My IGT S+ slot machine is displaying an error, what does it mean?

Do you have an IGT S+ slot machine with an error code that you cannot clear?

We have helped customers all around the world clear their error codes.
Many times when the display on the door indicates an error condition, open and close the door to reset the game and clear the error. Open the main door which clears the current game information and a "0" appears in the Coins Played window. Closing the door resets the game and the reels will spin and stop in their last valid position. The error code should clear and the digital display returns to normal game play. If the problem still exists or quickly reoccurs, use the information below to correct the problem.
