Alright guys?
The above boiler is going to fault light 15 seconds after putting a demand on. Doesn't spark or anything, red light comes on solid and the yellow light flashes twice, MI's suggest a fault with the gas valve or PCB. Checked resistance of the gas valve coils, they are spot on. Checked continuity down gas valve lead, which was fine. So MI's say faulty PCB.
Replaced PCB but the exact same fault is there. Baxi tech just advised to order new gas valve and lead, but I would have thought that it would still spark, even if the gas valve was knackered?
I also checked the thermostat and potentiometer resistances, which were all spot on also.
Anyone had this issue before? Or offer any advice? Cheers!
