Sorry for the delay so you dont have any other symbols shown on the display just 0 0 0

If your not getting any other symbols that points to a fault on the control board, since anything else would show a fault code, or show you the radiator and rap symbol to show its in standby.

Before replacing the PCB its worth getting the gas engineer to verify all the connectors on the PCB are correctly seated before restarting it.
