When do you have this error - always, or after some time?
If you have this error always then missing connection on PA23 board ( connector PAC18 between pins 5 and 12 ) . Check all circuit ( PAC18 pin 5  - JD700 pin 4 - JD701 pin 2 - D701 pin 1 - sensor input - sensor - sensor output - D701 pin 2 - JD701 pin 6 - JD700  pin 10 - PAC18 pin 12.  Power off minilab and check resistance between PAC18  pin 5 and PAC18 pin 12. There should be 0 Ohm ( short circuit ) . If you have short circuit, but always see error then PA23 board will be faulty ( 113C1059637 ) .
If temperature is low, but after some time you see error then check circulation. Test and clean circulation pump, clean pipes, wash heater inside,  look do you have good circulation ( if remove filter should see liquid rotation  ) .
If you see error when temperature is too high then have check heater control circuit. Might be SSR is burned and heater always heats liquid.
