Our sodastream does not work anymore. It’s the electrick model with three different gasfillings. When you put the waterbottle into the filling station and then you turn your suitably filled bottle down and you try to push some of those lights (- /--/ ---) for to fill your bottle, it sounds like little choked “puff” and then all lights are blinking (I think they tell mailfunction). No gas comes. I have changed new and stuffed gasbottle, power cable is its place and works. So what’s wrong? Thank You allready, Juha Heikkilä (Finland).
