Incident Possible causes What you can do
103 The sterile filter is soiled/blocked. 1. Check whether the sterile filter suction
aperture (centre aperture) on the rear panel
of the steam sterilizer is blocked. If yes,
replace the sterile filter.
2. If nothing can be recognized, remove the
sterile filter on the rear panel of the steam
sterilizer and perform a program run without
a load. If the program has been ended
successfully, the sterile filter is blocked. In
this case, replace the sterile filter.
104 see event 103
110 a) The steam sterilizer is overloaded or the
load has been arranged badly.
b) The mains voltage is too low, poor
building voltage supply (e.g. undersized
installation, defective socket, multiple
devices on a single socket/fuse).
a) Comply with the maximum permissible
load quantities (see Loading the steam
sterilizer [}page21]). Ensure that the load
does not come into direct contact with or
covers the steam injection nozzles.
b) Check the building-side socket / test the
steam sterilizer using a different socket or
circuit.
111 see event 110
113 a) The steam sterilizer was switched off at
the power switch during a program run.
b) The power plug has been disconnected or
has not been connected correctly in the
socket.
c) Power outage in the building supply or the
building-side RCD switch has tripped.
a) Never switch off the steam sterilizer at the
power switch during a program run.
b) Check whether the power plug is
connected, the power cable has suffered
damage or a loose contact or loose plug
connections is the cause. Plug the power
plug back into the mains socket.
c) Arrange for an inspection of the building-
side installation (e.g. automatic circuit
breaker) and test the steam sterilizer at
another socket or on another circuit.
114 see event 78
124 a) The surrounding temperature of the steam
sterilizer is too hot.
b) The minimum clearance to the
surrounding surfaces has not been
maintained. The steam sterilizer receives no
or insufficient cooling air.
c) The steam sterilizer is overloaded.
d) The steam sterilizer was operated without
an insert rack and the load (especially the
textiles) comes into direct contact with the
chamber wall.
e) The openings for suction of the cooling air
on the underside of the steam sterilizer are
covered.
f) The chamber filter “Vacuum” is soiled/
blocked.
a) The ambient temperature must be below
40 °C. We recommend a maximum
temperature of 25 °C.
b) Maintain a minimum clearance to the
surrounding surfaces (see information in the
technical manual).
c) Comply with the maximum permissible
load quantities (see Selecting the program
[}page25]). If necessary, perform a vacuum
test.
d) Always operate the steam sterilizer with
an insert rack and comply with the loading
information (see Loading the steam sterilizer
[}page21]).
e) Check whether the cooling air suction
openings in the underside of the steam
sterilizer are covered and remove any
objects obscuring them e.g. paper or
packaging.
f) Remove the "Vacuum” chamber filter (in
the rear area of the sterilization chamber
below) and check whether it is e.g. soiled/
blocked by packaging. If necessary, clean
the chamber filter.
