Can you confirm the gas is still on?

Has anything been turned off under the boiler?

Customer: replied 8 months ago.
Nothing has been touched ! gas is on and all ok - one minute I was using hot water the next minute everything stopped and the symbol F28 came up!.
Expert:  Andrew Smith replied 8 months ago.

ok, do you have the full model details?

Customer: replied 8 months ago.
On the front of the Glow-worm book they gave me is: Installation manual for Air/flue gas system for ENERGY, SUSTAIN, HOME, ULTIMATE, EASICOM, ESSENTIAL

Also on the front of the boiler is GLO WORM - 25c if that is any help!.
Expert:  Andrew Smith replied 8 months ago.

25c, ok is there anything else written on the boiler?

Customer: replied 8 months ago.
No nothing !!
Expert:  Andrew Smith replied 8 months ago.

ok, it could be anything to do with the gas, or anything to do with the ignition.

It is failing to light.

With it only being in for 4 weeks the manufacturer will come out free of charge tomorrow if you ring them in the morning, but without a multimeter and standing in front of it there is not much else i can do.

Expert:  Andrew Smith replied 8 months ago.

It could be a loose connection inside the boiler preventing it sparking, or it could be a faulty part

Expert:  Andrew Smith replied 8 months ago.

Sorry

Man has just been - he said the gas wasn't firing up strongly enough !!
Expert:  Andrew Smith replied 8 months ago.

Was he an expert?

Did he check the gas pressure to the gas valve or the burner?
