(if detected during dispensing: a cup cycle is ended, a pot cycle is interrupted)
This is not applicable if a fixed water connection is installed. (the sensor is not connected)
If the water tank is empty or the water supply is interrupted (in case of a fixed water connection)
and the boiler is not filled, the heating element will be switched off to prevent overheating and
the dosing is disabled to prevent bad dosing.
Off Water is present inside the water tank / correct water supply to the boiler.
Blinking The LED starts to blink when the boiler is not filled within 25 seconds (or 120
seconds after the machine has been switched on) while the inlet valve is open. In case a
fixed water connection is present it indicates that the water supply is interrupted or shut off.
More than 500 ml/16.9 fl oz water has been supplied in the stand-by mode.

IR transmitter/receiver in the dosing coil assembly. If no concentrate is detected the IR beam
is not interrupted and the LED will light on. Coffee dosing is stopped 50 dosing pulses after
the empty detection signal. (to dose the remaining 5 ml. in the tube)
Hot water remains to be delivered thereafter from the coffee outlet.
