Mend Ravenheat RSF84ET Boiler Heating Replaced

Ravenheat RSF84ET combi boiler, what's wrong with it??

Hi, no heating or h.w. Corgi plumber replaced 'gasvalve pcb' and 'main pcb' yesterday, got it working, but it packed up after 4hrs, making strange noises. Today plumber replaced 'HT lead' and 'spark igniter' but still no joy. Huge bill to pay but still no heating or h.w.! Plumber described problem as "boiler lights but does not stay lit and continues to try and ignite".
Can anyone help please? Thank you...

Sorry, forget the strange noises, apparently it was just the sound of the boiler trying to ignite.
