What you'll notice

  • Salt system error codes
  • no chlorine generation despite proper salt level
  • cell not producing chlorine

Likely causes

  • Calcium buildup and calcification on cell plates
  • age (3-5 year typical lifespan)
  • power issues or bad control board

How to keep it from coming back

  • Descale cell annually using cell cleaning cartridge
  • maintain pH below 7.8
  • replace every 3-5 years
