Automatic fi lling procedure:
The Senseo PCB contains an automatic fi lling procedure
software routine.
This fi ll routine is only meant for
back-up .
Normally the consumer has to follow the guidelines stated in
the DFU.
The fi lling procedure functions as follows:
The consumer has to fi ll the water container and has to plug
the appliance on the mains.
When the Senseo main switch has been pushed the main
switch led, one- and two cup led will light continuously.
This is only the case when the Senseo has not fi nished the
fi lling procedure completely! (
First use )
This can be checked by reconnect the power cord a second
time to the net and check if the main switch LED will blink
very rapidly for approximately 1 second.
When the consumer pushes the one or two-cup button, the
Senseo will start automatically the pump to fi ll the boiler and
after that the Steam heater will also be fi lled.
When the boiler is fi lled the pump stops pumping. (Pump
time approximately 22 seconds)
When the fi lling procedure has been successful the software
will clear a
Boiler_empty_fl ag in the Eeprom.
By means of this Boiler_empty_fl ag the system knows the
boiler is fi lled or not!
When the Senseo is switched off or disconnected from the
mains, the value of the
Boiler_empty_fl ag is stored in the
Eeprom chip.
Restoring the Boiler_empty_fl ag to production default:
Some times it is needed that the boiler of the Senseo have to
be emptied.
This for instance in wintertime were the possibility exists that
the boiler becomes frozen during transport e.g.
For those occasions it is handy to restore the
Boiler_empty_
fl ag again to production default in the Eeprom.
Bringing the Senseo back into production status, has the
benefi t the fl ush routine will be activated automatically
when installed by the consumer, see topic

Boiler_empty_fl ag is really set, you should
reconnect the power cord a second time to the net and
check if the main switch LED will blink very rapidly for
approximately 1 second.
