Has anyone had difficulty with their innovative marine hydrofill ATO not pumping? My ATO shows the water level as low on the LED indicator but does not pump to fill the tank. I've checked the sensors and they appear to be clear of buildup. Any ideas?
Use ac voltage meter to check for AC voltage at the plug that goes to the pump..
If there is voltage there then the pump may be burned out..
If there is not then the relay inside the ATO unit may have failed..
