Service a salt chlorine generator: inspect the cell, assess scaling, and decide whether replacement is needed

Steps

1. Check the controller display/error codes for low-salt, high-salt, or inspect-cell warnings before physically inspecting the cell
2. Remove the cell and visually inspect the electrode plates for calcium scale buildup, which reduces chlorine output and can eventually short or damage the cell
3. Clean light-to-moderate scale per manufacturer instructions (typically a diluted muriatic acid soak or pressure rinse), then reinstall and retest output
4. Test salt level with a dedicated salt test kit/meter and adjust to the manufacturer's specified range for that model, since incorrect salinity affects both output and cell life
5. Inspect for pitting, flaking, or worn plating on the electrodes — physical degradation, not just scale, signals the cell is nearing end of life
6. Compare actual chlorine output against the cell's rated output; if output stays low after cleaning and salt/pH correction, recommend cell replacement
