When the switch is pulled upwards no cold water is mixed with hot water from the steam
boiler. In this position near-boiling water with some steam may leave the spout.
The steam boiler will re-fill automatically, also activating the pump. A flow restrictor with
an opening of 0.6 mm diameter regulates the inflow such that the heating element can
warm the incoming water as efficiently as possible.
However, the boiler will not fill when a shot is pulled as not to disturb the process of
espresso extraction by a fluctuating water pressure.
Steam
The left valve is the steam valve (see figure 1, item 12). Turning the steam valve knob
(figure 1, item 11) counter-clockwise will open the valve. Before steaming milk it is
necessary to open the valve for a short while to purge the water from the steam wand.
This water is condensed steam from the last use and new condensation from steam
coming in contact with the cold tubing, valve and wand. Position the tip of the steam
wand over the drip tray when purging the condensation.
Warning!
The steam valve is a spring loaded valve with the spring actually keeping the valve
closed. Use no force to close the steam valve since this will wear down the rubber and
silicone parts within the valve. Fasten just until no more steam is leaving the tip, at that
point the valve is closed. Total travel of the knob from close to fully open is about ¼
turn.
Set boiler temperatures
The factory settings of the coffee boiler temperature and steam boiler temperature are
93 and 135 degrees Centigrade (°C) respectively. The 135 °C is approximately
equivalent to 2.4 Bar steam pressure.
Coffee boiler
The display of the PID-regulator of the coffee boiler is located on the front panel of the
machine in between the on/off switch and the model tag (see figure 5).

Procedure to change the coffee boiler temperature
