1.5 Safety features
•
F1 Drip tray full (option): the control panel is deactivated when the drip tray is full. Power to
the dosing valves (fig. 1-2) is also cut off.
•
F2 Heating: the control panel is deactivated when the hot water reservoir drops below the
minimum temperature.
•
F3 Filling: the control panel is deactivated when the hot water reservoir drops below the
minimum level. If the minimum level has not been reached for approximately 3 minutes, the
inlet valve switches off and the F3 Filling in the display is replaced by E3.
•
The heating element is fitted with a boiling-dry protection feature that can be reset externally.
1.6 Water reservoir level monitoring
•
Minimum water reservoir level. The heating element switches off when the minimum electrode
does not detect water. If the minimum electrode has not been reached after approximately 3
minutes the inlet valve deactivates and the message F3 Filling changes to E3.
•
Maximum water reservoir level. If the minimum electrode does not detect water, the inlet
slowly opens until the maximum level is reached again.
1.7 Temperature adjustment
The heating element only switches on when the water temperature is under the set value and when
the electrode 'sees' water. The temperature in the water reservoir is controlled by means of an NTC
precision feeler mounted on the exterior wall of the reservoir.
1.8 Coin mechanism (optional)
The machine contains a connection cable (flat cable) for an electronic coin mechanism. The coin
mechanism is powered from the control panel.
