Mend TEC Vailant Eco Tec

How can I fix my Vailant Eco tec plus 438?

I've recently moved in and inherited the above boiler which worked really well up until this morning. I am getting a symbol and a code F 28 which I've learned from the internet means the pilot light will not ignite, although I can't find instructions on how to resolve.
Is there anything I can try prior to calling in a professional ?
I'd be really grateful for advice.

Ignition fault
The boiler book will list all the possible causes of an ignition fault but you would require appropriate equipment in order to test components

Q

On nearly all boilers the pilot flame will only light if the fan is running and has been recognised by the air pressure switch inside the enclosure - there is not much you can reasonably do if you want a quick fix.

I get the impression that if you call British Gas they will want to sell you a new boiler and flush your radiators too - they tend to up-sell.

Ask a neighbour for a recommendation
