IV. PROGRAMMING AND USE
Three buttons are integrated into this control board and each serves a particular
purpose. The 1 Shot and 2 Shot espresso buttons allow for automatic coffee delivery,
while the Stop button is for continuous coffee brewing.
1. Programming standard dose
Please follow the instructions below for programming coffee dosage for drink
buttons.
Step 1: Press and hold the 1 Shot espresso button or 2 Shot espresso
buttons for 3 seconds to start to program on that one. Siren sounds
and the selected button begin flashing.
Step 2: Press the Stop button to dispense coffee and press it again when
reaching the desired coffee dose. The Stop button light is on while dispensing.
Step 3: Press and hold the programmed button for 3 seconds to save its new dose
and finish the setting process.

6
S21-037
Repeat the procedure above for programming on the remaining button.
2. Coffee dispensing
Press the Stop button once to start the coffee brewing process, then
press it again to stop
Press the 1 shot espresso button or 2 shot espresso button
to dispense a preset coffee dose that is previously programmed.
3. Automatic group cleaning
It’s feasible to automate the group cleaning procedure by step below:
Press and hold the 2 shot espresso button for at least 5 seconds until the
siren stops sounding and the machine starts to discharge water.
The cleaning time and period can be modified by the user (page 9).
4. Pre-infusion
To enable the pre-infusion mode, press and hold the button for 3
seconds until the siren sounds.
Do similarly the step above to disable it
Note: The coffee dose on buttons needs to be reprogrammed for it to work
correctly.
5. Filling
When the boiler is in an out-of-water state for more than 2.7 seconds, the pump
and filling valve will automatically open to fill up the boiler. The siren sounds
continuous until the boiler’s water level is enough.
After being full of water for 2.7 seconds, the filling process will automatically
stop.

S21-037
Note: The water source should always be available for filling operation.
6. Setting of operational parameters
In addition to the core functions, a machine’s operational parameters can be changed
to improve the user experience.
