Incident Possible causes What you can do
408 a) The water inflow tap has not been opened
or has been opened only insufficiently.
b) The cold water inflow hose is kinked.
c) The water supply in the practice is
interrupted.
a) Open the water inflow tap completely and
check the central water inflow tap.
b) Check the installation of the waste water
hose. It must be installed without kinking and
may not be crushed.
c) Check the shut-off valve for the domestic
water connection.
If a leakage water detector (water stop) is
installed:
d) The leakage water detector is without
function.
e) The inflow filter in the leakage water
detector is blocked by soiling in the building
supply.
d) Unplug the leakage water detector control
device, wait approx. 30 s and plug it back in
again. A switching noise on the water inflow
tap (black box on the water inflow tap) must
be audible.
e) Clean the inflow filter in the leakage water
detector valve as follows:
1. Close the water inflow tap and start a
vacuum test.
2. Wait until the device displays a
malfunction message and then switch it off.
3. Unscrew the leakage water detector valve
on the water inflow tap and check the inflow
filter; clean it if necessary.

ready for operation. Should this repeat,
please contact the service technician.
438 The steam sterilizer must be validated. Arrange for validation of the steam sterilizer.
439 see event 102/131 a) Check the installation of the outlet hose.
This must be installed without kinking or
sagging and at a constant decline.
b) Check whether the building siphon or the
waste water line is are blocked.
c) If multiple devices are operated
simultaneously, we recommend the
installation of an additional siphon.
d) Remove the "Pressure release" chamber
filter and check whether it is soiled/blocked
by packaging. If necessary, clean the
chamber filter.
