I have had an Apex EL ATO that worked great for a bit....then randomly stopped working and started sending me a crap ton of notifications when it stopped working...Error ATO pump. I did everything I think I could to check to make sure there was nothing wrong with it, I checked tubing, I cleaned sensors, pump never ran dry, and everything was great minus a little buildup on sensor on the inside of sump. I changed the time from which the ATO ran from 60:00 to :01 to make sure it actually works when needed, it and does....so I have no clue why the ATO error keeps coming up...Please help.
