The machine is doing what it was set to do, not wearing out: a rinse that runs through the spouts at switch-on and switch-off, a descale or filter reminder counting the water that has passed through, an energy-save mode that darkens the screen after a quiet spell, or a demo mode left on from the showroom that lights the keys and pours nothing.
