PROBLEM
POSSIBLE CAUSE
SOLUTIONS
When starting a cycle, the chamber door locks
but re-opens immediately. The “Open the
door” message appears.
Door seal not properly placed; seal sticking out
Ensure that the door seal is evenly inserted on the entire circumference.
Door jammed by external objects or by the load itself
Remove any objects interfering with the chamber door. Check the door does not
force against the load or the chamber furniture.
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 ANNEX 7 for water quality
requirements).
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 into “Sleep mode”
immediately after opening the chamber door.
The chamber door has not been opened after the
previous cycle had finished and the “Sleep mode
delay” has expired
Press the SLEEP MODE button to exit”.
At the end of the cycle the display reads
“Open the door” but opening the door is
impossible.
The chamber is in vacuum due to an internal
malfunction
Switch the sterilizer OFF: this releases any internal pressures allowing the
chamber door to be opened. Call technical service if the problem persists.
The bacteriological filter is blocked
Remove the bacteriological filter to get the pressure released. Replace the filter.
Note that bacteriological filters need to be replaced every 400 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, call technical
service.
Warning about USB saving (HTML and SCL
files)
The USB mass storage 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 seal, dust filter,
bacteriological filter…). See “Maintenance” chapter.
Before sending the sterilizer for technical service, remove the mains cable, empty both water tanks and use the original or appropriate packaging.
