How To Replace A Filter In A Whirlpool Refrigerator

ByJim Boslice Home & Kitchen

To replace your Whirlpool refrigerator filter, locate the housing in the upper right corner or the bottom grille, remove the old filter by twisting or pushing the release button, and slide in the new EveryDrop filter until it clicks. Always flush 3-4 gallons of water through the new filter to remove air and carbon fines before drinking.

Clean, crisp water is one of those modern conveniences we often take for granted until that “replace filter” light starts glowing red on the dispenser. If you are like most DIYers, you probably hate the idea of paying a service technician a hundred dollars for a job that takes less than five minutes.

I promise that learning how to replace a filter in a whirlpool refrigerator is one of the easiest maintenance tasks you can perform in your home. You do not need a toolbox full of specialized equipment or a degree in mechanical engineering to get this done correctly and safely.

In this guide, we are going to walk through the different types of Whirlpool filtration systems, the specific steps for each mounting style, and how to troubleshoot those stubborn filters that just won’t budge. Let’s get that water tasting fresh again and keep your appliance running at peak performance.

Understanding Your Specific Whirlpool Filter System

Before you start pulling on plastic covers, you need to know what you are looking at. Whirlpool has standardized most of their modern units to use the EveryDrop line of filters, but older models might still use legacy part numbers. Knowing your model number is the first step in any successful DIY repair.

Whirlpool typically places the filter in one of two locations: the upper right-hand corner of the interior or behind a small door on the bottom base grille. The location of the filter usually dictates the locking mechanism used to hold it in place.

Most modern side-by-side and French door models utilize a numbered system (Filter 1 through Filter 5). Each number corresponds to a specific shape and connection point, so they are not interchangeable. Check your owner’s manual or the label on the old filter before buying a replacement.

The Interior Top-Right Filter

If your filter is located inside the fridge, it is likely tucked away in the top right corner. These units usually have a flip-down door. When you open the door, the filter is exposed, and it often uses a push-to-release or a quarter-turn twist mechanism to disengage from the manifold.

These filters are generally the easiest to access because you do not have to crawl on the floor. However, they can occasionally leak a few drops of water when removed, so having a shop rag handy is a smart move for any careful homeowner.

The Bottom Base Grille Filter

On many older side-by-side models, the filter is located at the very bottom of the unit. You will see a circular plastic cap sticking out from the grille. These filters usually require you to push a button located right next to the cap to eject the cartridge.

Because these are close to the floor, they can collect dust and pet hair. It is a good idea to vacuum the grille while you are down there to improve the airflow to your refrigerator’s condenser coils, killing two birds with one stone.

Essential Tools and Materials for the Job

One of the best things about learning how to replace a filter in a whirlpool refrigerator is that the tool list is incredibly short. In most cases, your bare hands are all you need. However, having a few “just in case” items nearby will prevent a trip back to the garage mid-project.

  • New Replacement Filter: Ensure it is an OEM (Original Equipment Manufacturer) EveryDrop filter or a high-quality certified NSF-rated alternative.
  • A Clean Towel: To catch the small amount of “residual water” that escapes when the seal is broken.
  • A Large Pitcher: You will need this to flush the system after the installation is complete.
  • Pliers (Optional): Sometimes the bottom-grille filters get stuck due to mineral buildup, and a pair of slip-joint pliers can provide extra leverage.

Using a genuine filter is highly recommended. While “knock-off” filters are cheaper, they often lack the same level of contaminant reduction and can sometimes have fitment issues that lead to slow leaks inside your cabinetry.

Mastering how to replace a filter in a whirlpool refrigerator Step-by-Step

Now that you have your supplies and have located the housing, it is time to perform the swap. We will break this down by the two most common mounting styles found in Whirlpool refrigerators today. Follow these steps closely to ensure a watertight seal.

Style 1: The Interior Flip-Down Door

First, locate the filter cover in the upper right corner of the refrigerator interior. You will see a small notch or a button that allows the cover to swing downward. Once the door is open, you will see the end of the filter cartridge.

  1. Remove the Old Filter: Depending on your specific model, you will either twist the filter counter-clockwise a quarter turn or simply push the filter inward to trigger the spring-release mechanism.
  2. Prepare the New Filter: Remove the plastic wrap and the protective caps from the O-rings. It is a pro-tip to moisten the O-rings with a tiny bit of water to help them slide into the manifold without tearing.
  3. Insert the New Filter: Align the filter with the grooves in the housing. Push it in firmly or twist it clockwise until it stops. You should feel a distinct “click” or tactile feedback when it locks into place.
  4. Close the Cover: Swing the door back up until it snaps shut. If the door won’t close, the filter isn’t seated all the way back.

Style 2: The Bottom Grille Push-Button

For filters located at the bottom of the fridge, look for the release button next to the filter cap. This style is common in older side-by-side configurations. It is slightly more prone to sticking, so be patient with the mechanism.

