APPENDIX D – GENERAL PROBLEMS
INTRODUCTION
If you run into a problem or alarm while using the device, you should not be immediately concerned.
It may not, in fact, be related to a breakdown but, more probably to an anomalous situation, often merely transitory (such as
a blackout), or incorrect use.
In any case, it is important to first identify the cause of the anomaly and then take suitable corrective action, either
autonomously or with the help of the Technical Support Department (see Appendix Z).
For this purpose, below, we provide instructions for diagnosing and resolving general problems, in addition to a precise
description of the alarm codes, their meaning and their solution.
ANALYSIS AND RESOLUTION OF PROBLEMS
If your sterilizer is not working correctly, please make the following checks before calling the Technical Support Department:
PROBLEM POSSIBLE CAUSE PROPOSED SOLUTION
The power cord is not plugged-in. Plug it in.
There is no voltage at the socket.
Check the cause of the lack of voltage at and socket
and fix it.
The main switch and/or differential
switch are OFF.
Turn the switch ON.
The sterilizer does not
power-on.
The mains fuses are blown.
Replace with good fuses of equal nominal value.
(See the Summary Table in Appendix A, Technical
Characteristics).
After pressing START,
the sterilization cycle
does not start.
The device is preheating.
Wait for the sterilizer to reach the proper operating
conditions for starting the program.
NOTE: Under normal conditions, the average
preheating time is about 10-15 minutes.
The MIN water level
icon is lit. The distilled water level inside the
tank is below the minimum level.
Fill the distilled water tank until the MAX level indicator
comes on (or, at any rate, until the MIN level signal
turns off).
The alarm icon is lit.
An alarm was triggered, with the
generation of the relative code and
message (see LCD).
Check the alarm code and take the appropriate action.
(See the following paragraphs, Alarms, Alarm Codes
and Troubleshooting).
The safety valve has
intervened.
Locking ring loosened.
Presence of anomalous
overpressure in the chamber.
Check that the knurled locking ring is correctly
tightened on the upper part of the safety valve.
DANGER
LET THE DEVICE COOL, OR WEAR
GLOVES TO AVOID BEING BURNED
WHEN TOUCHING THE VALVE.
There is residual pressure
remaining in the sterilization
chamber at the end of the cycle.
NOTE: the display shows:
NOW LEVELLING
PLEASE WAIT…
Wait several minutes, until the pressure returns to 0.00
bar, and try to open the door again.
Check if the bacteriological filter is clogged and, if
necessary, replace it with a new one.
The procedure for storing the ambient temperature
(SET 0 bar function) was not executed correctly.
Contact the Technical Support Department (see
Appendix Z)
At the end of the
program (CYCLE
COMPLETE), I'm not
able to open the door.
At the end of the cycle, the safety
door lock remains on.
Contact the Technical Support Department (see
Appendix Z).
