I have a Vokera 24 Linea, hot water no issues, but intermittent CH.
If turning heating on, it will eventually fire up, (maybe after 1-2hrs), and will stay on with no issue until CH off for a period of time.
Then, when starting from cold, back to a 1 hr delay.
All the basics like pressure etc ok.
Had the diverter valve out and cleaned, no result.
When CH is switched on, I can hear the gas valve opening, but it never fires up.
Possible ignition PCB?
Also, maybe unrelated, getting intermittent and random CO error message, and boiler fires up of it's own accord into Combustion mode, even when set to HW only.
Have checked the combustion button which is not damaged nor pressed in. Has been reset but this issue still occurring.
Any help appreciated, thanks
