Heat up
1. Switch all three heat switches ON (lever up).
This allows power to be fed onto the SSR’s in the
machine.
2. Check if all the green indicator lights underneath the electrics box are lighting up (see Figure 11).
a. If a single indicator light does not light up, it is possible that the corresponding overheat
safety switch has cut-out during transport:
Turn the machine OFF (MAIN switch and all 3 HEAT switches), remove the appropriate
body panel and press the central button of the overheat safety switch inward to re-set (see
Technical manual).
b. If corresponding indicator lights of a heat circuit (e.g. both most left lights of each set) do
not light up it is possible that the corresponding auto-fuse has cut power to that circuit.
Open the electrics-box (see Technical manual) to check the circuit breakers.
Figure 11. Indicator lights (and external sensor jack) underneath the electrics box. In a Duette the
most right indicator (3) is not present. The above situation (all indicators are lit) indicates that all
heating elements receive power.
3. Check heating up: When all indicator lights are lit (see Figure 11), the boilers will be heating up
(unless the heating element is not functioning) and the temperature readings on the displays will
increase. The steam boiler temperature will initially only rise very slowly as the sensor is located
above the water level.

4. Heating up from 20°C to operational temperature will take about 15 minutes, during this heat-up:
Check expansion pressure: Make sure that all groups are filled with water (activate all groups and
check if water flows from each group immediately). Mount a blind filter in the left group and
activate that group using the “continuous button”. Pressure will rise to pump pressure rather
quickly and then slowly rise to a maximum pressure: the expansion pressure. The cold water
heating up is expanding which leads to increasing pressure until the expansion valve starts to spill
drops of water into the drain. The expansion pressure should be in the range 11-13 bar (contrary
to other machines we made the expansion pressure cannot be adjusted on this machine).
5. This would be a good moment to set/adjust a few parameters
in the “technician level” of the
controller:
On the touchpad: touch
the “MENU” button, then the “SETTINGS” button, then the “TECHNIC
LEVEL
” button. In the next window construct the technician password using the arrows (the
number 66666)
, then touch “ENTER”. In the next windows a service telephone number can be
stored, the level-probe sensitivity can be adjusted (low-medium-high, depending on water
conditions), the choice made between filling possible during brew or not, and the flow-meter type
adjusted (after changing flow-meters).
