How can I fix pilot light problem on Saunier Duval SD623?

I had the bolier and seem to be fine. Also added cleaner to the system which has been in about 7 days. Pilot light keeps going out and boler appears to be overheating. Plumber been back twice - cleaned again, checked seal, cleaned flue but can't find the problem. Fan appears to be working on full and half speed.

Any ideas on what the problem may be and how to fix it?

Thanks in advance
