Hi can you let us know please, are you on LPG or Natural Gas.

Can you give us the model of your biasi.

Is it just hot water that is not working, or heating and hot water.

Hi Brian
Thanks for your reply. We use natural gas. I found a little sticker saying M90E24S GB N061060605 - is this the model? The boiler is not firing up if you open hot water or switch the heating on or use both.

Ok natural gas,
No that's probably a serial number of some kind, I will see if I can find the model from it.
By the sound of it, its not going to be a simple fix.
Is the fan running. If it is you will need to pull the front off the boiler and check the pressure switch. You can do this with a multimeter and by gently blowing down the pipe to see if you get continuity on your meter.
That's the first step really.
Are there any lights flashing or numbers on the front Lcd panel if it has one that will give us a clue regarding the fault.?
