A coffee machine is provided with a housing frame (10), with at least one extraction device (20) for production of the coffee, an electronic control unit (40) and a hot water or steam supply (50). The extraction device (20), the control unit (40) and the hot water or steam supply (50) are each assigned to a black box (62, 63, 64, 65) provided with at least one transponder or similar for recording certain data and/or registration of certain functional processes. The recorded data can be analysed, notably by a computer program. In this way the coffee machine can be optimally serviced and hence the lifetime of the individual functional units increased.
