ignite

Hi Can someone please help, my Worcester Junior 24i boiler is not Igniting. The pressure did drop before I noticed and I've fixed that. Now there's no green light but I hear a lot of ticking after I reset it. I think the pressure dropped because we turned on a rad that was off for a long...

I have Kingfisher Mf RSL 100 boiler which stopped to ignite and does so only on rear occasion. Once HW or CH is switched, motorised valves work, then fan starts, one click can be heard and that is it. It doesn't try to ignite again and fan will keep on working until HW and CH are switched...
