Hi,

Maybe it's an iffy sensor or sensor connection, which is ignored in
engineering mode but stops a normal program. Try checking voltages
at/across the different sensors before and after it halts, or
disconnecting/bypassing sensors to see whether that halts it or not.
Is there an overflow sensor that could be defective in some way?

Also check the connections at the control unit and whether the unit
itself has suffered water damage.

Thanks mate, I'll Have a look into the sensors and let you know how it goes.
