Hi, came home on friday night to find the boiler won't ignite. there is a spark as far as i can see through the view hole. we have had the pcb replaced following the watchdog thing regarding overheat lockouts so we now have the replacement kit pcb. following trying to light 5 times, the boiler locksout and the red light flashes every second. we know it's not the fan because that's new. all the wires have been checked for continuity.
we definately have gas cos the cooker is working. the pcb is only 7 months old and the boiler is ten years old. any ideas would be much appreciated. thanks
