Descaling
Descaling is an important element in Senseo maintenance.
It should be done at least once every 3 months, up to 6 times
a Year!
This will prolong the life of your appliance and will guarantee
optimal brewing results for a long time.
Use the correct descaling agent.
Only citric acid-based descalers are suitable for descaling
the SENSEO
®
machine. This type of descaler descales the
appliance without damaging it. For the correct amount, see
under ‘Descaling procedure’ below. Each descaling mixture
can be used only once. After use, the descaling mixture is no
longer active.
We advise you to use the special SENSEO
®
Descaler
(HD7006). Read the instructions on the package of the
descaling agent.
Never use a descaling agent based on mineral acids such as
sulphuric acid, hydrochloric acid, sulphamic acid and acetic
acid (e.g. vinegar). These descaling agents may damage your
SENSEO
®
coffee machine.
• Follow the steps in the section headed “Descale the
appliance” see DFU (Direction for Use manual)
Volume adjustment
The 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, podholder 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:

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 one- or two 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 shortened or lengthened 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 fi lling procedure:
The Senseo PCB contains a 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 will light continuously. This is only the case
when the Senseo has not fi nished the fi lling procedure
completely! (
First use
)
When 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.
(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.
