Need help in cistern entrance

[Googolplex]

Hello.
I already played the game one time but now, I wanted to play it again.

Now, I have a problem in the steering room (or control room, or whatever it in english called). To repair the bridges in the cistern entrance.

So, there are the stucked wheels. I think that was normal.
But there are stucked levers too on both sides.

First, there was only one side in which the levers have stuck. And now the levers on the other side stucked too.

There is nothing what I can do.


Please help.
