Chlorinator TroubleshootingUpdated a year ago

If you are unsure of what make or model Chlorinator you have, please send us a photo of the chlorinator box, the cell and any stickers or labels which have details for us to assist in identifying it.

1. No Chlorine Is Present:

   • If your pool water shows 0 ppm chlorine, it’s likely a salt cell issue (dirty, damaged, or needs replacement).
   • Verify that the chlorinator is set to a value above zero (e.g., 50% is common).
   • Check all connections and look for error messages or warnings in your chlorinator system.
   • Salt cells typically last 3–5 years, depending on usage and maintenance.

2. Low Chlorine Reading:

   • After heavy rainfall or high pool usage, chlorine levels may drop.
   • Possible reasons:
     • Chlorinator setting too low (increase it).
     • Pump not running long enough (chlorinator works only when the pump runs).
     • Test different pump durations and chlorinator settings to find what works best for your salt pool.

3. Salt Levels Too High or Low:

   • Incorrect salt levels can shut off chlorine production.
   • Regularly check salt levels and inspect the cell for damage or buildup.
   • Consult your salt cell’s owner’s manual for specific error codes and solutions.

4. End-of-Life (EOL) Message:

   • If your salt cell has reached the end of its lifespan, you may receive an EOL message.
   • Consider replacing the cell with a new one to maintain optimal chlorine production and water quality. Browse replacement salt cells here
