Hi there I have a smart ATO been running for 1.5 years and never missed a beat recently it has not been picking up when the water level drops below the sensor, I come home water is well below sensor level and the light on the front is still green and no alarm going off. I have cleaned the lens on the inside of the tank and the outside one and the glass is clean on inside and outside of the sump any ideas thanks

Hi Grant,

What type of ATO is this? The Micro or the regular ATO?

Where are you located?

It sounds like you need a new sensor for your ATO and you can purchase one on our website if you are in the United States. If you are let me know and I will send you the link of where to purchase.
