We use the Autopilot Nano to sanitize our small 10K gallon in-ground pool. It's not generating chlorine at present and I'm really doing some serious investigation as to why not. The unit is a little less than two years old and has been in continuous service for about 15 months. Right now the red error light is blinking. It says purifier off, check flow, or something like that. In reality, the flow is better than it's been in a long time, the filter is clean, the salt level is 3600 ppm per Taylor chemical test. The water temperature is 72 degrees. If I go through the Autopilot test functions, the screen tells me that voltage is 0 (zero) which makes sense if the salt cell is "off." It says the salt level is 1100 ppm and I should add a couple of bags of salt, and the temperature level reads 92 degrees. So, without getting too excited, I asked myself, what do these readings have in common?? They're all processed by the tri-sensor circuitry. I have a spare manifold with tri-sensor so I will install it this afternoon to see if the problem follows the manifold or maybe it's in the first circuit board where the tri-sensor cable attaches.
For the past two weeks, I haven't gotten excited or upset because for the past two weeks I've noticed that when the pump and chlorification system first start up, I could pat or thump on the lower right corner of the Nano case cover and the unit would start working fine and continue until the next day when the startup occurred. It sure sounds like a sticking relay or intermittent connection to me.
Where do I go from here. Have any of you had problems with the tri-sensor circuitry? Thanks for reading and please let me know if you have any thoughts.
