Glow-worm Betacom 30 Fault codes & diagnostics

No fault code table in its manual

We've read the Glow-worm Betacom 30 manual we hold, and it has no fault code table, so there are no codes to list. We don't fill the gap with codes from a similar boiler, because the same code can mean something different on another model. The fault code table in the installation manual is the one to trust.
