My Zodiac LM2-24 SWG recently (last 2 weeks or so) stopped generating chlorine. There is no chlorine at all in my pool. Across the top of the control panel the indicators are as follows from left to right: Chlorine Output glows amber; Super Chlorinate is green, Add Salt is amber, but my salt reading is 5,000 ppm and the manufacturer's manual recommends a minimum of 4000 ppm, and the No Flow light is red, although the pump is working fine. Both the salt and the chlorine readings came from a test at the local Leslie's Pool store. Also, pressing the on/off button doesn't do anything. In the past when this happened I could clean the cell using diluted muriatic acid to get rid of the calcium buildup and that would fix it. No luck this time. The cell is 3 years old. Any suggestions are greatly appreciated.
