did you check the aps for proving

 

[Whn1]

Does it ignite? If not as above check aps first

 

[dancinplumba]

does this boiler even have an aps ?

 

[jefaz]

nope i dont think it does

 

[Hardy1]

force draught burner..no APS-psk &Whn1

 

[dancinplumba]

[SafeGasInstall]

u did check gas supply ?

 

[Hardy1]

E133-fault code(dancin plumba)... yep checked all gas pressures TT passed no drop.. 22mbar standing pressure at meter..21.5 mbar standing pressure at appliance literally less then a 2m run from gas meter.. any help guys?.. cheers again.

does it spark ?

 

[Hardy1]

nope no spark.. pump-fan. fan cuts off...i done a bit of research online and suming about spark electrodes are faulty..

e133 is no gas supply.
did you turn the gas meter valve back on

 

[Hardy1]

thought so was thinking spark gap or electrode.. ill get back to it..cheers dancin plumba.

 

[Hardy1]

e133 is no gas supply.
did you turn the gas meter valve back on

yes the valve is open..as i got a standing pressure at the gas valve inlet test point.

check the correct polarity

 

[Hardy1]

checked..the boiler was installed 2 years ago..been working fine since...cheers.

have you turn the selector knob to reset on the boiler

 

[jtsplumbing]

Is gas valve opening ? is fan running at full speed ? may come down to PCB !

 

[southcoastboile]

is the burner firing? no gas fault code, poss fsp

 

[hydrotherm]

check gap between spark electrodes
