Analysis and resolution of problems
If your sterilizer is not working correctly, please consult this list before calling the Technical Service Department:
The sterilizer does not
power-on.
The power cord is not plugged-in.
There is no voltage at the socket.
Check the cause for the lack of voltage at the socket
and fix it.
The main switch and/or differential
switch are OFF.
The mains fuses are blown.
Replace with good fuses of equal nominal value.
(See the Summary Table in Appendix A, Technical
Characteristics).
After pressing S TA RT ,
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 approx. 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 least, until the MI N level signal turns
off).
