DISASSEMBLY- AND RE-ASSEMBLY ADVISE
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
locks at the base and gently pull of the front cover.
- To reassemble follow above steps backwards.
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

REPAIR INSTRUCTION
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 filled properly, other wise perform fill
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 finished 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 find 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
France version 104 120
General (Europe) version 125 141
Spain version 55 71
Brazil version 65 81
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 approximately + 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 specification
repeat steps 6 - 11.
12. End.
Automatic filling procedure:
The Senseo PCB contains a automatic filling procedure
software routine.
This fill routine is only meant for back-up.
Normally the consumer has to follow the guidelines stated in
the DFU.
The filling procedure functions as follows:
The consumer has to fill 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 finished the filling procedure
completely! (First use)
When the consumer pushes the one or two-cup button, the
Senseo will start automatically the pump to fill the boiler.
When the boiler is filled the pump stops pumping.
(Pump time approximately 22 seconds)
When the filling procedure has been successful the software
will clear a Boiler_empty_flag in the Eeprom.
By means of this Boiler_empty_flag the system knows the
boiler is filled or not!
When the Senseo is switched off or disconnected from the
mains, the value of the Boiler_empty_flag is stored in the
Eeprom chip.

REPAIR INSTRUCTION
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_
flag again to production default.
Bringing the Senseo back into production status, has the
benefit the flush routine will be activated automatically
when installed by the consumer, see topic Automatic filling
procedure.
To SET the Boiler_empty_flag 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_flag 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.
