A beverage preparation machine , such as a machine having a water source and a beverage preparation unit and an outlet for delivering a beverage to a beverage dispensing area , comprising a user-interface that has: - a generally peripheral illuminatable arrangement formed of illuminatable parts and extending around an inner portion ; and - a control arrangement for activating and deactivating an illumination of the illuminatable parts, such as a programmable control arrangement , for instance a control arrangement comprising a printed circuit board PCB and a controller e.g. a controller connected to the PCB by connectors , optionally the control arrangement controlling other functions of such machine such as an IT module, a pump, a thermal conditioner and/or a motorization of a preparation unit , the user-interface being optionally on a top part or front part or side part of such machine , wherein the illuminatable parts (11A-11F, 11A'-11H', 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) of the general peripheral illuminatable arrangement are in a side-by-side linear arrangement around the inner portion , such as a curved and/or angled linear arrangement, optionally the illuminatable parts of the general peripheral illuminatable arrangement being: - in a side-by-side single linear arrangement (11A-11F, 11A'-11H', 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) or in two or three or four generally parallel or concentric side-by-side linear arrangements; and/or - in a side-by-side linear arrangement (11A-11F, 11A'-11H', 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) in which two neighbouring illuminatable parts are immediately adjacent to each other (11A-11F, 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) or spaced apart (11A'-11H') by a spacer such as a part of a housing , characterized in that the control arrangement has at least one configuration, such as a programmed configuration, for successively activating consecutive parts (11A-11F, 11A'-11H', 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) in said side-by-side linear arrangement in a turning sequence about the inner portion with one or more repetitions of the turning sequence upon completion thereof to indicate to a user an execution of a beverage preparation procedure by centrifugation. - a generally peripheral illuminatable arrangement formed of illuminatable parts and extending around an inner portion ; and - a control arrangement for activating and deactivating an illumination of the illuminatable parts, such as a programmable control arrangement , for instance a control arrangement comprising a printed circuit board PCB and a controller e.g. a controller connected to the PCB by connectors , optionally the control arrangement controlling other functions of such machine such as an IT module, a pump, a thermal conditioner and/or a motorization of a preparation unit , - in a side-by-side single linear arrangement (11A-11F, 11A'-11H', 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) or in two or three or four generally parallel or concentric side-by-side linear arrangements; and/or - in a side-by-side linear arrangement (11A-11F, 11A'-11H', 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) in which two neighbouring illuminatable parts are immediately adjacent to each other (11A-11F, 21A-21G, 31A-31F, 41A-41B, 51A-51H, 51X) or spaced apart (11A'-11H') by a spacer such as a part of a housing , <EOS>
