Hi,
My Worcestershire Bosch Greenstar 24Ri is still shutting itself off occasionally.
Y plan, micro bore.
Restarts immediately with a reset & after 4 WB visits still no joy.
But... This is clutching at straws now...
I heard about cross bonding & the WB manual says "all pipes must be cross bonded".
However I can't see any sign - I presume the clamps would be close to the boiler.
With the boiler casing earthed via it's supply connections &
with all the pipes coming to/from the boiler on a metal frame as part of the boiler surely this forms the cross-bonding?
Is it that the earth via the mains connection is not sufficient?
Can't think why WB haven't spotted this if this is the case, oh and i did use a corgi installer of course.
I mostly suspect (having removed one radiator for decorating) that
the original powerflush wasn't thorough enough.
Although the radiators & hot water seem fine in practice.
Anyway if the air temperature rises next week end I intend draining/hosing all radiators/restorer and refilling.
So hopefully that's the real problem - just thought I'd ask so i'd be ready for the next WB visit.
Thanks
