Keurig K-Mini powers on but doesn't brew (brew mode won't activate)

Got a brand new Keurig K-Mini as a gift. After filling the reservoir with water and pressing the power button (which lights up) and after lifting and lowering the handle to activate brew mode, the brew indicator light doesn't flash and nothing happens when I press the big K button. What happened? What should I do?
