Hi All

im at a loss with this boiler !!!
error code is 2 flashing green and solid red and solid red lock out. manual says lack of burner ignition,

ive changed the 2 electrodes right and left and the gas valve check power to the gas valve all fine , the boiler goes to fire pump runs fan runs and you hear it spark but no ignition just locks out , fiddled out with the wiring harness to the gas valve but pushing down on the 2 pins and it fired then switch tap off and back on locks out then fiddle about again stills locks out keep fiddling and pushing it fires !! now i got it to the point where i thought it was fixed few hours later same locks out ???? WTF ?

ive been on to biasi who are no help restored the gas valve to factory setting checked everything possible i can think of, the condensate does not have wires going to it.

Im thinking PCB but biasi said no chance ?

what you guys think ??
