Water, milk and coffee beans are available and gives an appropriate if needed
Report what the user needs to refill. If everything is available, the user chooses one
Coffee and the machine brews the selected drink. The machine then rinses
short and then turns off.

display. Please note that not all activities are listed above. Complete
Make this sense. Please note that you also have the communication between vending machine and
To model users, i. all displays of the machine and all inputs of the machine
User are listed

Use partitions / swimlanes to control the interaction between user and machine

Your flow is correct, you just need to introduce partitions to separate the user facing and machine internal tasks.
