Hi,
I'm hoping someone can help?

We have a Raveheat HE85T combi boiler, approx 3 - 4 years old. Recently, for some reason unknown, the central heating is no longer working(we've checked the pressure and ignition, and pressed the reset button too!), despite this the hot water is working fine?

Can any of you advise a solution? it's getting cold, and I'm terrified of our pipes freezing up!

Thanks in advance

Marcella

Managed to find the fault.
Despite the clock being on, it has turned faulty.
My husband (who is an electrican) tested the power at where the boiler timer connects to on the circuit board (orange cables) (connecting the circuit effectively bypassing the boiler timer switch) and the central heating fired up.
Good luck

We have just got the same problem. If the PCB needs replacing this will be the 4th in 3 years. Absolute rubbish!

external control not calling for heat
try to bridge roomstat link and timer switch link that may be stopping heating to come on and finally it it does not work than will be last thing PCB
