Customer: 10 years
KevinWhiteJA :


KevinWhiteJA :

F4 in Glow worm 30sxi is ignition fault

Customer: I realise that I assumed you would tell me what to do
KevinWhiteJA :

yes that is what I was writing :)

Customer: Sorry this is my first time!
KevinWhiteJA :

No problem, I understand....this error is caused when the boiler tries to ignite and fails...the control will then shut the boiler .. you can try to top the pressure up by turning the tap slowly anti clockwise...and when the pressure will reach out around 2 bars then try to close it...this should reset the unit

KevinWhiteJA :

please let me know how it goes
