How to Replace the Water Filter on a KitchenAid Refrigerator

KitchenAid refrigerators are built by Whirlpool and use the same EveryDrop filter platform as Whirlpool, Maytag, Amana, Jenn-Air, and Kenmore models made on the same platform. That is useful to know because it significantly expands the range of compatible replacement options available to you -- and it explains why the filter model number on your KitchenAid may show a Whirlpool part number or an EveryDrop designation rather than a KitchenAid-branded part.

This guide covers how to identify the right filter for your specific KitchenAid model, how to replace it regardless of installation style, how to reset the indicator light, and where to find OEM and compatible replacements at DFS.

Step 1 -- Identify the Right Filter for Your KitchenAid Refrigerator

KitchenAid refrigerators use several different EveryDrop filter models depending on the refrigerator series, configuration, and year of manufacture. The table below maps the most common KitchenAid filter types to their EveryDrop designation, location, and installation style.

The fastest way to confirm which filter your KitchenAid uses is to remove the existing filter and read the model number printed on the cartridge body. That number can be entered directly into the DFS search bar to pull up OEM and compatible replacement options immediately. If the filter is missing or the number is unreadable, the DFS Fridge Filter Finder identifies the correct filter by walking through refrigerator brand, style, and filter location. The full KitchenAid refrigerator filters collection is organized by filter model for direct browsing.

Step 2 -- Locate the Filter in Your Refrigerator

KitchenAid refrigerators install the filter in one of two general locations: inside the refrigerator compartment, or in the base grille at the bottom front of the unit.

Interior filters on French door and some side-by-side models are typically in the upper right corner of the fresh food compartment, or occasionally near the ceiling of the compartment on models using the EDR4RXD1. Base grille filters on most KitchenAid side-by-side models are behind a flip-down or push-release cover at the bottom front of the unit. Opening the filter cover before reaching for the cartridge is the step most often skipped -- the cover must be fully open before the filter will release.

Step 3 -- Replace the Filter

No tools are required for any current KitchenAid EveryDrop filter. Keep a small towel nearby as a few drops of water typically release when the old filter is removed.

For interior push-button or push-in filters: press the release button on the filter or housing, pull the cartridge straight out, remove packaging and protective caps from the new filter, slide it firmly into the housing until it clicks securely into place.

For interior twist-in filters: rotate the old filter a quarter-turn counterclockwise and pull it out, then push the new filter into the housing and rotate clockwise a quarter-turn until it locks.

For base grille quarter-turn filters (EDR3RXD1, EDR5RXD1, EDR6D1): press the button on the grille cover to open it, press the button on the filter itself and pull the old filter straight out, push the new filter firmly into the manifold slot until it stops, then push up firmly once more to confirm full engagement before closing the grille cover.

A correctly installed filter locks firmly with no wobble and allows immediate water flow from the dispenser. If the filter appears seated but no water flows, remove it and reseat with more deliberate pressure until the engagement locks.

Step 4 -- Flush the New Filter

Dispense 3 to 4 gallons of water from the refrigerator dispenser and discard it before drinking. New filters release harmless carbon fines and trapped air during initial use -- flushing clears both and ensures the first glass you drink is clean. Cloudiness and slight sputtering in the first several glasses are normal and clear quickly. This applies to the ice maker as well -- the first one or two ice batches after a filter change should be discarded.

Step 5 -- Reset the Filter Indicator

KitchenAid refrigerators require a manual reset after every filter change. The indicator does not detect a new cartridge automatically -- it runs on a timer that must be cleared after installation.

On most KitchenAid models: press and hold the Filter Reset or Water Filter button on the control panel for 3 to 5 seconds until the indicator changes from red or orange to green or turns off. On models without a dedicated filter reset button: press the door light switch (the small button that activates the interior light when the door opens) five times within 10 seconds -- this triggers the reset on many side-by-side models that use the base grille filter configuration. If neither method works, the reset option may be accessible through the Settings or Filter Status menu on models with touch screen displays.

Which Replacement Filter to Buy

DFS carries both OEM EveryDrop filters and certified compatible Tier1 and Tier1 Plus replacements for every current KitchenAid filter model.

