I need help to fix my Sime Friendly Format 80E. It starts up and runs for 10 seconds before stopping completely. After a minute or so it then repeats the process.

This results in water or radiators not getting hot.

Think it's to do with the lockout being kicked in but not sure why this would be. Thoughts?
