Pentair Pentair IntelliChem Chemical Controller CHLOR FEED Error Fix: Chlorine Feed Fault

The liquid chlorine (sodium hypochlorite) feed pump is not dispensing chlorine as commanded. Same troubleshooting as the acid feed pump. Additionally, liquid chlorine degrades over time (loses strength), so even if the pump is working, old chlorine may not raise ORP. Use fresh liquid chlorine (less than 30 days old for best results).
