@Fritz I managed to finish the game. The pot also returns to my inventory but go to the plug and the turn the crank clockwise (to the left), you need to to hold the crank and then turn it, if you hear the sound but it didn't turn, go out from the place and then try to do it again.

 "Time to Escape"){kind=icon}
Thank you very much. I will try harder.
