There are several yellow/orange lights so which one. Is the red one also lit?

It could be flame detection, failed pump, over heating, sticking diapragm etc.etc.

Probably needs a clean of the ignition electrodes.

2 triangle lights - I'd reckon flame detection failure. The user instruction (small booklet) should say, what is meant by the Please don't top post.
