Report "I have a Zodiac lm3 24... when the chlorinator cahnges polarity ever 2nd time the no flow light and comes on and the output is a solid orange. Water is flowing around the cell but the chlorine generation has ceased. When it chnages poIarity a 2nd time it works ok, hence it only produces chlorine from one pole. I only replaced the cell 12 months ago so could it be the PCB power board?"
