Sub-Zero Water Filter Replacement Indicator Shown While Unit Powered by Generator


  • Would running a Sub-Zero on a generator while experiencing power outages cause the water filter replacement indicator to continually return after being reset?
  • How to replace water filter
  • Generator-Inverter Considerations

Steps to Verify Issue:

  1. Operating a Sub-Zero on a generator is not recommended.
    • Refer to the product Installation Guide for further electrical requirements.
    • Reset the water filter indicator if it appears.
  2. It is possible that the water icon displayed while being powered by a generator is coincidental, and the water filter truly does need to be replaced.
  3. Replacement water filters can be ordered from the Sub-Zero accessory store, or from a Factory Certified Parts Distributor.


If these steps do not resolve the issue, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
