inherent fault my a##. take a screw driver and fix the problem yourself. It's the cheapest way...
The pressure control switch on the iron (presumably this is what you meant) is made of cheap plastic and it probably broke.
Get a screw driver, open iron cover and stick a nail about where the plastic hinges of the button supposed to be. The original retaining mechanism (ie the top handle holding the hinges) will hold the nail in place and the button will work again.
I have a problem with the combi-hose. At the base, as far as I can tell the cables worn out. If I can't find the spares, I'll trim the cable/hose and make like new... simples ;)
