Notas:
1- To remove the water tank (an LED - red - indicates when empty) simply pull on the slot which delimits the left of the device.
2- There is a power switch behind (bottom right) near the connection of the power cable. It is useless after the first use, the switch. The device will automatically economy and then alone stop (then remains only a red LED lit).
3- A signal - red - indicates on légouttoir it is full.
4- I do not think the quality of coffee is quite proportional to the pressure. 15 bar pressure seems a good compromise (noise-vibration-strength / quality).
5- The packing of coffee you put into the filter holder is important. More tamp your coffee with doser supplied and your coffee will be.