For the most common KitchenAid side-by-side configuration using the EDR5RXD1 in the base grille, the Tier1 EDR5RXD1 replacement is certified to NSF/ANSI 42 and 372, rated for up to 400 gallons or 6 months, and uses a 5-micron coconut shell carbon block. For households that want lead and mercury reduction alongside chlorine and sediment performance, the Tier1 Plus EDR5RXD1 replacement adds NSF/ANSI 53 certification and a tighter 0.5-micron carbon block -- a meaningful upgrade for any household with lead or health contaminant concerns.

For KitchenAid models using the EDR4RXD1 interior or base-grille filter, the Tier1 Plus EDR4RXD1 replacement is certified to NSF 42, 53, and 401 -- covering chlorine, lead, pharmaceuticals, and emerging contaminants in a single cartridge. The OEM EveryDrop EDR4RXD1 Filter 4 is also available for households that prefer the manufacturer original.

For a broader comparison of OEM vs. compatible replacement options across the full EveryDrop lineup, the fridge filter buying guide covers NSF certifications, compatibility, and what each tier of filtration addresses. The Tier1 Plus refrigerator filters collection includes NSF 53 and 401 certified options for all major KitchenAid filter models.

Frequently Asked Questions

What water filter does my KitchenAid refrigerator use? KitchenAid refrigerators use the EveryDrop (EDR) filter series made by Whirlpool. The most common models are the EDR1RXD1, EDR3RXD1, EDR4RXD1, EDR5RXD1, and EDR6D1 depending on your refrigerator's configuration and year. The filter model number is printed on the existing cartridge, or can be confirmed using the DFS Fridge Filter Finder.

How do I reset the water filter light on a KitchenAid refrigerator? Press and hold the Filter Reset or Water Filter button on the control panel for 3 to 5 seconds until the indicator changes or turns off. On models without a dedicated filter button, press the door light switch five times within 10 seconds. On touch screen models, the reset option may appear in the Settings or Filter Status menu.

Do I need to turn off the water supply to change a KitchenAid refrigerator filter? No. KitchenAid EveryDrop filter housings are designed to shut off the water supply automatically when the cartridge is removed. A small amount of water may drip on removal -- keeping a towel nearby is sufficient preparation. No supply valve shutoff is required.

Why is my water cloudy or sputtering after I replaced the KitchenAid filter? Cloudiness and sputtering immediately after a new filter installation are caused by carbon fines and trapped air released from the new cartridge. Flushing 3 to 4 gallons through the dispenser clears both and is a required step after every installation. If the water is still cloudy after flushing, remove the filter and confirm it is fully seated and locked.

How often should I replace the water filter in a KitchenAid refrigerator? Every 6 months or at the gallon rating for your specific filter -- 200 to 400 gallons depending on the model -- whichever comes first. Households with high daily water usage, hard water, or elevated chlorine in the supply may reach the gallon limit before the 6-month mark. Reduced dispenser flow, a change in taste or odor, or cloudy ice are reliable signals to replace regardless of schedule.

What is the difference between the standard Tier1 and Tier1 Plus KitchenAid filter replacements? Standard Tier1 replacements are certified to NSF/ANSI 42 (chlorine, taste, odor) and NSF/ANSI 372 (lead-free materials) -- equivalent to OEM EveryDrop filtration performance at a lower price. Tier1 Plus adds NSF/ANSI 53 certification for lead and health-contaminant reduction and NSF/ANSI 401 for pharmaceuticals and emerging contaminants. Both fit the same housing and install identically -- the difference is the scope of contaminant reduction.

Can I use a compatible replacement filter in my KitchenAid refrigerator without voiding the warranty? In most cases, yes. The Magnuson-Moss Warranty Act generally prevents manufacturers from voiding a warranty solely because a compatible replacement part was used, provided it meets the same performance specifications. Using an NSF-certified compatible filter is the appropriate standard. Always confirm the replacement carries the relevant NSF certifications for your household's filtration needs before purchase.

What happens if I do not replace my KitchenAid refrigerator water filter on time? An overdue filter becomes saturated and can no longer reliably capture contaminants. Carbon media that is fully loaded may begin releasing previously captured particles back into the water supply. Dispenser flow rate typically declines noticeably, and ice quality suffers. Replacing on schedule prevents both water quality decline and the bacterial accumulation risk that develops in long-expired cartridges.
