The machine says "ready to brew", I put the K-cup in the funnel, press the flashing button, display says it's brewing but nothing happens. This happens one out of every eight or nine brews. I turn machine off and wait five minutes then try again. Sometimes nothing happens again; sometimes it brews, but puts out more water than needed, but not two full servings. What's your take?
