I have had problems too, with leaking. The instructions do say not to use distilled, I get well water that is good (not from my house ,too much iron!) Does anyone know why distilled would cause the leaking (someone wrote that here)? I now just use a spray bottle also but it's not as good really as steam from the iron.
Another issue I have is that most of the time the iron will not turn itself back on when it goes into "hibernation mode". I've had this problem with several of them. Anyone else?
