Problem

Possible cause

Solutions

When the sterilizer is connected
to an automated water supply
system: there is no clean water in
the tank, but the automatic water
filling does not fill the water.

Water fill system not connected.

Connect the water fill system to the sterilizer. See "Water quality" on page 93

When the water fill system attempted to fill the
tank, water was temporarily unavailable.

Since water tank filling is attempted only once in-between cycle execution, this event
inhibits water feeding. Switch the sterilizer OFF and then ON again.
Check the external water supply system.
Check for water leaks from the sterilizer.

Faulty MIN water level sensor in the clean water
tank.

Call service.

The sterilizer enters the standby
mode immediately after opening
the chamber door.

The chamber door has not been opened after the
previous cycle had finished and the standby mode
delay has expired.

Press the standby button to exit.

At the end of the cycle the
display reads “Open the door” but
opening the door is impossible.

The HEPA filter is clogged.

See “"Emergency door opening" on the next page”.
Contact technical service if the problem persists.
Remove the HEPA filter to get the pressure released. Replace the filter.

Note

: The HEPA filters need to be replaced every 1200 cycles.

The sterilization process phase of
a sterilization cycle was longer
than expected.

The chamber temperature dropped below the
minimum threshold and the software performed a
successful recovery.

Wait for cycle completion. If the problem occurs frequently, contact technical service.

Warning about USB saving (HTML
and SCL files).

The USB pen drive is not connected or not properly
connected to the sterilizer.

Check presence and connection of the USB pen drive.
If the problem persist, call service.

Warning about programmed
maintenance.

A component shall be replaced for the programmed
maintenance of the sterilizer.

Call service to order the requested component (door gasket, HEPA filter…).
See "User maintenance" on page 58
