How to Replace a KitchenAid Refrigerator Water Filter

You use your KitchenAid refrigerator every day, but when was the last time you thought about its water filter? If your water or ice tastes funny, or your fridge is flashing that dreaded “Replace Filter” light, don’t worry—you’re not alone. Changing your refrigerator’s water filter might seem tricky, but it’s actually one of the easiest things you can do to keep your water clean and tasting great. In this article, we’ll walk you through everything you need to know, step-by-step, even if you’ve never done it before.

What Kind of Water Filter Does My KitchenAid Refrigerator Use?

Before you can change the filter, you need to know exactly what kind of filter your refrigerator uses. Not all filters are created equal. KitchenAid refrigerators typically use one of a few common types, and using the wrong one could mean unfiltered water or even damage to your appliance.

How to Identify Your Filter Model

The first thing you want to do is locate your current water filter. Most KitchenAid refrigerators have the filter located in one of three common places: in the upper right corner inside the fridge, behind the base grille at the bottom, or inside a compartment near the back panel.

If you’re not sure where yours is, check your owner’s manual. If that’s long gone, no worries—look inside the fridge and behind the kick plate at the bottom. It’s usually easy to spot.

Once you find the filter, remove it and look for the model number. Most filters will have a label printed directly on them that includes the part number. For example, you might see numbers like “EDR1RXD1,” “EDR2RXD1,” or “EDR3RXD1.” These are the EveryDrop filter numbers, which are commonly used in KitchenAid fridges.

Write this number down or take a photo with your phone. This is the number you’ll use when buying a replacement.

Understanding EveryDrop Filter Types

KitchenAid recommends EveryDrop filters, and each number corresponds to a specific filter shape and connection type. Here are the most common ones:

Filter 1 (EDR1RXD1): Found in the upper right inside the fridge
Filter 2 (EDR2RXD1): Typically found in the top back panel
Filter 3 (EDR3RXD1): Installed through the front base grille
Filter 4 (EDR4RXD1): Used in certain French door models
Filter 5 (EDR5RXD1): Common in older models

Using the correct filter type is essential because a mismatch might prevent it from locking in place or functioning properly.

Where to Buy Replacement Filters

Once you know your filter type, you can purchase a replacement. KitchenAid recommends buying authentic EveryDrop filters. These are available directly from the KitchenAid website, online retailers like Amazon, or big-box stores like Home Depot, Lowe’s, or Walmart.

If you choose to buy from a third-party brand, make sure it is NSF-certified and compatible with your model. This ensures that the filter actually removes contaminants and won’t damage your appliance.

Signs It’s Time to Replace the Filter

Even if your refrigerator doesn’t alert you, there are clear signs your filter may need changing:

Water or ice tastes or smells odd
Water pressure has decreased
The water is cloudy
You see black specks in water (carbon particles from the filter)
It’s been more than 6 months since your last change

Your filter does a lot of heavy lifting behind the scenes. Replacing it regularly keeps your water clean and fresh.

How Do I Remove the Old KitchenAid Water Filter?

Now that you’ve got the right replacement, it’s time to take the old filter out. But how you remove the filter depends on where it’s located and the type of filter housing your fridge uses. Don’t worry—we’ll break it down step-by-step.

Filter in the Upper Right Corner (Push-Button Style)

Many newer KitchenAid models have the filter in the upper right-hand corner inside the fridge.

Open your refrigerator door fully to access the top right area.
Locate the filter door. You’ll usually see a plastic cover.
Push the eject button or gently pull open the cover door. This will cause the filter to pop out slightly.
Once it has popped out, grab it and pull straight out. If it resists, wiggle gently while pulling.

Be careful not to use too much force—if it doesn’t come out easily, make sure the cover is fully open and you’re pulling straight.

Base Grille Filter (Twist-and-Pull Style)

Some older KitchenAid models have the filter located behind the base grille at the bottom front of the fridge.

Bend down and find the round or oval cap sticking out from the grille.
Grab the filter cap and twist it counterclockwise about a quarter-turn. This will release the filter.
Once it unlocks, pull it straight out from the slot.
If the cap stays on the filter, gently remove it and save it to use with the new one.

