Your cell needs cleaning. Remove it, rinse with a hose, and acid-clean only if scale remains.

The cell needs cleaning. Clean it per Section 6.3.
Turn the pump off and open the filter air relief valve.
Shut down and release pressure.
Jandy warns that the pump/filter system is under pressure, and pressure must be released before removing components.
Remove the cell, look between the plates, and clean scale or debris per Section 6.3.
Inspect and clean the cell.
Jandy Section 6.3: first try a high-pressure jet of water from a garden hose. If that does not clean it, plug the two adjacent ports, mix one pint of muriatic acid into two quarts of tap water, and pour it into the cell. If vigorous foaming does not begin, the cell does not need acid cleaning. Otherwise leave it until foaming stops, but never more than 1/2 hour; excessive acid washing damages the cell. Rinse thoroughly, inspect, and reinstall. Do not put the sensor in acid.
Scale comes from hard or unbalanced water. Adjust alkalinity, then pH.
Correct water balance.
Jandy troubleshooting: adjust total alkalinity to 80 to 120 ppm, then pH to 7.4 to 7.6. For high total hardness, dilute with fresh water and ask a pool professional about a sequestering agent. If acid washing was needed, the manual recommends having a water sample analyzed for hardness and balance.