  1. Eject the Filter: Press the button firmly. The filter should pop out about an inch. Pull the cartridge straight out of the housing.
  2. Transfer the Cap: The plastic cap on the end of the filter is usually a reusable decorative piece. Twist it off the old filter and slide it onto the new one.
  3. Install the New Unit: Slide the new filter into the hole with the cap aligned correctly. Push it in until the eject button pops back out, indicating the filter is locked.
  4. Check Alignment: Ensure the cap is flush with the grille so it doesn’t get kicked or caught on a vacuum cleaner later.

Why Flushing the System is Non-Negotiable

Once the new filter is in, you aren’t quite finished. A critical part of knowing how to replace a filter in a whirlpool refrigerator is understanding the “flushing process.” New carbon filters contain loose “carbon fines” (dust) and trapped air from the manufacturing process.

If you skip this step, your first few glasses of water will likely be cloudy, gray, or filled with tiny black specks. While these carbon particles aren’t harmful, they don’t taste great and can cause the water dispenser to sputter and spray water all over your kitchen floor.

Place a large pitcher under the dispenser and hold the trigger. It may take a few seconds for the water to start flowing as the filter housing fills up. Run approximately 3 to 4 gallons of water through the system. This clears the lines and ensures the water you drink is as pure as the filter intends.

During this process, you might hear some loud “thumping” or “hissing” sounds. Don’t panic; that is just air being purged from the internal water lines. Once the stream is steady and clear, you are ready to go.

Troubleshooting Common Filter Issues

Sometimes, things don’t go exactly as planned. Even when you know how to replace a filter in a whirlpool refrigerator, mechanical parts can be stubborn. Here are the most common “hiccups” DIYers face and how to fix them without calling a repairman.

The Filter is Stuck and Won’t Turn

In areas with hard water, calcium and mineral deposits can build up around the filter housing seal. If the filter won’t twist, try using a dry cloth to get a better grip. If it still won’t move, you can use a pair of pliers, but be extremely gentle.

Plastic housings can crack under too much pressure. Sometimes, turning the refrigerator’s water supply valve off briefly to relieve the internal water pressure can make the filter easier to rotate. Once the pressure is gone, the locking lugs often release much more smoothly.

The Water Flow is Extremely Slow

If you install a new filter and the water barely trickles out, you might have a “lemon” filter or an air lock. Try removing the filter and reinstalling it to ensure the O-rings are seated perfectly. If the flow is still slow, check that the refrigerator’s water supply valve (usually behind the unit) is fully open.

Occasionally, the internal bypass valve in the filter head can fail. If you put the old filter back in and the flow returns to normal, then the new filter is likely defective or the wrong model for your specific manifold.

How to Reset the Filter Indicator Light

Even after you successfully finish how to replace a filter in a whirlpool refrigerator, that pesky red light will usually stay on. The refrigerator doesn’t actually “sense” the new filter; it just works on a timer or a gallon counter.

You have to manually tell the computer that you’ve done the maintenance. The reset procedure varies depending on your control panel style, but here are the most common methods:

  • The Filter Button: Press and hold the “Filter Reset” button for 3 seconds until the light turns blue or green.
  • The Light and Ice Buttons: On some models, you must press and hold “Light” and “Ice Type” (or “Filter”) simultaneously for 3 seconds.
  • The Options Menu: For touch-screen models, navigate to “Options,” then “Filter Reset,” and follow the on-screen prompts to confirm the change.

If the light doesn’t reset on the first try, wait a minute and try again. Sometimes the control board needs a moment to register the long-press. Once the light is reset, you are officially done for the next six months.

Frequently Asked Questions About how to replace a filter in a whirlpool refrigerator

How often should I really change my Whirlpool filter?

Whirlpool recommends changing the filter every six months or every 200–300 gallons. However, if you have a large family or live in an area with high sediment in the water, you might need to change it sooner if you notice a drop in water pressure.

Can I run my refrigerator without a filter?

Yes, most Whirlpool models come with a filter bypass plug or have a built-in bypass mechanism. If you remove the filter and don’t replace it, the water will still flow, but it won’t be filtered. This is useful if you have a whole-house filtration system already in place.

What happens if I don’t change the filter?

Over time, the activated carbon inside the filter becomes saturated and can no longer trap contaminants. Furthermore, old filters can become a breeding ground for bacteria and may eventually clog completely, stopping the flow of water to your dispenser and ice maker.

Why is my new water filter making a loud noise?

Loud noises usually indicate trapped air in the lines. This is common immediately after installation. Running a few gallons of water through the dispenser should purge the air and silence the system. If the noise persists, check for a secure connection.

Final Thoughts for the DIY Homeowner

Mastering how to replace a filter in a whirlpool refrigerator is a fundamental skill for maintaining a healthy and efficient home. It is a simple task that saves you money, reduces plastic waste from bottled water, and ensures your family has access to clean, safe hydration.

Remember to always double-check your model number, use a towel to catch those stray drops, and never skip the flushing process. These small details are what separate a “hack job” from a professional-grade DIY repair.

Now that you’ve tackled the fridge, take a look around your workshop or kitchen—what other small maintenance tasks have you been putting off? With the right mindset and a little bit of guidance, there is almost nothing in your home you can’t handle yourself. Happy tinkering!
