or try cleaning the photo cell for starters. just being helpful
if it doesn't lock out and the motor stays running, then probably the photocell is giving an incorrect value - replace it: could also be the motor not giving 50v on the white wire / faulty solenoid or even a faulty control box
Riello have a fault finding chart on their website (I cant link to it)
Your right on a riello but pumps running not motor and it will be a b11 not riello on a 20/25. I still think high limit but more info needed.
