Problem Cause and remedy
Fault518-521
No flow was detected when dispensing from an external
supply container.
Caution when handling chemical agents.
For all chemical agents, the chemical agent
manufacturer's safety instructions as given on their
safety data sheets must be observed.
Check the level in the containers and replace empty
ones with filled ones.
Check the suction apertures of the container lances and
remove any deposits.
Check the hose connections on the container lances,
the washer-disinfector and any DOS modules.
Remove any kinks from the dispenser hoses and check
the hoses for leaks. Position the dispenser hoses so
that they cannot kink.
Vent the dispensing systems.
If you identify any leaks in the dispenser hoses or defects
on the container lances, contact Miele Service.
Fault 550 The waterproof system has been activated. One of the
water supply hoses might have a leak.
Close the stopcocks.
Contact the Miele Customer Service Department.
Fault555 Too much water has accumulated in the steam condenser.
Wash water may have been diverted behind the protective
panel of the steam condenser on the back wall of the wash
cabinet because of angled load items or injector nozzles.
When installing angled injector nozzles and sorting load
items, ensure that the wash water outlets point towards
the centre of the wash cabinet.
Restart the cleaning machine. Excess water is pumped
out automatically.
Fault559 There is a problem with the process documentation
interface. The machine has detected a module for an
Ethernet interface, but only a serial interface (RS232) is
activated in the controls.
Deactivate the RS232 interface:
Open the menu for configuring the interface Further
settings/Interface and then select Ethernet.
Wait approx. 90seconds. The Ethernet module XKM
3000 L Med needs this time for initialisation. It may be
necessary to reconfigure the interface.
Or
Replace the Ethernet module XKM 3000 L Med with a
XKM RS232 10 Med module to set up a serial interface.
