My 76aw hasnt got reset button?

Oh yes it does have a reset button. (well, it's nearly panto season)

here's the service manual:

Look at Exploded View 4. Part 515 is the cover, part 228 is the reset.

Believe it or not, that manual was the very first Gooogle search result when I looked for "76aw reset button". Surprised you missed it.
