Often to Replace the Filter

Whirlpool recommends replacing the filter every six months under normal use. If you have hard water, high sediment in your tap water, or use the dispenser heavily, you may need to replace it every three to four months. Some filters have a color-change indicator on the housing that darkens as the filter gets full — when it turns dark, it is time to replace it.

If your water pressure drops noticeably or the water tastes bad even after flushing, the filter may be clogged before six months have passed. Replace it early in that case. Keeping a spare filter on hand means you can swap it out without a trip to the store.

Finding the Right Replacement Filter

Whirlpool makes several filter types, and using the wrong one will not work. The most common models are the 4396508, 4396510, 4396511, and 4396547. Go to the Whirlpool website, enter your fridge model number in their parts finder, and order the filter listed for your model. You can also call Whirlpool customer service with your model number and they will tell you which filter you need.

Replacement filters cost between $30 and $60 depending on the model. You can order them from Whirlpool directly, Amazon, Lowe's, Home Depot, or local appliance parts stores. Buying in bulk or subscribing to automatic delivery through some retailers can lower the cost per filter.

Troubleshooting After Replacement

If water still tastes bad after flushing, the filter may not be seated correctly. Remove it and reinstall it, making sure you hear or feel it click into place. Run water again for another 3 to 5 minutes. If the taste persists, your tap water itself may have a problem unrelated to the filter — test it at a different faucet in your home.

If water pressure is very low or no water comes out, the filter may be installed backward or the housing may be blocked. Turn off the water, remove the filter, and look inside the housing for any debris or ice buildup. Wipe it clean with a damp cloth and reinstall the filter. If pressure is still low, the filter may be defective — contact Whirlpool or return it to the retailer.

Frequently Asked Questions

Do I have to turn off the water before replacing the filter?

No, but it is safer to do so. If you do not shut off the valve, you may get a small amount of water dripping from the housing. Have a towel ready. If water flows continuously, turn off the valve when ready.

What if I cannot find the water shut-off valve?

Check behind the fridge where the water line enters. If there is no valve there, look under the sink in the kitchen — sometimes the shut-off is at the main water line instead. If you still cannot find it, proceed with the replacement and keep a towel handy for drips.

Can I use a generic or off-brand filter instead of a Whirlpool filter?

Some third-party filters fit Whirlpool housings, but Whirlpool does not recommend them. Off-brand filters may not filter as well, could damage the water system, or may not fit correctly. Stick with the filter model your fridge requires.

Why does my water taste bad even after I flushed the new filter?

Run water for another 5 to 10 minutes — some filters need longer to fully set up. If the taste persists, the filter may not be seated correctly. Remove and reinstall it, making sure it clicks into place. If the problem continues, your tap water may have a separate issue.

How do I know when the filter is due for replacement?

Replace it every six months as a standard schedule. If your filter has a color-change indicator, replace it when the indicator darkens. If water pressure drops or taste worsens before six months, replace it early.
