Error Codes
Error Code 010
Description – Mains voltage or 24V error during the cycle.
Possible Causes
A.) Power cord failure or disconnected.
B.) Sterilizer switched OFF during a cycle.
C.) Electric failure in the building system.
D.) 24 V power unit failure.
Checks and Actions
A.) Check the power cord is properly plugged. Check the power cord for electric continuity.
B.) Wait until the error phase on the screen is finished.
C.) (1.) Connect the sterilizer to a dedicated circuit as reported in the user instruction.
C.) (2.) Check the electric power in the building.
C.) (3.) Check the electric power at the wall plug.
D.) Check the 24 V power unit (see Test instructions service book).
Error Code 011
Description – Software error during update.
Possible Causes
Software update failure.
Checks and Actions
- Repeat the update.
- If the failure persist, call service.
Error Code 012
Description – Microprocess or error
Possible Causes
Bad communication with the mains load control microprocessor
Checks and Actions
- Update – reload the software.
- If the problem persists, replace the main board.
Error Code 020 to 043
Description – Internal voltage out of range.
Possible Causes
- Sensor failure.
- Main board failure.
Checks and Actions
Disconnect progressively all sensor cables from the main board. Check the ERRORS screen:
- If the error persists, replace the main board.
- If the error disappears, replace the sensor/cable that causes the error.

Error Code 050 to 051
Description – Mains voltage out of range.
Possible Causes
- Mains voltage out of range.
- Main board failure.
Checks and Actions
- Check the System Info screen.
- The mains voltage of the 230V sterilizer version must be between 180 and 264 volts and must be stable.
- The mains voltage of the 110V sterilizer version must be between 90 and 132 volts and must be stable.
- If the mains voltage is bad (out of range or unstable), check the mains supply voltage with a multimeter and compare it with the reading of the System Info screen.
- If the values are different, replace the main board, otherwise check the electric supply.

Error Code 060
Description – Low voltage on 24 VDC circuit.
Possible Causes
A.) Failure of a 24 V-supplied component or in its connection cable to the main board.
B.) Failure of the 24 V supply unit.
Checks and Actions
A.) Disconnect progressively all components from the main board. Check the ERRORS screen:
- If the error disappears, replace the component/cable that causes the error.
- If the error persists, see next step.
B.) Check the 24 V power unit (see Test instructions service book).
Error Code 061
Description – Too high voltage on 24 VDC circuit.
Possible Causes
Failure of the 24 V supply unit.
Checks and Actions
Check the 24 V power unit (see Test instructions service book).
Error Code 070
Description – 24 VDC overcurrent.
Possible Causes
A.) 24 V component failure.
B.) Sensor failure.
C.) Door locking motor failure.
Checks and Actions
A.) If the error is permanent disconnect progressively all 24V components/sensors cables from the main board.
Check the ERRORS screen:
- If the error disappears, replace the component/cable/sensor that causes the error.
- If the error persists, replace the main board.
B.) If the error is not permanent: If the problem persist see next step.
C.) See Test instructions service book, chapter SPECIFIC TEST FOR INDIVIDUAL COMPONENTS, Door locking system – automatic mode, Door locking system – manual mode.

Error Code 080, 083
Description – Main board temperature too high.
Possible Causes
A.) Main board failure.
B.) Room temperature too high. Condenser/Dust filter/Fan grid clogged/dirty.
Checks and Actions
A.) With a hand-held thermometer, check the temperature in the main board area. If the values are different from those measured by the sterilizer (check the System Info screen), replace the main board.
B.) Clean the component with compressed air.
