Boiler Main Burner Issues

[covkid1972]

Hi people,

could anyone offer info on a problem i am encountering with my Baxi Boiler.
I noticed this morning that the water wasnt getting very hot. So I checked the boiler, the pilot light is on but the main burner doesnt seem to ignite.

Ive done a switch off on the boiler and then restarted it. I then turned the hot water on and the main burner ignited for around 30 secs but then went out again.

Anyone got any ideas on what the issue could be?

What model of baxi is it? is it wall mounted, or a back boiler, is it a combi?
more info please if its a back boiler unit it could be something simple like a pump not circulating water away from the boiler so it is coming up to temperature and then shutting down
