Tunze 3155 ATO - flashing light?

Leyth · Aug 4, 2016

Hey guys,

I just set up this ATO yesterday and it's been running fine. However, this morning I noticed the green light was flashing sporadically on the level LED. Is that normal or is something off? I don't know why I am so nervous about this particular piece of equipment.

Bump, anyone? I am going out of town and am nervous about this.

I would say Google the problem. Sorry.

Don't be sorry, thanks for trying. I did google it, it seems the only issues I have seen are that people are getting two red flashing lights. My issue is the level LED that is flashing randomly. I wonder if I have too much surface agitation that its triggering the sensor slightly and causing the led to flash because the system thinks it's about to engage?

I have a different brand of ATO, and this sometime happens to me. I just do a reset and I am one my way, sometimes it just readjusting the pump in the ATO tank, for some reason my pump will set off the alarm if the pump is not flat on the bottom of the tank. a couple of times it I have left the ATO off and the water level is low and it shuts down after filling a gallon and starts beeping and flashing. I am glad the alarms work

and it shuts down and does not over fill.

@stunreefer beat me to it, and that is were I would go after just doing a general check to see if all the parts and connected and sitting the way the should be
