Before you start dismantling!
For your safety be sure the plug is disconnected
from the mains!
The product is designed for easy access to the internal
components.
Make sure that all accessories like tank, podholder, drip tray,
spout and collector have been removed.
To remove the back cover, follow below steps:
- Remove the two Torx screws (T15) A(see exploded view).
- Remove the valve outlet.
- Start at the upper side of the back cover, using a flat head
screwdriver to unhook the top of the back cover and gently
pull the back cover from the appliance so that a little chink
between back cover and brew chamber becomes visible.
- Again use the screwdriver to unhook the two “snap locks” at
each side of the back cover, and gently move the screwdriver
in the direction of the opposite side of the appliance, in
such a way that the lips of the snap locks are bent outwards
and unhook.
- If all snap locks are unhooked, it is possible to remove the
back cover. Gently pull the back cover upwards to release
the bottom part of the back cover from the housing.
Please note that the back cover is still connected to the
pump.
- For reassembly follow these steps backwards.
To remove the brew chamber lid cover, follow
below steps:
- Place a large screwdriver on the
positions (see picture 1) and
lift the cover over the snap
locks on both positions, use
appropriate force.
- The cover lid can now be lifted
up, but stays attached to the
brew head by the push rod, to
remove the complete cover
including lever and push rod
squeeze both legs of the push
rod strongly together
(see picture 2), so that the two
pins will unhook 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.
- To reassemble, follow steps backwards, without using a
screwdriver.

DISASSEMBLY- AND RE-ASSEMBLY ADVISE

HD7828/10 / HD7828/11
Note:
Please note after replacing the boiler the appliance has to be
restored to factory default. The filling procedure (cold flush),
known from the predecessor Senseo’s is no longer available
after the flush before first use has been executed. When the
“restore to factory default” procedure is not carried out, a new
and empty boiler can be switched on, without having the
protection of the initial flush procedure, causing the thermal
fuses in the heating element to fail.
After a boiler replacement or drained system, carry
out the “Restore boiler_empty_flag to factory default”
procedure! Then the initial flush procedure can be
carried out.
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. Make sure the boiler is filled properly, otherwise perform
fill procedure see DFU for instructions.
2. Switch appliance on and wait until the unit is ready to
brew.
3. Make 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
Small cup (60ml) 61 81
Normal cup (125 ml) 123 143
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.

REPAIR INSTRUCTION
Filling procedure:
Please note, the software of the Senseo Viva Café has changed,
compared to predecessor Senseo’s! The filling procedure
known from predecessor Senseo’s is no longer available.
The command originally used to initiate the filling procedure
(cold flush: pushing both the 1-cup and 2-cup buttons
simultaneously) will now start the decalcification process.
To perform a cold flush of the appliance, it has to be reset to
factory default. See topic “Restoring the Boiler_empty_flag
to factory default” below.
As a back-up, when the appliance is in factory default setting,
the cold flush will also be initiated when the user presses
either the 1-cup or the 2-cup button. This functionality is
only available after restoring the Boiler_empty_flag to factory
default.
Restoring the Boiler_empty_flag to factory
default
Under some circumstances it might be necessary that the
boiler of the Senseo is emptied.
This, for instance, during wintertime were the possibility
exists that the boiler becomes frozen during transport.
For those occasions it is useful to restore the Boiler_empty_
flag to production default.
Bringing the Senseo back into production status, has the
benefit that the flush routine will be activated automatically
when installed by the consumer, see topic Automatic filling
procedure.
To SET the Boiler_empty_flag:
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.
