“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 ow meter
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.
