摘要

A machine (1) for preparing a liquid food or beverage comprising: at least one outermost machine face selected from a front face (12), a top face and a lateral face (7); a means for emitting light (22) having at least one state of light emission and a state of light non emission and further having an illuminatable outer face (81, 101', 121) on said at least one outermost machine face (12), the illuminatable outer face (81, 101', 121) being arranged to be illuminated when in said state of light emission; and a control unit (20) connected to the light means. The control unit is arranged to detect at least one condition of such machine, in particular a condition involving a non immediate readiness of such machine to prepare a liquid food or beverage, and communicate said condition to a user via said illuminatable outer face (81, 101', 121) by changing the state of the light means (22). This illuminatable outer face (81, 101', 121) extends in at least one direction across a substantial part of the outermost machine face (12). Moreover, the illuminatable outer face (81, 101', 121) is arranged to be substantially entirely illuminated when in this state of light emission.
