The unit shows 100% on the display and no error codes unless I need to push a series of buttons to show the codes of which I do not know which buttons. Manual doesn't talk about pushing any buttons to display error codes.
The Power On LED is lit but no other lights are on. The pool water has been tested and the salt level is around 3000. However there is NO chlorine in the pool per the water test I ran.
Right now I am leaning towards a bad board since I have no LEDS lit other than the Power On LED. Display shows 100%. I did inspect the cell and it's clean. I did set it to Boost as well but going to shock pool as I see algae.
How can I troubleshoot the unit further?
