called to this boiler and found that it will go thro its start up procedure up to the point of pilot ignition but will not open main gas valve.
according to the fault finder in book you need to check 230 v at pin ML CONNECTIONS.
CANNOT FIND THIS , ANYBODY POINT ME IN THE RIGHT DIRECTION TA
it's on the ignition board which is attached onto the side of the gas valve. you undo the screw that holds in onto the valve and the cover should pull off allowing you to get into the wires which are on moldex plugs that can pull off. these wee boards are notorious for being faulty.
