New Kamoer ATO malfunctioning

[laezur]

Just setup the Kamoer auto top off and run believe the optical sensor is broken, does anyone have one and might have experience with this?

My issue appears to be as such - Initially the ATO will successfully fill to the optical sensor level, and then stop. A few minutes later, it will then begin to continue filling until the fail safe float valve cuts it off and the alarm begins to go off to alert me to potential overflowing.

I can unplug it, and it will repeat this process.

Is it the optical sensor that’s broken? Maybe some water got inside the sensor since it appears the rubber O-Ring may have been broken?

Your best bet is to contact Kamoer directly.

I’ve just replaced with another Kamoa… same thing is happening.

After an hour or so it just randomly starts filling up and doesn’t stop until it hits the float switch, why is the optical sensor so bad on this???

Either I’m missing something or this is the worst piece of equipment on offer

Tried moving the float switch away from the optical sensor which doesn’t seem to help

I’m having the same thing happen to me. Did you discover what was happening?

It was two things.

Initially, I had broken the O-Ring seal on the optical sensor which I believe allowed water to enter the sensor so it would send it haywire.

If the O-Ring looks intact, I had a second issue after replacing it (in which the same issue arose) and I found out that was due to micro-bubbles produced from my skimmer. It does say in the manual that micro bubbles can cause it to run endlessly or run when not needed. I would look to eliminate micro bubbles if you have any.
