TUNZE ATO TROUBLE SHOOTING

Hey guys
Been having a lot of trouble with my Tunze ATO since I moved to new house. The tap off never shuts off til the alarm goes off now, Ive never had this issue before and soaked the shit out it in Vinegar and adjusted it a few times but for some reason cant get it... any suggestions?
 
I had the same issues many times. I had to send my unit in to Tunze use for inspection repairs. Last 2 times it was the optic eye. The repairs are not free or warranty. I had to pay both times, but I guess it was still cheaper than buying a new unit.
 
You might need to tune it back to the smaller tank setting which decreases the minimum amount of water pumped per top off.
