First, check the exact cartridge
Compare the complete refrigerator model and the part number printed on the old filter. A generic or visually similar cartridge can leave the seal misaligned. FitsMyModel only treats a relationship as verified when the exact model, exact filter, and official manufacturer evidence agree.
Reinstall according to the manual
Remove the cartridge and inspect the seal, protective cap, tabs, and housing for damage or debris. Reinstall it using the model’s instructions. Do not overtighten a twist-in filter or force a push-in cartridge.
Check for counterfeit or unclear listings
Whirlpool warns that improperly fitted or counterfeit filters can cause leaks and recommends checking the package, seller, model number, and certification information. Use the manufacturer’s source and an authorized seller when authenticity matters.

When to stop troubleshooting
If water continues to leak, do not keep dispensing water. Follow the appliance manual or contact the manufacturer or a qualified service provider. A leak can come from the housing, head, tubing, valve, or supply line rather than the filter alone.