These filters are often tight, so don’t be afraid to use a bit of muscle if needed. Just avoid twisting too hard, or you could break the cap.

Inside Back Panel Filters (Flip-Open Housing)

Some French door KitchenAid models have filters located inside the fridge near the top back panel, usually behind a flip-up housing.

Open the fridge doors wide to access the filter area.
Look for a flip-up plastic housing with a small lip or tab.
Lift the housing up until it locks open.
The filter should be sitting horizontally. Pull it straight out.

These models are designed for easy access, so the filter should slide out without much resistance.

How Do I Install a New Water Filter in My KitchenAid Refrigerator?

You’ve removed the old filter—great job! Now it’s time to install the new one. The process is pretty straightforward, but you want to be sure it clicks or locks in correctly to avoid leaks or improper filtration.

Installing a Push-In Filter in the Top Right Corner

If your refrigerator has the filter slot in the upper right-hand corner:

Unpack your new filter and remove any plastic caps or stickers.
Align the notches on the end of the filter with the grooves in the slot.
Push the filter straight in until it clicks or locks into place.
Close the cover door over the filter.

Sometimes you may need to apply a bit of pressure to get the click. Make sure it feels secure and doesn’t wiggle.

Installing a Twist-In Filter in the Base Grille

If your old filter was in the base grille and had a twist mechanism:

If your new filter doesn’t have a cap, take the cap from your old filter and twist it onto the new one.
Align the filter with the slot in the grille and push it in.
Twist it clockwise until it locks into place—usually about a quarter-turn.
Make sure the cap is horizontal when done.

It’s important to make sure the filter is fully locked in. If it sticks out or feels loose, take it out and try again.

Installing a Flip-Top Filter in the Back Panel

If your fridge has a flip-up housing at the top:

Remove the protective cover from the new filter.
Insert the new filter horizontally into the slot with the correct orientation.
Push it all the way in until it clicks.
Close the flip-up housing cover until it snaps shut.

This style of filter is very user-friendly, and you’ll know you’ve done it right when the filter feels secure and the cover closes easily.

What Should I Do After Installing the New Filter?

You’re not quite done yet—there are a few important steps to follow after installing the new filter. This final phase ensures your water tastes fresh and your fridge functions properly.

Resetting the “Replace Filter” Light

Most KitchenAid refrigerators have a “Replace Filter” or “Order Filter” indicator light. After installing the new filter, you’ll want to reset it.

Locate the reset button. It’s often near the light, on the control panel, or in your settings menu.
Hold down the reset or “Max Ice/Water” button for 3–5 seconds.
Wait for the indicator light to turn off or return to normal.

If your model doesn’t have a reset button, consult your owner’s manual for the correct reset procedure.

Flushing the New Filter

Even new filters can have air bubbles or loose carbon particles inside. You’ll want to flush out a few gallons of water before drinking.

Grab a pitcher or container.
Dispense water through the fridge’s dispenser.
Let about 3 to 5 gallons of water run through. You can do this in short bursts if needed.
Dump the first few pitchers of water or use them to water plants—just don’t drink it.

Flushing the filter is important for removing any residue or air pockets that could affect taste or pressure.

Checking for Leaks

After everything’s installed, inspect the area around the filter.

Use a dry cloth or paper towel to wipe around the filter housing.
Check for drips or puddles under the fridge after an hour.
If you see any leaks, remove and reinstall the filter. It may not be seated properly.

Leaks are rare when the filter is installed correctly, but it’s always a good idea to double-check.

Making a Note for Your Next Filter Change

Most refrigerator filters need replacing every 6 months. To stay ahead of it:

Set a calendar reminder on your phone
Write the date on the filter with a marker
Use a sticker or magnet on the fridge

Staying on top of your filter changes keeps your water clean and your appliance running smoothly. I hope this guide made replacing your KitchenAid refrigerator water filter easy and stress-free.

Frequently Asked Questions (FAQs)

Is it necessary to flush a new refrigerator water filter?

