Are you sure the gas valve is at fault as the pcb fails giving poor voltage to the gas valve, think its the green plug on pcb remove and fire up then test for 230 volts. (Ignor my advice if its not the wmb with the front green button switches)

Corgigazza-with solenoid connected to pcb(grey plug) boiler goes thro start up procedure but trips main rcd, disconnect solenoid from pcb boiler goes thro start up procedure but goes to lock out after 10 secs of spark.Will let you know if im wrong.Nige

Hi there, I've just discovered this site and can see myself using it for along time time to come.
This thread covers the same problem I've experienced with my Vaillant boiler and my query is basically where I could buy the spare regulator referenced - Vaillant part number NG 17-0376 ?
I tested my unit and traced the fault to this part which is down to earth. Also can anyone confirm that the regulator can be safely changed without disturbing the gas section of the gas valve.
Thanks for any help in advance.
Cheers, Jim
