KitchenAid refrigerators are designed to provide clean, filtered water and ice at the touch of a button. However, to maintain the quality of your water and the health of your appliance, the water filter must be replaced regularly. This guide explains everything you need to know about KitchenAid water filters, from identifying the correct model to troubleshooting common installation issues.
The Importance of Using a KitchenAid Water Filter
Your refrigerator’s water filter does more than just improve the taste of your drinks. It serves as a primary defense against various contaminants that can enter your home through the municipal water supply. Most KitchenAid filters are designed to reduce lead, pesticides, chlorine, and even certain pharmaceuticals.
Beyond health concerns, a clean filter protects the internal components of your refrigerator. Over time, sediment and minerals can build up in the water lines and the ice maker. Replacing the filter every six months prevents these clogs and ensures your appliance operates efficiently for years.
Identifying the Correct Filter for Your Refrigerator
KitchenAid refrigerators use EveryDrop water filters, which are the official certified filters for Whirlpool-owned brands. Because there are several different refrigerator designs, there is no single “universal” filter. You must identify which of the numbered EveryDrop filters fits your specific model.
To find the right filter, you should first locate your refrigerator’s model number. This is usually found on a sticker inside the refrigerator wall or behind the crisper drawer. Once you have the model number, you can match it to one of the following common filter types:
- Filter 1: Often used in top-freezer and bottom-freezer models where the filter is located in the upper right corner.
- Filter 2: Typically found in older side-by-side models with a bottom-grille installation.
- Filter 3: Used in specific side-by-side models with a push-button release in the bottom grille.
- Filter 4: Common in newer French door and side-by-side models with an interior filter compartment.
If you are unsure, you can also remove your current filter and look for the part number printed on the side. This is the most reliable way to ensure you purchase a compatible replacement.
When Should You Replace Your Water Filter?
Most manufacturers, including KitchenAid, recommend replacing the water filter every six months. However, this is a general guideline. Your specific replacement schedule may vary based on your household’s water usage and the quality of the water in your area.
You should consider replacing your filter sooner if you notice any of the following signs:
- The water or ice has a strange taste or odor.
- The water pressure from the dispenser has significantly decreased.
- The ice cubes appear smaller than usual or cloudy.
- The “Replace Filter” indicator light on your refrigerator panel turns on.
Step-by-Step Guide to Replacing Your Filter
The process for replacing a KitchenAid water filter depends on where the filter is located. There are two primary locations: the interior compartment and the bottom grille.
Replacing an Interior Filter (Top Right Corner or Door)
1. Locate the filter cover in the upper right corner of the refrigerator interior or inside the door. Open the cover by either pulling it down or pushing a release button.
2. Gently turn the old filter counter-clockwise (to the left) or pull it straight out, depending on the model. Some water may drip during this process, so keep a small cloth nearby.
3. Remove the protective cap from the new filter. Align the filter with the housing and push it in firmly.
4. Turn the filter clockwise (to the right) until it locks into place, or simply close the compartment door to secure it. You should feel a click when it is properly seated.
Replacing a Bottom-Grille Filter
1. Locate the filter at the bottom of the refrigerator, usually on the left side of the base grille. Some models have a push-button release, while others require a quarter-turn.
2. If your model has a button, press it firmly to eject the filter. If it does not have a button, turn the filter cap counter-clockwise to release it.
3. Slide the old filter out and remove the plastic cap from the end of the filter. You will need to reuse this cap on the new filter if it did not come with one.
4. Slide the new filter into the opening and push until it clicks or turn it clockwise to lock it. Ensure the handle is in a vertical or horizontal position as required by your manual.
Flushing the System After Installation
After installing a new filter, it is essential to flush the system. New carbon filters often contain loose carbon dust and trapped air. If you do not flush the system, your water may appear gray or the dispenser may sputter.
To flush the system, run approximately three to four gallons of water through the dispenser. You can do this in intervals (dispensing for 30 seconds, then resting for 30 seconds) to avoid overheating the dispenser motor. Once the water runs clear and the flow is steady, the filter is ready for use.
How to Reset the Water Filter Indicator Light
Installing a new filter does not automatically reset the “Replace Filter” light on your refrigerator. You must manually reset the sensor so it can begin tracking the life of the new filter. The reset method varies by model, but common steps include:
- Light/Filter Button: Press and hold the “Light” and “Filter” buttons simultaneously for three seconds until the light flashes or turns green.
- Filter Reset Button: Press and hold the dedicated “Filter Reset” button for three to five seconds.
- Options Menu: On models with a digital display, navigate through the “Options” or “Settings” menu to find the “Filter Reset” function and follow the on-screen prompts.
OEM vs. Generic Water Filters
When shopping for replacements, you will likely encounter generic or “off-brand” filters that are significantly cheaper than official KitchenAid (EveryDrop) filters. While these may fit your refrigerator, they often carry different certifications.
Official filters are NSF Certified to remove a specific list of contaminants. Generic filters may only be certified to improve taste and odor (removing chlorine) but might not remove lead or mercury. To ensure the highest water quality, it is generally recommended to stick with OEM (Original Equipment Manufacturer) filters.
Troubleshooting Common Filter Issues
If you experience issues after installing a new filter, try these simple fixes before calling for service:
Slow Water Flow: This is often caused by air trapped in the lines. Flush the system again with another gallon of water. If the flow remains slow, the filter may not be fully seated; remove it and reinstall it firmly.
Leaking: A leak usually indicates that the O-rings on the filter are not properly lubricated or the filter is cross-threaded. Remove the filter, check the O-rings for damage, and reinsert it carefully.
Dispenser Not Working: Ensure the refrigerator door is completely closed. Many KitchenAid models will disable the water dispenser if the door is even slightly ajar. Additionally, check that the water supply valve to the house is fully open.
Maintaining your KitchenAid water filter is a simple yet vital part of home maintenance.
