"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 flow 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.

Filter off:
If the function is turned off the electronics assembly
monitors the flow meter pulses, recording one pulse
each turn.
Filter on:
If the function is turned on the electronics assembly
monitors the flow meter pulses, recording one pulse
every two turns.
"Change water filter" message
The electronics assembly uses the flow meter
impulses to keep track of the amount of water which
has flowed through; after the specified amount (set
in accordance with the water hardness level), the
"Replace filter" message appears.
