When the machine is in standard operating mode, hold down the power button for five seconds; this will make the power light flash as well as the 95 light (94 light flashes on 2018 or newer models). From programming mode you can adjust multiple functions on the machine.
Tapping the hot water button in programming mode will bring the machine up one degree Celsius until it comes back down. The “95” preset is closer to 94 degrees Celsius. So illuminating the “100” light will set the brew boiler at 95 degrees Celsius, 105 at 96 degrees, etc.
To leave programming mode, tap the power button one more time and it will stop flashing and return to normal operation.
