Ariston 27 RFFI boiler failing to ignite. Gas valve has been changed but no joy. Gas valve solenoid energised and ignition spark for about 8secs. then shutdown after three attempts. Any ideas? Possible board fault? Usual stuff with incorrect diagrams showing valve solenoid having two solenoids but only one of these is connected.
Probably this valve used in different combinations hence the error in the connections to the valve as shown in the diagram supplied.
