Hi all,

The heating element in my Bosch fan oven (model HBN7020GB/01) appears
to have gone and, foolishly, I thought it would take about 5mins to
replace (or at least take out and test), however...

Getting to the element is no problem - from inside the oven I simply
undid the four screws holding the fan cover to the back of the oven and
hey presto there was the fan and the element surrounding it (it's a
semi-circular element). The element itself is held in place by a pair
of screws at either end (which I removed without problem) plus a clip
in the centre. The problem is this central clip - the screw holding it
to the back of the oven is hidden by the fan. Simple, I thought;
remove the fan to get to it...but no...there's a reverse threaded nut
holding the fan in place but even with this removed it won't budge.
Does anybody know if I need to pull the oven out and attack it from the
rear? Or do I just need to use a bit of brute force and ignorance? I
don't really want to risk completely knackering the thing as the top,
non-fan, oven is still working and the wife will kill me if that stops
working too!

I tried calling the Bosch 'help' line but their only response was
'we can't tell you that, you need to call out a service
engineer'.

Any more useful help or advice gratefully received.

Mark.
