From what you are explaining it sounds like you have the Pentair intelliChlor salt cell?
If they are flashing red and green – you have too much salt and need to add water to your pool to dilute the salt. Either take a reading from in your control panel if you have the easytouch, or use the test strips to verify your level is too high.
Another step is to turn your entire system off and back on which I have found may sometimes help reset things.
Check to make sure your salt cell is clean and doesn’t need an acid bath of 1 part muriatic acid to 5 parts water for approx. 20 minutes.
If the flow light is red, that means the water flow is too low to operate properly. Check for blockages. Also clean your skimmer, pump, and perform a backwash or cleaning of your filter. Once those are done if your flow doesn’t turn green you have an issue with the cell itself.
The intelliChlor series looks for a salt ppm of 3600 as ideal. If you have more you’ll have to determine if you can just add fresh water, or drain some of your water and refill.
To assess how much life a Pentair intelliChlor Salt Cell has left, first press and hold the more button for three seconds. The unit will check the status and display a percentage of life that the unit has operated. 20%=2000 hours. You have until the unit goes to 100% of life status before you need to replace the cell.
