Hi, I've got a Worcester Bosch 24 CDi RSF that will not light. It sparks, a very small flame appears but doesn't light fully then after about 5 seconds goes out and goes into boiler lockout mode indicated by a slow flashing CH red light. Both the PCB and gas valve have been replaced and I'm getting correct voltages to the valve solenoids and regulator and continuity on all three.
Any help would be gratefully appreciated.
Cheers, tom.
