What would cause the high salt light to flash when the salt is not high? The board says salt level at 9900ppm!
All other lights on IC40 are green. FC at 1.5.
I tested using a salt strip and reading was 750ppm! Shouldn't it have shut off at that level?
The IC40 was just installed last fall.
Pool guy came out last Saturday and said it was working fine. Obviously not.
Salt = 830
FC = 1.5
TA = 120
CYA = 30
