How do I activate Test Mode on the Magnifica Evo?

To activate Test Mode, the appliance must be plugged in and in stand-by mode. Remove the drip tray so the Grounds Container icon flashes, then hold the required combination of three buttons (depending on your model) until the Grounds Container icon turns off and certain button LEDs begin flashing. You must access the desired test function within 10 seconds, otherwise the machine will automatically return to stand-by mode. (Page 10-11)
