10. Display Error codes

If an error occurs, the error code is displayed in the main loop. All windows, however, can still be accessed by pressing
the button. If the button is not pressed for approx. 4 min, the error code is automatically displayed again. The error mes-
sage disappears automatically as soon as the source of the error is corrected. All errors that exist for longer than 6 min,
are saved in the error memory.
