KitchenAid Refrigerator Water Filter Bypass Plug Replacement

KitchenAid Refrigerator Water Filter and Bypass Plug Parts

Your KitchenAid refrigerator's water filter keeps ice and drinking water clean and fresh. When the filter cartridge reaches its limit, or if you prefer unfiltered water, the bypass plug steps in as a safety part. Genuine OEM filters and bypass plugs ensure proper water pressure, flow rate, and seal integrity — aftermarket filters can restrict flow or leak, triggering error codes on factory-certified KitchenAid models.

Water filters are typically replaced every six to twelve months depending on usage and water quality. If your ice maker produces less ice, water dispenser trickles, or you see error codes on the display, the filter may be clogged. A bypass plug lets you skip filtration without leaving the filter housing empty.

• Filter cartridge won't seat or dispenser trickles slowly: filter is clogged or seated incorrectly; verify model for correct cartridge type
• Refrigerator displays filter code or warning light: cartridge reached lifespan; replacement required to clear code
• No water or ice after filter replacement: bypass plug installed backward or filter housing cap loose; reseat firmly
• Water tastes off or smells like plastic: old filter needs replacing; NSF-certified OEM filters maintain water quality
• Filter housing leaks or drips water inside fridge: O-ring worn or filter not fully seated; OEM filter with new O-ring seals the leak

Find your exact KitchenAid model number on the interior wall (usually behind the crisper drawer or on the side wall) to select the correct water filter or bypass plug. Enter it in the model lookup tool to confirm compatibility and see all available water system parts for your refrigerator.

KitchenAid Refrigerator Water Filter & Bypass Plug FAQ

How often should I replace my KitchenAid refrigerator water filter?

OEM KitchenAid filters are typically good for six to twelve months of use, depending on water quality and household consumption. If your dispenser trickles, ice production drops, or the filter indicator light comes on — replace it immediately. Using an expired filter reduces water quality and can restrict flow enough to trigger error codes on factory-certified models.

What's the difference between an OEM water filter and an aftermarket filter?

OEM KitchenAid water filters are engineered specifically for your model's inlet pressure, flow rate, and seal dimensions. They carry NSF certification and maintain proper flow to the ice maker and dispenser. Many aftermarket filters restrict water pressure, cause dispenser sputtering, or fail to seal properly — leading to leaks inside the refrigerator and voiding your manufacturer specifications. For factory-certified KitchenAid models with electronic controls, a weak filter signal can trigger error codes that only go away with an OEM cartridge.

Can I use the bypass plug permanently instead of buying filters?

Technically, yes — the bypass plug allows unfiltered water to flow when no filter is installed. However, this delivers unfiltered tap water to your ice maker and dispenser, which can introduce sediment, chlorine taste, and mineral buildup over time. If you prefer unfiltered water, confirm that's your choice; otherwise, a fresh OEM filter protects both water quality and appliance longevity.

How do I find my KitchenAid refrigerator model number for the correct filter?

KitchenAid model numbers are printed on a label inside the refrigerator — usually on the interior wall behind the crisper drawer, on the side wall, or inside the freezer compartment. The format is typically KRFF (French door) or KRSC (side-by-side), followed by a series of numbers and letters. Enter your full model number in the Repair Clinic lookup tool to see the exact water filter, bypass plug, and all compatible water system parts for your refrigerator.

KitchenAid Refrigerator Model Number: Where to Look

KitchenAid prints the model number on a label inside most refrigerators, commonly behind the crisper drawer, along the side wall, or on the ceiling of the fresh food compartment. Check the freezer compartment too if you do not find it in the refrigerator section. Copy the complete model number, including every letter and number, since similar KitchenAid refrigerators can use different parts. Enter it in the model number search to pull up the parts matched to your unit across the full refrigerator catalog, including water system parts and other replacement parts. This quick step narrows your results to your exact model and helps prevent ordering a part that does not fit.
