My Aquapure system is giving me some codes regarding a flow sensor service (172, 185, and 186) and when I press the temperature button I get a HH code which my installation manual says that "Input has exceeded Maximum Range" whatever that means. On another thread I noticed that someone else pressed some other control panel buttons that he read about in a troubleshooting manual they picked up online. I've not done any of that because I cannot find any manual but I did check the cleanliness of the sensor, made sure it was plugged in properly, and did some resetting of the buttons on the Tri-Sensor Adapter all of which provided no help. I have replaced the chlorine generator and it's sensor a couple of years ago. Any suggestions?
