polti 4-core cable connections?

Hi,
I've just replaced the 4-core flex between the hand-held iron and the base unit of my Polti Vaporetto 2400 steam generator iron, after the insulation on the original failed (from being bent too much?) at the hand-held iron end. When I switched on again, the hand-held iron heated up ok, with the red indicator light on the handle working, but nothing happened when I pressed the steam button; I couldn't hear the click of the solenoid/steam release. I had made a drawing of the connections/terminals at both ends of the 4-core cable before replacing it, but in case I made a mistake, would anyone be able to confirm the correct wiring connections?
Thank you.
