Having trouble getting my chlorinator to work. I've replaced the flow switch, both temperature sensors and the salt cell (T-15). Getting contradictory error messages..."Chorinator Off: High Salt/Amps"..."Check System: Low Salt". Salt level in the pool reads as 4000ppm with my portable salt sensor and similar with salt strips. Diagnostic on the controller says 1700ppm (+40.43V, 10.05A). I think the controller is an AquaPlus. Main Software Revision 4.45. Display Software Revision 3.12. Installed in 2014. Any help on troubleshooting appreciated. (Will be diluting the pool in the mean time).
