Disassembly information
To remove the brew chamber lid cover handle as follows:
•Place the screwdriver on the
positions (see picture 1) and
lift the cover over the snap
locks on both positions.
•The cover lid can now be
lifted up a little and to
remove the complete cover
including lever and push rod
squeeze strongly with two
fingers both legs of the push
rod (see picture 2) to each
other, so that the two pins will
get out of the hinge position
on the brew chamber.
•To remove lever from lid cover, take a screwdriver and
bend carefully the two lips/ribs in the lid cover outwards
and push the lever with force out of the hinge.
•Reassemble follow steps backwards, without using a
screwdriver.
To remove the back cover handle as follows:
•Remove valve outlet.
•Start at the upper side of the back cover and stick a
screwdriver into the 2 snap locks positions and gently
pull the back cover from the appliance so that a little
chink between back cover and brew chamber becomes
visible.
•Put the screwdriver in to the 4 rectangular holes (snap
locks) at the back and gently pull the screwdriver such
away that the lips of the snap locks are bent outwards.
•If all clicks positions are loose, it is possible to remove the
back cover.
•Reassemble follow steps backwards.

Removing Brew chamber head handle as follows:
•Disassemble back cover!
•Place the appliance such a way that you are looking at
the boiler.
•First remove the boiler from the snap lock position of the
brew chamber.
•To remove the brew chamber,
use your both thumbs (see
picture 3) and push strongly
with a little distortion
(rotation) until the brew
chamber comes loose.
•Reassemble follow above steps backwards.
To reach the components placed on the base handle as
follows:
•First remove back cover, brew chamber and 3-way valve.
•Remove both Torx T15 screws see exploded view in the
near of position A.
•Bend the 2 click snap locks with a screwdriver (see base),
and the housing can now be removed.
•To remove the rest of the housing unlock the last 4 snap

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® coee 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 lled properly, other wise perform
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 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 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 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 Coee pod)
Min. water
cc/mL
Max. water
cc/mL
France version 104 120
General (Europe) version 125 141
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 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 main switch.
(LED will turn o)
11. Turn appliance on again and brew one cup, measure
the volume. In case the volume is not within
specication repeat steps 6 - 11.
12. End.
Automatic lling procedure:
The Senseo PCB contains a automatic lling procedure
software routine.
This ll routine is only meant for back-up.
Normally the consumer has to follow the guidelines stated
in the DFU.
The lling procedure functions as follows:
The consumer has to 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 nished the lling procedure
completely! (First use)
When the consumer pushes the one or two-cup button, the
Senseo will start automatically the pump to ll the boiler.
When the boiler is lled the pump stops pumping.
(Pump time approximately 22 seconds)
When the lling procedure has been successful the
software will clear a Boiler_empty_ag in the Eeprom.
By means of this Boiler_empty_ag the system knows the
boiler is lled or not!
When the Senseo is switched o or disconnected from the
mains, the value of the Boiler_empty_ag is stored in the
Eeprom chip.

Restoring the Boiler_empty_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_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.
To SET the Boiler_empty_ag can be done by:
Keep the 1-cup button pressed while plugging in the
power cord of the appliance.
The main switch LED will blink very rapidly for
approximately 1 second.
To check if the Boiler_empty_ag is really set, you should
reconnect the power cord a second time to the net and
push the main switch.
The main switch LED should light continuously.
