Rinse

Handling of the Postpone Rinse Command

The “PostponeRinse” command postpones a requested rinse from the coffee machine. For example, if a customer is placing an order at an external interface, the coffee machine should not rinse, otherwise the rinse will end up in the customer’s cup. To avoid this, the rinse can be postponed with the “PostponeRinse” command. The rinse can be triggered again with the “ForceRinse” command after the user interaction is completed, so that the machine is ready to take the next order.
