OK, I found them, on first glance at panel 301 there appears to be only a few of fuses, which I initially checked.
After finding the drawing (attached) showing fuse location, there are 6 fuses hidden between the relays!
(It appears I have more fuses than the drawing shows anyway!)
The way that you stand at the panel, and the way the panel hinges, you cannot see them.
You have to get your head right down and be straight on to the board. The first picture makes it look so obvious but it's not!
Anyway, this might help someone one day! Or at least jog someones memory when looking for fuses!
