Jandy AquaLink RS / iAquaLink WiFi-Enabled Pool & Spa Automation Controller with Mobile App Control HIGH SALT Error Fix: Salt Level Above Maximum

Error code HIGH SALT on the Jandy AquaLink RS / iAquaLink WiFi-Enabled Pool & Spa Automation Controller with Mobile App Control means: Salt Level Above Maximum. The salt concentration in the pool water exceeds the recommended maximum (typically above 4,500 ppm) — excessively high salt accelerates corrosion of metal pool equipment, ladders, and fixtures, and can damage the salt cell; the only way to reduce salt concentration is to partially drain the pool and refill with fresh (unsalted) water; salt does not evaporate; there is no chemical additive to remove salt; calculate the amount to drain based on current salt level and target level
