  Kimberly MarksSep 12, 2025
  If your Siemens Coffee Maker displays “Milk container connected?” despite a connected milk container, it could be because the container is outside the range of the sensor, or the material (e.g., milk carton) is not recognized. To resolve this, position the container at the right edge, confirm the display request with “Yes,” or use the enclosed milk container.

  If the coffee from your Siemens Coffee Maker has no “crema”, it could be due to an unsuitable type of coffee, the beans are no longer fresh, or the grinding level is not suitable for the beans. To resolve this, use a type of coffee with a higher proportion of robusta beans, use fresh beans, or adjust the grinding unit to a finer setting.
