If you have been using tap water in your iron, and your water has lime or calcium in it, then the iron is probably clogged up. You might try using a product like "Lime Away". Read the warnings on the bottle first. Don't get it on your skin or in your eyes. Don't breathe the mist or steam. The bottle I looked at also had warnings about how it would mess up some counter tops or sinks.But if the iron doesn't work anyway, carefully pour some into your iron maybe about one fourth full, then carefully shake the iron to get the stuff all over the insides of the iron holding the iron like you would if you were ironing. Let the iron sit for a bit, then shake it again, maybe a couple more times like that. pour it out into an old bowl that it wont ruin, and see if there are a lot of minerals in the liquid. If there are, that may have cleaned it enough to start working again. Pour enough water in the iron until it is half full, plug it in and turn the temperature up to where it will produce steam, but don't iron any clothes yet because there is still cleaner in the iron. turn the iron so it is like you are ironing, but don't let it touch anything. Hold it over something like some old rags. If steam comes out, don't breathe it, but let it come out for a little while. Pour out that water and refill with fresh water and let it steam over the rags again. Pour that water out and all the chemicals should be flushed out of the iron. Carefully wipe the hot plate off to get any chemicals off the plate. Good Luck
