Without knowing exactly which model cell you have, the follow steps cover a large number os situations what will cause error lights on a salt system. Check them in this order
Verify the salinity - Perform independent tests to ensure that the pool water's salinity is in range (recommended: titration-based chemical test, or else a recently-calibrated digital test).
Inspect / clean the cell - Ensure that the cell is fully cleaned (multiple times in a row if necessary, so that when fresh cleaning solution is added there is no "fizzing"). Flush cell thoroughly with a hose-end nozzle.
Check the connections - Ensure that all connections and cables are fully tight, fully seated, and free of debris or damage.
Check the water level / flow - Ensure that water is completely filling the Cell throughout daily operation, esp. if getting daily repetitive warnings.
Check the controller setting (if applicable) - Ensure that the controller has not inadvertently been changed to a different cell-type setting.
Check the water temperature - Ensure that the water is within normal operating temperatures (typically high 50's to 130's F, depending on model).
After checking the above - Power the unit off and on to confirm; if the cell is depleted, and all other issues have been resolved, any warning will come on within the first 1-5 minutes or so of turning the unit on.
