The cup rim sensor (rocker) on the central spout is not switched while coffee is being dispensed.
The coffee machine automatically interrupts the drink preparation process after the central spout has moved down completely and the cup rim sensor (rocker) has not been switched.
Make sure that the cup rim sensor (rocker) can move up to the cup rim freely.
If the container has a very wide opening that prevents the cup rim sensor from making contact with the edge of the container (e.g., in the case of a very large cup), the drink will be canceled. Use a different container or position the existing one so that the sensor can detect the rim.
