There is a second Torx screw under the 2 steam jet buttons and just in front of these is the steam control valve that also needs to be removed (push it down and towards the 2 steam buttons)
To remove the Steam buttons use a small blunt screwdriver and ease the thin end in to release the capture hook that holds them in place
After this you can remove the top section of the handle to get at the last (of 3) screw that hold the handle on to the tank and plate ... good luck
