    What to do if my Zodiac Control Unit shows a 'NO FLOW' error?
    • S

      If your Zodiac Control Unit displays 'NO FLOW,' it could be due to several reasons. The filtering pump may have stopped or failed, there might be air or gas in the cell, or the by-pass valves might be closed. Start by checking the pump, its programming clock, the filter, the skimmer(s), and the by-pass valves, and clean them if needed. Also, check the cable connections for the cell and flow controller. If necessary, replace the flow controller.

    Why does my Zodiac Control Unit say 'CHECK SALT'?
    • M

      If your Zodiac Control Unit displays 'CHECK SALT', it could be due to a few reasons. It could be due to lack of salt (less than 3g/L) because of water loss or dilution. Add salt to the pool to maintain a level of 4 g/L. Also, if the pool water temperature is too low (less than 18°C), reduce chlorine production or add salt to compensate. Lastly, the cell might be scaled up or worn, in which case you should clean or replace it.

    What does 'OUTPUT FAULT' mean on my Zodiac Control Unit?

      changshannonAug 7, 2025
      If your Zodiac Control Unit displays 'OUTPUT FAULT', it could be due to a short-circuit in the cell or a disconnected/badly connected cable. Begin by checking the cell connections. It could also be due to a worn electrode, in which case you should replace the cell. In some cases, it could be due to insufficient salt. If necessary, have the control box (electronic board and transformer) checked by a qualified technician.

    How to fix 'HIGH SALT' error on Zodiac Control Unit?

      Jeffery JonesAug 11, 2025
      If your Zodiac Control Unit indicates 'HIGH SALT', it means the salt level is too high (over 10 g/L). To fix this, you will need to drain part of the pool water to lower the salt concentration.

    What does 'FLASH' mean on my Zodiac Control Unit?
    • D
      Donald LoganAug 16, 2025
      If your Zodiac Control Unit displays 'FLASH', wait about 10 minutes. Chlorine production should resume automatically at the previously set level.

    Why does my Zodiac Control Unit keep losing the time setting?
    • J
      Joseph JonesAug 22, 2025
      If your Zodiac Control Unit is losing the time setting, the accumulator is likely worn or defective. Check the condition of the accumulator and replace it if needed with a 3V accumulator, type "CR2032".
