My Ichlor 30 chlorine generator has no lights. The Power Supply (wall mounted) is supplying 32VDC. The chlorine option is turned on in the Easytouch control system but the Chlorinator display shows 0 salt level. Question is: Can a defective flow switch cause this or do I have to replace the unit. Other than this anomoly, the rest of the system is functioning properly, pumps, etc. Appreciate any input.
