my iron and is not giving off steam ironing normally only see steam when I click the button. I put iron at maximum and i press the third button of the boiler (the most powerful), but i can not see any steam. Is hard to remove wrinkles from clothes, I can only press the button iron. Photos and videos show the steam escaping from the iron without pushing the button. I think maybe somethig is wrong with my iron, do you confirm it?
