Glowworm boiler is it faulty

[dugit]

I have glowworm ultimate 80ff .
The CH and Water tank was off this morning when I got up.
I found the pilot light was on water pump on but it did not fire up the boiler. I switched off the electrics for a few minutes then tried again but it was the same with pilot light on and water pump but no main boiler.
I switched off electrics to boiler again for about 15 minutes and when I again switched on the electrics the boiler fired up OK and everything seems to be working OK.
Was it a blip or have I got something else which is going intermittent/faulty?
Any advice most welcome

is it due a coat of looking at/checking over by a gas safe person

Fault in boiler needs looking. It will fail eventually.
Probably fan bearings are getting stiff.
