Software protection
Depending on the type of machine, it will have a number of software protections. The software monitors all
of the machine's inputs and outputs during the whole process. The software intervenes when a situation
occurs that shouldn't. This intervention usually results in the machine being switched off and an error
message displaying on the LCD. For possible solutions to this error message, see the below list of errors.

ERROR LIST
Error 1 Brewer is not running:
D The brewer motor starts after a drink is selected that uses FreshBrew coffee. If the microswitch does not
switch although the motor should be running, 'Error 1' displays on the LCD.
Error 2 Boiler temperature has been exceeded:
D If the temperature sensor (NTC) displays a value that is out of range (0 Ohm or infinite), the machine will
switch off and 'Error 2' will display on the LCD.
Error 3 Magnetic valve is open without selection:
D Pressing the start button switches on the solenoid valve. A timer is activated if the valve switches on
without pressing the start button. If the magnetic valve switches on again within the set time without
pressing the start button, there is either a leak in the water system or the water is boiling. The machine
switches off and 'Error 3' displays on the LCD.
Error 4 Calibration is taking too long:
D The time that the machine is on is recorded during calibration. If this time is too long, the machine
switches off and 'Error 4' displays on the LCD.
Error 5 Water selector in wrong position:
D The selector returns to the start position during start up and after each dosing. If the selector cannot find
its position during this routine, it switches off and 'Error 5' displays on the LCD.
Error 6 Magnetic valve is open too long:
D If the float tank takes too long to fill, whatever the reason, the machine will switch off and 'Error 6' will
display on the LCD.
Error 7 Wrong chip card:
D In a number of cases, a chip card can be inserted in a chip card reader in the keyboard. Data on the chip
can be downloaded or uploaded. If the software on this chip card does match the software on the
machine, Error 7 will display on the LCD.
Error 8 Communication error between both circuit boards:
D Communication takes place when the machine is starting up and when it is used. Communication takes
place through a flat cable between the keyboard and the control board. If communication fails, Error 8 will
display on the LCD.
