My Polti Model VT (Silver) has hardly ever been used and functioned perfectly when last used. Always emptied after use it still heats the water but will not eject steam, I suspect that the valve may be defective. If so, are these still available. Purchased February 04.

I had a similar problem with my Polti Eco 2000 steam cleaner. In my case it tuned out to be limescale that was blocking it. I bought a pack of "Kal-Stop" (got it on ebay) which seemed to clear the problem, and the machine has worked since. Might be worth a try.
