Cause and remedy
No flow was detected when dispensing from an external
container.
Take care when using 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 apertures of the siphons and remove
any deposits.
Check the hose connections on the siphons, the
washer-disinfector and any dispensing 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 siphons, contact the Miele Customer
Service Department.
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.
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.
