Possible cause and solution
Fault 518–521
No flow was detected when dispensing from an external
container.
Exercise caution when handling process chemicals.
For all process chemicals, the 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 openings of the suction lances and
remove any deposits.
Check the hose connections on the suction lances, the
machine, and any dispenser modules.
Remove any kinks from the dispensing hoses and
check the hoses for leaks. Position the dispensing
hoses so that they cannot kink.
Vent the dispensing systems.
If you identify any leaks in the dispensing hoses or
defects on the suction lances, contact Miele Service.

Fault 555
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 wash items or injector nozzles.
When installing angled injector nozzles and sorting wash
items, ensure that the wash water outlets point towards
the centre of the wash cabinet.
Restart the machine. Excess water is pumped out
automatically.
Fault 559
There is a problem with the process documentation
interface. The machine has detected a module for an
Ethernet interface, but only a serial interface is activated in
the controls (RS232).
Deactivate the RS232 interface:
Open the menu for configuring the interface
Additional
settings
/
Interface
and then select
Ethernet
.
Wait approx. 90 seconds. The Ethernet module XKM
3000 L Med needs this time for initialization. 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.
