During assembly
•Make sure that the wiring is properly dressed as
in the original situation. When replacing crimp
connections or tie wraps, perform a pull test.
Prevent entrapment of wiring between housing-
or internal parts.
•Make sure that all parts are re-assembled, and
that no parts are forgotten. E.g.: sleeves, internal
protection caps, screws.
•Make sure that the housing parts are properly
assembled. No gaps should be present, yet
make sure screws are not overturned.
After assembly:
•Check all relevant functions of the appliance.
•Check if the consumer complaint has been
resolved.
•Check for abnormalities. E.g.: leaking liquids,
smoke, smell, abnormal noise.
•Check the use safety functions. E.g.: lid-open
detection switch, motor disable switches.
•Check the electrical safety functions:
- leakage current
- high voltage (servicer to perform a test)
- earth continuity (servicer to perform a test)

SENSEO coee boost technology
Get the most out of your coee pad thanks to the
innovative SENSEO® Coee Boost technology that
delivers a fuller, richer avor through:
A new ner distribution of water via 45 aroma
nozzles ensuring the hot water is optimally spread
across the entire SENSEO® coee pad.
Therefore each grain of ground coee will release
all the aromas and avors, delivering a richer, fuller,
taste.
Crema improvement
With Crema plus you will brew, cup after cup,
SENSEO® coee with the nest and most velvety
crema layer.
Intensity select
The new PCBA has an extra feature onboard
“Intensity select”, which need to be enabled for
the following type numbers (HD6554, HD6555 &
HD6556).
Intensity select how does that work:
•Select the strong short coee
recipe by double tap on the
1-cups button for 1 cup of
strong short coee.
•Press the 1-cup button once
for one large mild cup of
coee.
•Select the strong short coee
recipe by double tap on the
2-cups button for a double
cup of strong short coee.
•Press the 2-cup button once
for two large mild cups of
coee.
Selecting the right PCBA modus
Enable/Disable the “Intensity select” feature.
The PCBA is standard delivered with the “Intensity
select” feature disabled, this for easy servicing the
existing SENSEO® Original HD78xx & HD6553
range with OPR Boiler installed.
The “Intensity select” function can be simple

1. Hold the 2-cups button while applying power
to the appliance.
2. Release the 2-cups button.
3. Press the 1-cups button to conrm the action
of changing the “Intensity select” functionality.
4. Release the 1-cup button.
Once changed, please check functionality by
making a coee and double press the 1-cup
coee button, the volume of the coee should be
±60 ml. (water 61 – 81 ml)
To change back the “Intensity select” function
again, simply repeat steps 1 to 4.

Volume adjustment procedure
If you have replaced the PCBA for whatever reason,
you always need to check/adjust the volume
setting from this new PCBA. The PCBA coming from
service has standard the WEU volume setting pre-
installed.
Specication table, water specication normal/
strong 1-cup SENSEO recipe:
In-cup volume
(ml) water
1-cup (ml)

Due to the “Intensity select” function, the volume
programing procedure has changed.
For proper coee volume adjustment, for both
volumes normal/smooth cup 122/100 ml and
short/strong cup 60 ml two parameters need to be
(re-)programmed.
1. Coee volume 122 ml (WEU) / 100 ml
(French/Spain) (Hall sensor should be
activated, make sure a lled water tank is
placed on the machine)
2. Scale factor (this scale factor, need adjustment
to ensure that for both version 122/100 ml the
small cup volume remains 60 ml.) (Hall sensor
should be de-activated, make sure water tank
is removed from the machine)
First setup, check current water specication:
1. Make sure boiler, is lled with water.
2. Switch appliance on and wait until the unit is
ready to brew.
3. Place a 1-cup pod holder without a Coee
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 nished, you are able
to perform the volume adjustment.
Adjusting the normal 1-cup volume
(WEU or French/Spain)
6. Empty the cup, podholder and push again for
one cup setting, measure the volume output
with a graduated beaker.
In the table above you can nd the
requirements for the minimum / maximum
water volume output cc/ml values.
7. Unplug the appliance from the mains.
8. Make sure the water tank is lled and placed
on the machine.
(for adjusting the right parameter, the internal
SW will check if the water level sensor is
activated yes/no.)
9. Press the 1- and 2-cup button simultaneously
and plug the mains on.
10. When above step succeeded the led will turn
on continuously.
11. 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 o 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 coee)
Pushing 2-cup button pump, time will be
lengthen with 0.5 sec is approximately
+ 3.5 cc/mL (more coee)
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 o by pushing the on/o switch.
(LED will turn o)
12. Turn appliance on again and brew one cup,
measure the volume. In case the volume is not
within specication repeat steps 6 - 12.

(60 ml) cup volume.
13. Remove the water tank from the machine. (for
adjusting the right parameter, the internal SW
will check if the water level sensor is activated
yes/no)
14. Press the 1- and 2 cup button simultaneously
and plug the mains on.
15. Release the 1- and 2 cup button, if successful,
the on/o LED will switch on less bright/
intense as normal, indicating the scale factor
reprogramming has entered.
16. 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 o for 0.5 second (feedback
to user) and the scale factor will be shortened
or lengthened depending which button was
pushed.
Pushing 1-cup button, scale factor will be
shorten approximately - 1 cc/ml (less coee)
Pushing 2-cup button, scale factor will be
lengthen approximately + 1 cc/mL (more
coee)
The new value will be stored when you switch
the appliance o by pushing the main switch.
(LED will turn o)
17. Turn appliance on again and brew one strong
coee cup by pressing the 1-cup button twice,
measure the volume. In case the volume is not
within specication repeat steps 13 – 17.
18. End
Example table, switching from WEU to French/
Spain specication or vice versa, you need to
execute below:
Restoring the Boiler_empty ag to production
default:
Sometimes 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_ag again to production default.
Bringing the SENSEO back into production status,
has the benet the ush routine will be activated
automatically when installed by the consumer, see
topic Automatic lling procedure.
How to SET the Boiler_empty_ag:
Keep the 1-cup button pressed while plugging
in the power plug of the appliance in the mains
socket.
The main switch LED will blink very rapidly for
approximately 1 second.
To check if the Boiler_empty_ag is really set,
reconnect the power plug to the mains a second
time and push the main switch. The main switch
LED should light continuously.
