Low Salt (Solid or Flashing) – Error Light
When this LED is illuminated, salt may need to be added to the pool.
Troubleshooting:
• The pool’s salinity level may be getting low. Independently measure salt level and adjust to 3500-4000ppm if needed.
• If the salinity level independently tests in range, the cell may be accumulating mineral scaling or other debris that
needs to be removed. Clean the cell according to the instructions on page 4.
• If the salt level is ideal and the cell has been thoroughly cleaned multiple times in a row, the cell plates may be partially
depleted and the cell is coming near to the end of its useable lifespan.
• Additional Troubleshooting: The Control Module is programmed to match the size of the Cell model. If a different size
Cell has been put on or if this setting may have been unintentionally changed, follow the Reprogramming instructions.
Check Cell (Solid) – Error Light
When this LED is illuminated, the cell may need to be cleaned.
Troubleshooting:
• Double check the pool’s salinity level. Independently measure salt level and adjust to 3500-4000ppm if needed.
• If the salinity level independently tests in range, the cell needs to be cleaned to remove mineral scaling or other debris.
Clean the cell according to the instructions on page 4. Inspect the cell after cleaning to make sure nothing is stuck
between the plates. Sometimes multiple cleanings in a row are required; mix a new batch of cleaning solution and let
it soak inside the cell. If “fizzing” still occurs, repeat the cleaning process with new solution each time until fizzing no
longer occurs when new solution has been added to the cell.
• If the salt level is ideal and the cell has been thoroughly cleaned multiple times in a row, the cell plates may be depleted
or damaged and the cell has reached the end of its useable lifespan. If damaged, inspect the cell for plates that are
damaged, deteriorated, pitted or physically worn. If so, this indicates corrosive water chemistry (low LSI) that needs
to be prevented through regularly ensuring proper water balance.
• Additional Troubleshooting:
• Is the pool losing prime and/or is low-speed pump operation causing air to accumulate in the Cell?
• Has the salt system been run without any pump operation? If the cell has a white milky coating and is no
longer clear, the Flow Sensor should also be checked for failure.
• Has a new Cell been installed after replacing a depleted Cell? Allow the system to run for at least 45
minutes and the “check cell” LED should go off.
