Worcester Greenstar 30Si Mk IV boiler dead boiler!

[crikey876]

My inline fuse was blown for my boiler as there was no light on the switch, I replaced it and light returned to the switch only. The boiler did not light up in any way, nothing, dead.
Can anyone throw some suggestions my way?
Pressure was low but I topped it up, gas is good.
I don't know where to look next

Fuse blows for a reason, probably due to a fault within the boiler. You need a boiler engineer to visit and establish what is amiss .

Okay, thank you. The boiler was not in use today, so it's strange
