I have a goldline/aqua rite unit. Going on 2 years this month. I am not getting any trouble codes, but I noticed when generating on one polarity... Volts 28.2, current 1.59, salt 1700. On the other polarity: volts 26.5, current 3.88, salt 2900. I pulled the cell off and did an acid clean ( first time and there was some buildup). But after the clean, same thing. Has anyone else had this issue?
