12 Troubleshooting
The program control is equipped with a sophisticated error management system. If
an error occurs during program execution, an error message is shown in the cycle
display (16) or the current values display (13).
If an error occurs:
♦
Memorize or write down the error message.
♦
Press the START/STOP key (19).
This will interrupt the program cycle. The sterilizer is returned to a safe state.
