Glow Worm Swiftflow 80

Maintains pilot, (SIT gas valve) - fan runs but vibrates, could do with changing, no voltage to pump, therefore boiler will not fire on heating or hot water. how does this boiler provide flue proving - cant see an air pressure switch anywhere.

Any ideas guys?

if the fan isnt running properly the chamber fills up and starves the pilot/burner of oxygen and so fails safe and that is why it doesn't have an air switch
change fan and all should work ok

The fan is probably just covered in dirt.

Washing the impeller under a mains tap will usually make it as sweet as new.

I cannot make any comment on pump not running. Faulty pump or failed PCB? You need to test it!

Thanks for putting your CORGi so we can give you correct advice without hesitating. Pity some others dont do that!
