Malfunction messages
Event Possible causes What you can do
F02 The steam sterilizer is overloaded. Comply with the maximum permissible load quantities, see
Selecting the program [}page33].
The door does not close tightly, possibly the
door gasket is soiled or worn.
1. Check whether the door gasket is soiled or worn.
2. Clean or, if necessary, replace the door gasket, see
Replacing the door gasket [}page50].
The steam generator is overheated. Switch off the steam sterilizer and allow it to cool for
approx. 15min.
Insufficient mains voltage. The on-site power
supply is poor (e.g. undersized installation,
defective socket, multiple devices on a
single socket/fuse) so that the steam
generator cannot heat up.
Check the building-side socket or test the steam sterilizer
using a different socket or circuit.
F04 The sieve tray in the sterilization chamber is
soiled.
Remove the sieve tray from the sterilization chamber,
clean it and replace it, see Sieve tray of the sterilization
chamber [}page49].
The outlet hose is kinked or crushed. Check the hose for kinks and crushing.
F08 The internal device time monitoring is
defective.
Check the building-side socket / test the steam sterilizer
using a different socket or circuit or connect to a mains
filter. Upon repeated incidence, arrange for an electrician
to check the electricity supply for electromagnetic
disruption.
