I've noticed we seem to use it more for convection than microwaves and
have never used the grill. What about you?

It's a shame that only the back has the self-cleaning surface or is
that because of the microwaves?

Steam coming out of a microwave oven is fine - after all they're not
airtight and you wouldn't want a pressure build-up while you were boiling
something.

I hadn't thought about the pressure build up, that's a good point.
Thanks for the reassurance. Strange it should come from the bottom
though, not the top.
