Turned it on when I got home, it immediately topped off to just above the top sensor, pump then shut off, no siphon activity, and then the alarm went off ?
No where in the thread did I read if the pump is running or not while this happens. If the pump is running and not shutting off when the water hits the first sensor, bad first sensor or ATO control unit. I would first unplug the sensors from the unit and the unit from the wall, then plug every thing back in.
