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.

REPAIR INSTRUCTION

HD7825/60

Note:

Please note after replacing the boiler the appliance has to be
restored to factory default. The fi lling procedure (cold fl ush),
known from the predecessor Senseo’s is no longer available
after the fl ush before fi rst 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 fl ush procedure, causing the thermal

fuses in the heating element to fail.

After a boiler replacement or drained system, carry

!

out the “Restore boiler_empty_fl ag to factory default”
procedure! Then the initial fl ush 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descaling mixture is no longer active.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 fi lled properly, otherwise perform
fi ll procedure see DFU for instructions.
