Replacement filter doesn't fit in your refrigerator

Closeup of a Samsung water filter in front of a refrigerator

You've just got yourself a new filter for your refrigerator and you take the old one out, but the new one just doesn't want to go in. Relieving the water pressure will help (turn off the water supply and dispense water until it stops). If the new filter refuses to go in, either your new filter or your old filter is not a Samsung brand filter.

Always use Samsung brand filters. Filters from other manufacturers, even if they indicate compatibility, may damage your fridge and water filter housing, or break off and leave pieces of the filter inside (like the cap), preventing a new filter from being inserted.

A few years ago, the HAF-CU1 model's design was changed from a 2-rib lock to a 3-rib lock in order to provide a tighter fit and better seal. However, the new filter design will still fit in older models of refrigerators, which is why the model and part number was not changed. The first time you switch to the 3-rib type, you may need to perform the "fully unlock the housing" procedure described here, even though the old 2-rib type was also a genuine filter.

If the old filter inserts easily but the new filter does not, it is because the old filter is not opening the locking mechanism all the way to make room for the correct Samsung brand filter. It only opens the lock enough for itself to get out.

To fix this, hold the old filter in the locking mechanism and turn it all the way open before letting it come out. This is sort of like using the old filter as a screwdriver to open the lock all the way. The steps are:

  1. Temporarily reinstall the old filter.
  2. While pressing the filter into the housing, turn it to the left as far as it will go, even past the point where the filter could be removed, until the filter can no longer be turned left while held into the housing.
  3. Remove the old filter, and install the new filter.

If this method does not work, or the old filter is no longer available to use, visit our Support Center to request service.
