Note:
Fuses blow due to either fatigue (age) or excessive current which is an indication of a further fault.
Fatigue - change fuse, boiler should function.
Please CLICK HERE to replace the fuse and retest the boiler.
Excessive load - resistance checks should be carried out on the appliance components.
The fan, pump and gas valve solenoids should be checked for short circuit.
If these components are satisfactory a more detailed inspection of the wiring and switching needs to be carried out, checking for signs of damage, water ingress or arcing.
