System Error 2 – Over-Current or Debris
If a System Error 2 is illuminated, it is critical to check and fix these issues before proceeding.
Turn off pump and salt system. The following issues will commonly cause this error.
• Check cell for any debris or foreign object that may be lodged between plates. Use a high
pressure garden hose to get it out, do not stick anything between plates. If mineral scale is
present, clean the cell according to the instructions in the manual.
• Check if cell plates are damaged, deteriorated, pitted or physically worn. If so, this indicates
corrosive water chemistry (low LSI, preventable) and the cell must be replaced.
• Check all cable connections and clean if necessary to remove any corrosion or debris.
