Caution, the hinge spring on the back side of the appliance may
come out when the brewhead lid cover is being removed.
When reinstalling it, mind your ngers as this is a strong spring.
To remove the boiler (24):
Caution the boiler may still be hot!
To remove the back cover (31):
Place the appliance facing its backside. Using a small
screwdriver remove screw cover (28) and unscrew both
screws A. You can now remove the back cover from the
appliance, please be aware that the Water level sensor (32)
is still attached to the back cover.
To remove the brewhead lid cover:
Place a screwdriver on the positions (see picture) and
work your way to the bottm. Please be aware that due
to the construction of the brewhead, the space inside is
limited. There is a chance Hose (a) will come off the pillar
when opening the brewhead (22).
• Remove the back cover.
• Disconnect the Hose (a) to the brewhead.
• Unhook the 3-way valve (27) from its seat on the
bottom of the brewhead.
• Unhook the boiler from the snap hook on the bottom of
the brewhead.
• Disconnect the following leads:
- (x) Boiler +
- (y) Boiler –
- (w) Earth
• Remove Hose (b) from the bottom side of the boiler.
The boiler will not drain as long as the 3-way valve is still
connected to the top. You can now safely remove the
boiler from the appliance.
Note:
Please note, after replacing the boiler the appliance has to be
restored to factory default. The lling procedure (cold ush),
known from the predecessor Senseo’s is no longer available
after the ush before 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 ush procedure, causing the
thermal fuses in the heating element to fail. After a boiler
replacement or drained system, carry out the “Boiler reset”
procedure! Then the initial 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
6times 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
This type of descaler descales the appliance without
damaging it. For the correct amount, see the instructions
in the packaging of the descaler.
We advise you to use the special SENSEO® Descaler
(HD7011 or HD7012). 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).
