Hi, Can anyone please help resolve my combi-boiler problem? Following replacement of the pcb my boiler now fires up for CH but after 10-20 seconds it cuts out..... then it repeats the same process over and over again but never stays fired up. The boiler fires up and stays on for as long as I am running the hot water, so I have no issues for hot water. The only issue I have is what is stopping the boiler from remaining fired up for CH.
What else could the problem be other than the pcb?
Many thanks. Kiniun.
