thanks Roger!

i wil try the diagnostic test later today.

FWIW: it's not a siphon, the fill tube is above the water level, in an area where the level won't go up, ever, unless i overflow the tank.

bubbles: i'm also 90% sure that there are no bubbles stuck to the sensor. i've dona a visual inspection every time it overfilled the last three days.

my tank IS smaller than 50 gallons, and the section that holds the sensor is "pretty small". but up until now, this has never been a problem. i do not recall if i set the controller to nano when i installed it. do you happen to have a quick link to some instructions on how i can check/set that? i don't think that i remember where i put my manual
