5 year old Jandy Aqua Pure 700 system. Stopped making chlorine a couple weeks ago. I found the troubleshooting manual online and went through it. I've pretty much narrowed it down to the front board or Flow/salinity sensor. The front board runs about $275 and the Flow sensor $180. Each is non returnable. I'd really like to narrow the problem down as to not waste $$ on a 50/50 shot and getting the right one. Jandy tech support was no help as my system is not under warranty.

The most aggravating part of this and maybe a clue as to the problem is the salinity reading the machine is showing. It is showing a reading of 13.6 (Waaaay High) but I have tested the water myself and had a pool place test it and I am right at 3.0 where I should be. When try to enter the calibration screen on the unit to calibrate the salinity, it won't adjust.

I appreciate any help!
