How can I fix Delonghi Magnifica ESAM3500.S?

Removable internal grinder has jammed in machine on an angle so I can't reach squeeze button to remove. It is at full length from the bottom attachment with the middle section raised to full height off to the right hand side in the machine cavity and won't come down so I can remove. How do I get the expandable pipe sleeve part of this to move down over the internal pipe section reducing the height so I can take the whole unit out?
