Duetto ATO Fails After 3 Years

[Big Mistake]

Just a notice to marine persons.

My Duetto ATO failed after 3 years. (2 years 10 months.)

Power supply, pump, and electronic unit seem to work.

I suspect the infrared LED has failed in the sensor (probably on 24 hours a day.)

FYI, I have replaced it with another Duetto ATO - so I have some spare parts, and a tank that was already setup for a Duetto ATO.

Ezy Pzy install. :cool:

It served very faithfully. As soon as it was gone, realize how diligent the ATO is at keeping the tank filled and salinity stable.

I do have a cold spare backup heater. And a spare pump. And I have dual lights on the tank.

Mine is about that old and seems to be on its way out as well. Sometimes it works, sometimes it doesn’t.

Mine just failed after EXACTLY 3 years.

Light turns on the actual device, it beeps and all, but no water movement/taking magnet out of the sump triggers it to kick on the pump.

Just bought another.. just one of those things in this hobby I guess - ATOs eventually fail.

As long as they fail OFF, not ON :-)

My replacement is still chugging along, so it has 2 more years :)

Heater and pump still going. I have high hopes for the Cobalt Neo_Therm but that could be a ...

Mine just failed ON. Luckily the controller detected that it was running longer than normal and started beeping.
