You can tell if your Pentair salt cell is bad if your pool is not generating chlorine, and the control panel shows warning lights or error codes like "Low Salt," "Check Cell," or "Cell Fault." Additionally, inspect the cell for excessive calcium buildup or visible damage. If cleaning the cell and resetting the system doesn't resolve the issue, the cell likely needs replacement.
