I have my ATO3155 work for almost a year, but last week it keep sound alarm constantly. I have to unplug the power and put it back on every time the alarm trigger. Every time I plug power back, it pump for 15 sec as usual, then the low water level light is on then the pump start pumping water but the alarm turn on after 3 second and the unit start sounding alarm.
I took it off, soak the pump, optical sensor and the floating in vinegar for 1 hrs, I put everything back on but it still the same issue.
What is the problem? how to fix it?
