chaffoteaux maury elexia comfort 24ff, intermitant fault?

When calling for hot water or heating the boiler goes through the ignition process,then locks out without ignighting, then the last 2 temperature lights start flashing. I then reset the boiler and it then sometimes will work or not,
Any ideas please

Dear Bob,
The last 2 temperature lights flashing means "Safety position for a non pilote flame detection".
The reason for that can be.
>Absence of gas
>Gas filter dirty
>Misalignment of termocouple for pilot detection
>Misalignment of ignitor in relation to ground

I hope it can help you.
Best regards,
