Replacement Instructions

The Classic (BI) Series water filter icon appears on the control panel when it is time to replace the water filter. To replace the water filter:

  1. To access the water filter, pull out on the bottom edge of the grille assembly, and tilt the grille frame forward.
  2. Remove the old filter by pushing the cartridge in and pull it out. Refer to the image below.
    • A small amount of water in the filter cartridge may spill out. This is normal.
    • A jar opener can help provide a better grip for a hard-to-remove filter.
    • If it cannot be removed, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
  3. Remove the new filter from the packaging and carefully remove the plastic caps.
  4. Line up the cartridge so that the locking tabs can be inserted into the filter manifold.
  5. Push the cartridge in until you hear a click.
  6. Pull slightly on the new cartridge to verify it is securely installed.
  7. Press and hold the filter reset button for five seconds to reset the water filter life monitor, as shown below.
  8. After installing a filter, clear air from the system and allow the filter to help in cleaning the water lines.
    • For non-dispenser models, discard the first two full containers of ice.
    • For dispenser models, dispense several glasses of water for a period of two minutes.

Refer to Sub-Zero Does Not Have a Water Filtration System for a list of units that have a water filter and those that do not.
