The system shows Inspect Cell and Check Salt and will not allow a recalibration.
Leslie Pool chemical analysis shows salt to be at 2650. System shows 77P.
Because Hayward doesn't list a manual for this model I was using the Aqua-Rite manual to attempt calibrating my system. (Switch off then on and wait for click). The system does not count down as shown in many videos.
If my motherboard is bad, I'd like to know how I can check it before I order a new one. The system was installed 3 years ago in March.
