Hi All
Hoping someone can help.....
I inherited a S/H Vaillant as above when I bought an old house here in Spain.
It is LPG gas.
It will spark on ignition but will not fire because no gas is coming through!
I have fitted a new gas valve, part number as per Vaillant and since fitted a new PCB as it looked suspect.
Still no gas. Have 19 mbar at inlet of valve.
I have correct resistance at both solenoids and have 230 volts at two pin postions on the gas valve plug and can hear the solenoids buzz when I put a screwdriver to them and to my ear.
Can anyone suggest any reason why I might not have gas?
Thanks in advance
Cheers
Goatherd
