Fan tries to run every 15 seconds then stops immediately?

I have an Ideal logic system boiler which will now not ignite.
The fan tries to start every 15 seconds then stops instantly even when the boiler is turned off on the boiler panel.
I suspect it could be a pcb malfunction but any suggestions otherwise more than welcome

Legally the only person who can work on a gas boiler is a Gas Safe certified engineer.
