By "washing machen," I'm going to assume you're trying to say, "washing machine" -- and that's problem number one there. Everyone knows that electronics and water don't mesh well. More than likely you've permanently damaged your iPod.
Please elaborate on your situation more. What does the iPod do, exactly? What displays on the screen when you turn it on (assuming, of course, that you let it dry out completely [~1 to 2 weeks]) before trying to use it?
