2013 S4 825i power steering problem

I put away my 2013 gator S4 825i just like I always do: washed off, filled fuel, turned off key. Came back a week later and now the power steering doesnt work. Any idea what it could be? How can I check if the electronic power steering has power or isnt burned up?
It was working great when I put it away. The machine is driven very easy and only on smooth dirt roads.
Thanks for the help!
