Refrigerator water filter leaking: causes and fixes

Short answer: Most leaks at the filter come from a filter that is not fully locked in place, a damaged or missing O-ring, or a filter that is not the right part number for the housing. Remove the filter, check the O-rings and the part number, and reinstall it until it locks. If water still leaks with a correct new filter, the filter head or housing may be cracked and need service.

Safety: Unplug the refrigerator before mopping water around the base or reaching behind it.

Step by step

  1. Shut off water if it is pouring. Close the valve feeding the refrigerator and put towels down.
  2. Remove and inspect. Look for torn, flattened or missing O-rings and for cracks in the filter.
  3. Confirm the part number. Match it exactly to your old filter or manual, for example LT700P or EDR1RXD1.
  4. Reinstall firmly. Push or turn until it locks, then flush and watch for drips.
  5. Check the head. A leak from the filter head with a correct new filter usually means the housing needs repair.

Genuine and replacement filters

Common questions

Why is my new fridge filter leaking but the old one didn't?

It may not be fully seated, an O-ring may have rolled, or it may not match your housing exactly.

Can I reuse O-rings from the old filter?

O-rings are part of the filter. Use a new filter with intact O-rings.

Are genuine filters better at sealing?

Genuine OEM filters are made for the housing. Replacement filters list what they are designed to fit; match the part number exactly either way.
