M9/M11 Sterilizer Error Code Explanation
If an electronic malfunction is detected during a cycle, a numeric error code will appear on the display panel. Each digit in the error code provides information about the problem that occurred.
To prevent risk of shock always disconnect power before removing covers or performing any service procedure.
Some procedures require power to be connected with covers removed. Line voltage is present. Use extreme caution to prevent electric shock.
Example:
First Digit = Where
The first digit indicates the component or system where the problem occurred. (example: 3 = Door Switch)
Second Digit = What
The second digit indicates what problem or symptom was detected. (example: 8 = Open)
Third Digit = When
The third digit indicates when the problem was detected. (example: 2 = Fill Mode)
