Location:
Resistance tests have revealed no reason for fuse failure or the circuit breaker to trip. Replace the fuse (correctly rated fuse only) or reset the circuit breaker. If it fails again one of the PCBs may need to be replaced or it may be that a boiler component fails during operation i.e. fan, PCB, gas valve etc.
Upon completion of the fault diagnostics carry out final electrical safety tests and checks as per TOPs (C6).
