Error messages ______________________________________________________

Error messages generally occur with the display message «Error», followed by the error number and a description

of the error.

Error messages can appear before a program is started: i.e., as soon as the power switch is placed on, or some

time after the power is switched on. Or, they can occur after program start, while the program is running. If errors

occur while the program is running, the system will always issue an error message, and it will abort the program.

Depending on the chamber pressure at the time that the error appears, the system may stop the program immedi-

ately and may automatically release the pressure in the chamber. Or, it may stop the program together with ventila-

tion of the chamber. During abort of the program, the display will alternate between the error message and the

program phase («Pressure release» or «Ventilation»). After the program has been stopped, the display will alternate

between the error message and the message «Acknowledge with button ‘–'» and «Stop / End». When you press

button «–» this will delete the error message (unless the cause of the error remains, in which case the error mes-

sage will also remain). The door of the autoclave will remain locked until you have acknowledged the error mes-

sage.

If a program is aborted, the items loaded in the autoclave must be considered non-sterile or not disinfected. The

sterilization or the disinfection program must be repeated. In such cases, we recommend that the user remove all

items from the chamber after such an abort, and to run one sterilization cycle without a load. This is because the

drying phase may not proceed properly after the first start.

If an external printer is connected, and if you have set the immediate-printout option for the printer to «Yes», the

system will automatically print out a log at the end of the program abort. This will take place not only for non-cyclic

errors (i.e., a program has not started), but also for cyclic errors (i.e., during a program). The printed log will show

the complete error designation. If the program is aborted before the end of the sterilization phase, the printout will

also show the message «Load not sterile».

The following tables show the error messages, their causes, and the corrective action:

Cause of trouble / Corrective action



The monitoring time was exceeded for achieving the sub-

atmospheric pressures for the individual evacuation pulses, for

the pressure release, and for the achieving of minimum

pressure for drying. Corrective action:

 Check the door gasket and the sealing surface of the

chamber for defects and for soiling. If dirty, clean.

 Check to make sure that the autoclave has been correctly

set up (see Section 2.3).

 Check to make sure that fallen instruments, filter paper, or

the like have not clogged the condensate return flow on the

bottom of the chamber.

 Determine the leak rate by running the program «Vacuum

test».

If this error repeatedly occurs, please notify your specialist dealer.



The monitoring time was exceeded for the heat-up phases for

the sub-atmospheric pulsing, and for reaching the sterilization

pressure. Corrective action:

 There may be too many items loaded into the autoclave for

sterilization. Reduce the amount loaded.

 If the mains voltage is too low, the heating output of the

autoclave may be insufficient. Check the electrical building

installation in the building. Try the autoclave on another,

more powerful circuit.

If this error repeatedly occurs, please notify your specialist dealer.



The monitoring time was exceeded for the pressure release.

Corrective action:

 Check the pressure-release fittings at the bottom rear of the

sterilization chamber. Clean them out if they are clogged.

If this error repeatedly occurs, please notify your specialist dealer.
