Possible cause and solution
The cup-rim sensor is not inserted or is incorrectly
inserted.
If the main dispenser is moving upward and the cup-
rim sensor is bumped, e.g., with a cup, the cup-rim
sensor loses its reference position.
 Confirm the message with OK.
 Reinstall the cup-rim sensor.
Cup-rim detection remains inactive and the main
dispenser stays in the top position until the coffee
machine is next switched on. Cup-rim detection is
reinitialized during the next switch-on operation.
The milk valve is faulty.
 Remove and clean the milk valve (see "Cleaning
and care – Removing and cleaning the milk valve").
