The Electronics module is the same as the Pott. Profile boilers.

Ok, so another avenue for a spare ;-)

One low tech possibility is that as soon as the main gas lights the pilot
flame is diverted a little and the flame failure immediately stops the
main gas valve.

I was looking at that carefully as it lights and indeed considered it
a possibility but as the replacement module seems to have cured the
problem (fingers still crossed) I guess it couldn't have been that
(unless it was marginal and the replacement module is less 'touchy')?

All the best ..
