Hi guys,
called out to repair this boiler, would not ignite fault code LF- fault finding pointed to new PCB. Changed PCB (there are 2 grey wires in a terminal block cannot find home for - don't know if this is the problem) but same problem - will not ignite. There is 200v DC at gas valve and all other ignition sequence takes place. Really could do with picking your brains please!!!!!!!!!!!!
