Another old boiler where the themostat kicksin the motors start but the flames don't light.
At onepoint we could turn down the heating to get hot water but now we just get the motors but not the flame.
fault on these boilers is the main gas solenoid fails part no 17 0365.this also blows the resistor on the board part no 13 0391.total cost of around £200.There should be 200vdc from the board to the gas valve(grey plug).
