Hi Again. I just learned to NOT put single quotes in your post. :-) Im having the same problem. I followed the directions in the tech document. (A link is at the bottom.) Turned out that the black fill tube was clogged with ice. It should be pliable. If you cant easily squeeze it together, clean it out.
Hope this helps.
