2. If the recipe button keeps blinking slowly after the portafilter is moved to the right and the machine does not start grinding, it might mean that the portafilter was not inserted completely while moving it to the right. Give the portafilter handle a little push to connect it well into the machine. The machine will start to grind the beans. Always make sure you insert the portafilter into the machine fully, until you hear a click.
