Had to get the Vaillant guys in. They changed the fan/motor and it now works. Goodbye £275.
Still interested in the elctronic manuals if anyone has them.
Has anyone got electronic versions of user and/or servicing manuals for the Vaillant VCW GB 242E combi boiler.
I have hot water but no heating (picked a super time to decide not to deliver any heating with 12 inches of snow on the ground!!) and want to see if there is anything I can do to...
