“Empty drip tray” - message
Function:
The residual water level is monitored using a capacitive
sensor. The sensor is located approximately halfway up the
upper edge of the drip tray. To ensure the best possible
use of the drip tray capacity, the sensor is located near to
a dam. Therefore, the drip tray fi lls up to the upper edge
of the dam and over fl ows inside, triggering the sensor and
thus the “Empty drip tray” message.

“Water low” message (water reserve)
Function:
The water level is monitored by a capacitative sensor, located one
third of the way up the water tank wall.
If the electronics assembly detects, by means of the sensor,
that the amount of water in the tank has dropped below the
above mentioned level, a water reserve remains available for the
dispensing process underway (this will cover 200 turbine pulses).
The product dispensing process will then come to an end.
If a dispensing cycle ends after the sensor has been triggered (in
the reserve) then the display “Water low” continues to be displayed
during the following dispensing cycle.
