Resposta para "Barista machine won't start"EASY FIX on newer models: If you have the ‘no power’ overheat problem on the later version of the Starbucks barista, mine has an extra sensor directly over the water inlet to the boiler that looks like the others (brown plastic with two spade connectors). Unplug machine. Between the two metal spades is a brown plastic ‘button’ / tab poking up that can be pushed down firmly with a ‘click’ to reset the overheat trip. Your machine should now work. Next you need to descale it!
