i purchases a steam station a few months ago i hadn't used it for a while when i press the button to steam it won't steam could there be a blockage somewhere.
Yes possibly. Refer back to your instruction manual. You may be doing something wrong. Or if you use your iron quite a lot and use non ionised water it may be that you need to flush it with a descaler. Like I said refer back to your manual.
