Sabre HE CH Boilwers.

[irenton]

I have a Sabre He CH boiler which I went for after a lot of research. It has worked well until recently when it has started locking out, usually on the hot water. My engineer, who is Corgi, has checked everything and can't pinpoint the fault as it wouldn't occur while he was here. Anyone with any suggestions?

Venturis require replacing on these too might be an idea to get yer man to replace it at the same time.

Someone will be along with the part number shortly I suspect.

If it's locking out to solid red light then its probally the primary thermistor 10027352 if it won't ignite and as a flashing green light then it could be the venturi 01005405.
