Just reported to 151 the fact that nothing has changed.
Explained that many others had same problem.
They told me I was the only one today with the problem !!
Engineer arranged for Thursday morning.
Devil's advocate position........................................
Are we the only 6 out of, say 500 installs, with the problem ?
Hence the reason we write in to this forum, whilst others aren't interested as they're OK !!
Just clutching at straws now !
