from the connection PCB.

- Reassemble follow above steps backwards.

Remove the “lid closed” detection micro switch.

Disassemble brewing head.

- Unlock the snap lock which is holding the micro switch
assembly. (see picture for detail)

- Gently pull out the switch assembly.

- Reassemble follow above steps backwards.

To reach the components like pump, PCB, steam heater
placed on the base.

- First remove back cover, brew chamber, 3-way valve, steam
pump and boiler.

- Remove the 4 Torx T15 screws (two at the base and two at
the housing part.

- Bend the 2 click snap locks with a screwdriver (see base),
the housing can now be removed.

- To remove the rest of the housing unlock the 4 snap locks at
the base and gently pull of the front cover.

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 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. Select the Coffee function
normal volume

4. Be sure a pod holder is placed, but without a Coffee
POD. (Only adjusting with plain water)

5. Place a cup on the drip tray cover and push the one-cup
button.

6. When the appliance has fi nished it is stabilized to perform
the volume adjustment.

7. 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:

and select

One-cup setting, normal volume,

Including Pod holder, water spec. (Without Coffee pod)

Min. water cc/mL Max. water cc/mL

France version 104 120

General version 125 141

8. Unplug the appliance from the mains.

9. Press the one and two cup button simultaneously and
plug the mains on.

10. When above steps succeeded the main on/off switch- ,
one cup- and two cup button led will be on.

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 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 only be stored when you switch the
appliance off by pushing the main switch.
(LED will turn off)

12. Turn appliance on again and brew one cup, measure the
volume. In case the volume is not within specifi cation
repeat steps 7 – 11.

13. End.

Service test routines.

Sensors and buttons check mode.

The Senseo is equipped with a lot of sensor and push buttons.
To be able to check the function of those components a

special service routine has been applied.

1. Unplug the appliance from the mains.

2. Press the on/off- and two cup button simultaneously
and plug the mains on.

3. When above steps succeeded the main on/off switch- ,
one cup- and two cup button led will be on.

In below table you can fi nd which sensors or buttons
correspondent with the indication of the user panel.

For example push the one cup button and the light will be
on.

Automatic fi lling procedure:

The Senseo PCB contains an 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, one- and two cup led will light continuously.
This is only the case when the Senseo has not fi nished the

fi lling procedure completely! (First use)
This can be checked by reconnect the power cord a second

time to the net and check if the main switch LED will blink
very rapidly for approximately 1 second.

When the consumer pushes the one or two-cup button, the
Senseo will start automatically the pump to fi ll the boiler and
after that the Steam heater will also be fi lled.

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.

Restoring the Boiler_empty_fl 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_
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.

The main switch LED will blink very rapidly for
approximately 1 second.

To check if the Boiler_empty_fl ag is really set, you should
reconnect the power cord a second time to the net and
check if the main switch LED will blink very rapidly for
approximately 1 second.
