no, its not the Aquaspeed 170, but Aquaspeed 150. i succeded to unwrap the housing, but did fail in disconnecting or dismounting the power cord terminal.i could not disassemble the Iron to reach the heater. to dismantle, step 1 unscrew 3 visible screws. step 2 lift the heel cover away, by unsnapping 1 hooks at the right and one at the left side of the heel cover. i used thumnbnail to deform the heel cover for not to wear out the snap-in hooks. step 3 remove the dischalk stick (don't know the right wording in english) step 4 lift the top cover (which covers the spray jet part), 2 hooks at both left and right, use thumbnail or flat screwdriver, start at the top hook. step 5 take off the spray and steam buttons, 1 hook at the front side, 1 hook at the outer back side step 6 take off 2 screws: one keeps the upper half of the handle, the other fixes the water container at the heater plate. Attention: when unmounting the container, and turning the iron upside down, a small (4mm diam, ~10 mm length) silicone cylinder part will fall out, some kind of actor of a bimetal thermo switch in the ground plate, which probably controls water flow (not the electric thermostate) so far so good, i got my problem solved, but would like to know how to disassemble the container from the ground plate and how to replace the cable?

I had the same problem. Turned out to be dirty contacts on the thermostat, easily cured with a strip of sandpaper, but you need to dismantle the iron first.

• Remove the 3 Torq screws in the heel plate (the purple triangular bit at the back, that you stand the iron up on when it's cooling off). One of the screws is a security screw so you'll need a special screwdriver, though I suppose you could risk drilling it out if you're desperate.
• Prise off the bottom section of the heel plate, to reveal the cable connector block. Pull out the connector block (it's just a push fit).
• Pull out the self clean / steam selector button.
• Prise off the white plastic front cover (the one under the self clean button, that surrounds the jet spray nozzle).
• Under the cover are 3 screws that hold the sole plate and iron body together. Undo them.
  
• Now you should be able to separate the main components of the iron and get to the thermostat. Check the contacts - mine had a build-up of carbon from the arcing as the thermostat operates. Clean both faces with a strip of sandpaper, then reassemble the iron, being careful to align the temperature selection lever correctly.
