Descaling
Regular descaling will prolong the life of your appliance and
will guarantee optimal brewing results for a long time.
• Follow the steps in the section headed “Preparing the
appliance for use” see DFU (Direction for Use manual)
• Instead of only water use a mix of water and Lemon sour.
• For the best result leave the mix of water and Lemon sour
for about 30 minutes in the appliance, before you start with
flushing the appliance.
• To get the best results repeat above-mentioned step once or
twice.
• When finished, flush the appliance twice by repeating the
above-mentioned steps only use water instead.
Volume adjustment
The new PCB circuit board makes it possible to adjust the
volume output by means of pushing the one-cup and two-cup
user controls.
How to adjust the volume output:
1. Be sure the boiler is fi lled properly, other wise perform fi ll
procedure see DFU for instructions.
2. Switch appliance on and wait until the unit is ready to
brew.
3. Be sure a
pod holder
is placed, but
without
a Coffee
POD. (Only adjusting with
plain
water)
4. Place a cup on the drip tray cover and push the one-cup
button.
5. When the appliance has fi nished it is stabilized to perform
the volume adjustment.
6. Empty the cup and push again for one cup setting,
measure the volume output with a graduated beaker.
In the table you can fi nd the requirements for the
minimum / maximum volume output cc/mL values
depending from the country version:
One-cup setting, Including Pod holder,
water spec
.
(Without Coffee pod)
Min. water cc/mL
Max. water cc/mL

7. Unplug the appliance from the mains.
8. Press the 1- and 2 cup button simultaneously and plug the
mains on.
9. When above step succeeded the led will turn on
continuously.
10. Depending if the volume has to de- or increase you have
to push the 1- or 2 cup button.
Every time you push the 1- or 2 cup button the LED
will turn off for 0.5 second (feedback to user) and the
pump time will be shorten or lengthen for 0.5 seconds
depending which button was pushed.
Pushing 1 cup
button pump, time will be
shorten
with
0.5 sec is approximately − 3.5 cc/mL (less coffee)
Pushing 2 cup
button pump, time will be
lengthen
with
0.5 sec is approxi 3.5 cc/mL (more coffee)
When the volume has to increase with 10 cc for example,
push the
2 cup
button 3 times.
The new value will be stored when you switch the
appliance off by pushing the main switch. (LED will turn
off )
11. Turn appliance on again and brew one cup, measure the
volume. In case the volume is not within specifi cation
repeat steps 6 - 11.
12. End.
Automatic filling procedure:
The Senseo PCB contains a new automatic fi lling procedure
software.
This fi lling procedure functions as follows:
First 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 and the
consumer pushes the one or two cup button, the Senseo will
start automatically the pump to fi ll the boiler.
When the boiler is fi lled the pump stops pumping.
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.
The old way of fi lling the Boiler by pushing the 1 and 2
cup button at the same time is still possible with this new
software.
Restoring the Boiler_empty_flag 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
Automatic fi lling
procedure
.
To
SET
the
Boiler_empty_fl ag
can be done by:
Keep the 1-cup button pressed while plugging in the power
cord of the appliance
.
To check if the
Boiler_empty_fl ag
is really set, you should
reconnect the power cord a second time to the net (do not
push any buttons).
The LED should blink very fast for 0.5 seconds at the
moment the power cord was connected to the net.
