Abstract: A drinks preparation machine for preparing brewed drinks from a portion package with an extraction material includes a water tank, a pump, a water heater and a brewing chamber for receiving the portion package. The pump delivers water from the water tank into the brewing chamber via the water heater. A temperature sensor measures a temperature along the fluid path including an initial temperature at the location of the temperature sensor at least in one operating condition after a switching-on procedure or waking-up procedure and before a possible heating-up procedure of the water heater, and, after the water heater has reached an operating temperature, to carry out a rinsing procedure of the brewing chamber with water from the water heater, when and only when the measured initial temperature corresponds to a certain condition, and only subsequently to effect an introduction of the portion package into the brewing chamber.
