B9. Liquid waste tray level sensor
When the waste in the tray reaches the maximum level, this sensor detects it by the continuity of the two
electrodes in contact with the liquid.
The machine will show the
“
Liquid tray full
”
error on the display.
The waste must be removed from the machine before it can be used again.
When the machine features an external drain, the liquid level in the tray will not activate this sensor.
The surface of the contact terminals should be cleaned after each drainage operation to prevent dirt from
accumulating and interfering with the correct operation of the sensor.
B11. Cream adjustment control
This is a manually-operated knurled knob, located on the support arm of the dispenser tubes. It can be
used to adjust the micro-injected air used to froth the milk and make the cream. In the clockwise
direction, it closes the flow of air from the outside and in the counter-clockwise direction it opens it. The
knob features a safety locknut that must be released before performing any adjustment.
The machine is fine-tuned at the factory for the optimum cream setting. This setting can be changed,
according to the type of milk, increasing or decreasing the flow of air to prepare cream with the desired
density. This control does not need frequent adjustment. The user can check the results to establish the
time it needs to be adjusted, for example, signs of the need for new adjustment include a lower cream
quality or density, irregular flow, excessive bubbling, splashing, etc.
