Woke up to a New Yr boiler problem this morning
Have a 12-13 yr old Vaillant 828 TurboMAX, in that time it's had a diverter valve change, air pressure switch change & timer clock change.
This morning I have the green light flashing, no warning / lock out light (red light) & the amber light isn't coming on either. Digital display is working fine
No hot water or central heating at all. No error codes showing either.
Any ideas at all? I'm thinking maybe the air pressure switch is gone again?