Yes, it’s definitely necessary. When a new filter is manufactured, it can have tiny carbon dust particles or trapped air inside. These can affect both the taste and appearance of your water if not flushed out properly. Flushing the filter clears out this residue and ensures that the water you’re drinking is clean and fresh. Most manufacturers, including KitchenAid, recommend flushing 3 to 5 gallons of water through the dispenser after installing a new filter. Skipping this step can also cause sputtering or unusual sounds as air bubbles pass through your water lines. It might even reduce your water pressure temporarily. So while it might feel like a waste, flushing ensures you’re getting the best performance from your filter and the safest, best-tasting water.

Can I use my refrigerator without a water filter installed?

You can, but it depends on the model. Some KitchenAid refrigerators have a built-in bypass system that allows the water to flow even without a filter. In these cases, you can insert a filter bypass plug, which you may have received when you first bought the fridge. This plug lets water bypass the filter chamber entirely. However, keep in mind that you’ll be drinking and using unfiltered water, which may contain chlorine, sediment, or even contaminants depending on your local supply. If your fridge doesn’t have a bypass plug or system, removing the filter may stop water and ice production altogether. It’s best to check your manual or call KitchenAid support before trying to run the fridge without a filter.

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

In most KitchenAid refrigerators, no—there’s no need to turn off the water supply before changing the filter. The design includes a built-in shut-off valve that stops water flow when you remove the filter. This makes it safe and easy to change without worrying about leaks or spills. That said, it’s always a good idea to place a towel underneath the filter area, just in case a few drops of water escape during the swap. If your fridge is older or has been modified, you may want to consult your manual to be sure. In rare cases where the valve doesn’t shut off properly or the filter area is damaged, turning off the water at the main supply can be a smart precaution.

Is it okay to use generic or off-brand water filters?

Yes, it’s okay, but you need to be cautious. Not all off-brand or generic filters are created equal. Some may be cheaply made and not properly tested for safety or filtration effectiveness. If you choose to go with a generic brand, make sure the filter is NSF-certified, which means it’s been tested and meets certain standards for removing contaminants. Also, verify that the filter is compatible with your specific KitchenAid model. Using a poorly fitting or untested filter can result in leaks, bad taste, or even damage to your fridge’s water system. Many people prefer sticking with OEM (Original Equipment Manufacturer) filters like EveryDrop to avoid these issues, but reputable third-party options do exist.

Is it normal for water to sputter after installing a new filter?

Yes, it’s completely normal. When you install a new filter, there is often some trapped air inside the cartridge or the water lines. This air gets pushed out when you first use the dispenser, and it can cause the water to sputter or spurt in an uneven stream. It might also make gurgling or hissing noises as the air escapes. This usually goes away after you dispense a few cups or a couple of gallons of water. Flushing the system, as recommended, will help clear the air more quickly and restore a steady stream. If sputtering continues for more than a day or two, double-check that the filter is installed correctly and seated all the way in.

Can I recycle my old refrigerator water filter?

Some parts of water filters can be recycled, but not through your regular curbside program. Many manufacturers, including EveryDrop, offer special recycling programs that allow you to mail in used filters. These programs make sure the plastic, carbon, and internal components are handled properly. To recycle, check the packaging of your new filter for instructions or visit the manufacturer’s website. If your filter doesn’t come with a recycling option, you can try asking local hardware or appliance stores if they participate in recycling programs. Never throw used filters in the regular trash if you can help it, as they contain materials that are better disposed of or reused responsibly.

Do I need a professional to change my water filter?

No, you definitely don’t need a professional. Changing the water filter in your KitchenAid refrigerator is designed to be a simple, do-it-yourself task. The process usually takes just a few minutes and doesn’t require any tools. With clear instructions and the right replacement filter, even someone who’s never worked with appliances can do it with ease. That said, if you’re ever unsure or something feels off—like the filter won’t click in place, or the water dispenser stops working—it’s okay to call KitchenAid support or even a technician. But for most people, doing it yourself saves time, money, and gives you peace of mind.

Is it bad to go too long without changing the water filter?

Yes, it can be. Water filters become less effective over time as they trap more and more contaminants. After about six months, most filters are saturated and can’t filter properly anymore. This means your drinking water might start to taste bad or even become unsafe. You may also notice a drop in water pressure or odd smells coming from your ice. In some cases, bacteria can even start to grow inside an old filter. That’s why it’s recommended to replace your refrigerator water filter every six months—even if the water still seems fine. Regular changes keep your water clean and your fridge working efficiently.
