What does a flashing green light mean?
The self-diagnostics in your SCU will cause the green light located on the housing to flash when your SCU needs attention. Slow Flashing Green Light: Check the pH and salt level, then clean the cell. Fast Flashing Green Light: If proper pH and salt level is maintained and cleaning the cell does not correct it, the fast flashing green light means the cell has worn down to the extent that your SCU cannot generate enough chlorine to sanitize your pool. Replace the worn cell with a new one.
