I have a 3+ year old intellichlor IC40, installed in August 2010. After opening my pool this year, the "Cell" light is blinking green, which signifies no chlorine is being generated. All other lights on the chlorinator are green. I've cleaned the device using both high pressure garden hose as well as the suggested muriatic acid solution. After re-installing the chlorinator, the "Cell" light stays solid green for a couple of minutes before returning to the problematic flashing state.
When visually inspecting the chlorinator, there is no build up.
When I hold down the "More" button to determine end of life, it goes to 60%.
What else is there to do to remedy or repair? Or am I stuck having to replace?
