Saniclear 40 jacquzzi system for my pool hit error code

Apr 18, 2018
I recently am getting a error code hot on my Saniclear 40 jacquzzi system. My pool has turned green and not making chlorine. The pool guy came out and told me I need to replace my motherboard but all the information I've looked up online says I need to replace the cell and since I'm not made of money I'm not sure who to believe replacing motherboard or the cell what ayou what is your opinion?
