Yes, you can adjust the water temperature of the coffee water only, and there are 2 options: Standard and High.
Changing to High temperature will adjust by only a maximum of 2° Celsius.
With the machine on and ready, make sure the mode selection dial is set to Espresso Press and hold the "x 2" and "My" coffee buttons simultaneously for at least 3 seconds to access the
water temperature setting.
The "water tank" and "tamp" light flash alternately and the "temperature" light remains on steady. This indicates you can choose the desired temperature setting.
Press the button that corresponds to your desired temperature and the machine is ready to use.
