I have a brand new Osmolator Nano that I hooked up yesterday but didn't plug in until today as I needed to fill my ATO reservoir. When I plugged in the Osmolator today, the sensor was above the water line. I figured I would plug in the Osmolator and let it fill. I plugged it in and only got about a half second pump of water and nothing more. I then checked the that the float sensor was working by activating and deactivating the float switch manually. I could hear it clicking in the relay. I then unplugged the unit and plugged it back in and got the same half second response. At this time I had to fix my main return pump so I unplugged the pump which filled the sump above the Osmolator's float switch. When the return pump was plugged back in and the water line fell below the float sensor there was another half second pulse of water and that was it. Are there any other troubleshooting techniques I could apply?
