Mine does the same, stuck in cell reversing, DOES show flow, and voltage to cell is -23-30 VDC (negative). Error codes 125/194. My sensor appears to be working based on temperature and salt additions (salinity increase follows calculated increase based on salt additions). I cleaned my cell (no foam or bubbles) without any change. I saw in the AquaPure workbook a failure referred to as "Coating worn off of plates." My cell is old but only runs a few months a year. Could it be the cell is dead due to the low voltage codes? The story above is the same as mine except I do not have a new cell. Finally, I am making some small amount of chlorine - is that happening in "reverse" ?? Thanks in advance.
