Product Overview
The Obida WP12664501 Filter Bypass Cap is designed to replace the water filter in compatible refrigerators, allowing the appliance to dispense water without a filter installed. This is useful when you prefer to use unfiltered water or when a replacement filter is not immediately available. It ensures continuous water flow from your refrigerator's dispenser.
This bypass cap is compatible with select Whirlpool, Maytag, Amana, and Kitchen Aid refrigerator models that utilize the EveryDrop Filter 4 (UKF8001, EDR4RXD1) water filter. It replaces original part numbers W11395888, WP12664501, and 12664501SP.

Installation Instructions
Follow these steps to properly install the filter bypass cap in your refrigerator. Before beginning, ensure you have disconnected power to the refrigerator and turned off the water supply line.
- Locate the Filter Compartment: Identify the water filter compartment in your refrigerator. This is typically located in the upper right corner of the fresh food compartment or in the base grille.
- Remove Existing Filter: If a water filter is currently installed, twist it counter-clockwise to unlock and pull it straight out. Be prepared for a small amount of water to drip.
- Insert Bypass Cap: Align the new Obida WP12664501 Filter Bypass Cap with the filter housing. The cap is blue and features a handle for gripping.
- Secure the Cap: Push the bypass cap firmly into the housing. Then, twist it clockwise until it locks securely into place. You may hear a click. Some users have reported a very tight fit, potentially requiring the use of pliers for leverage to fully seat and turn the cap. Ensure it is turned all the way to prevent issues with water flow.
- Restore Water and Power: Once the bypass cap is securely installed, turn the water supply line back on and reconnect power to the refrigerator.
- Flush the System: Dispense approximately 2-3 gallons of water from the refrigerator dispenser to flush any air from the system.


Operation
Once the bypass cap is installed, your refrigerator's water dispenser will function normally, providing unfiltered water. The appliance will no longer detect a filter, and any filter change indicators should reset or remain off.
Note: Some users have reported a reduced water flow rate after installing a bypass cap compared to a filter. This can vary by refrigerator model and water pressure. If water flow is significantly reduced, ensure the cap is fully seated and locked into place.
Maintenance
The Obida WP12664501 Filter Bypass Cap requires minimal maintenance. If removed for any reason, it can be cleaned with mild soap and water. Ensure it is thoroughly rinsed and dry before re-installation or storage. Store the cap in a clean, dry place when not in use, especially if you plan to re-install a water filter in the future.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No water or very slow water flow from dispenser. | Bypass cap not fully seated or locked. Air in the water lines. Water supply valve is off. | Ensure the bypass cap is twisted completely clockwise until it clicks. You may need pliers for a tight fit. Dispense several gallons of water to purge air. Check that the refrigerator's water supply valve is fully open. |
| Difficulty installing the bypass cap. | Tight fit due to manufacturing tolerances or design. | Apply firm, steady pressure while twisting clockwise. If necessary, use a pair of pliers to gently assist with the final turn to ensure it is fully seated. Avoid excessive force to prevent damage. |
