Disassembly- and Reassembly advice
Make sure the appliances cordset is disconnected from the mains!
To open the appliance, remove all detachable parts: Water container, driptray and cover, pod holder and collector.
1. To reach the brew chamber.
1.1. Open the top cover.
To open the top cover the brew chamber needs to be unlocked. Start at the back side of the top cover, using a
plastic tool, and trace along the parting line of the top cover, undoing all the snaps. There are two small snaps on
the front lower side of the brew chamber, undo them with a small athead screwdriver (No. 0)
The top cover needs to be tilted forward to be removed. The at cable Wfrom the main PCBA to the UI PCBA is still
attached to the User Interface panel, and can easily be unplugged.
The brew chamber can now be removed by unscrewing the two screws (C, T15), and undoing the hose connection
(g) from the one way valve.
2. To reach internal components like Boiler or Pump.
2.1. Remove the screw (A, T15) from the bottom side of the appliance.
2.2. Remove the screw (B, T15) from the bottom side of the appliance to remove the back plate and undo the hose
connection (g) from the one way valve (if not done so already).
The socked tube (a) is still connected to the water container socket, and can easily be pulled o.

2.3. Remove the housing.
To remove the housing, start at the back side and undo the clicks (1) on either side of the back plate, next undo the
snaps on the front of the housing (2), undo them with a athead screwdriver. Make sure that none of the snaps snap
back.
Remove the housing upwards from the rest of the appliance, but mind at cable running through the guide on the
inside of the housing and the water level sensor still connected to the inside of the housing.
You can now access the Boiler and Pump, to remove them, undo the electrical connections and hoses, and reinstall in the
reverse order. Any Ty-wrap that has been removed needs to be replaced by a new one, and tightened with the specied
forces.
3. To replace the PCBA.
3.1. Unscrew the inner frame.
Unscrew the two screws (D, T15) holding the inner frame in place, take special care to note the proper wire routing,
and make sure reinstalling the PCBA will be done in an identical way.

Repair instruction
Descaling
Scale builds up inside the machine during use. It is essential to descale the SENSEO® coee machine when the CALC Light
goes on. If the descaling procedure is not performed correctly, scale residue remains behind in the machine. This causes
scale to build up more quickly and may cause permanent and irreparable damage to the machine.
Use the correct descaling agent (HD7011, HD7012 only). It has been developed to ensure better machine performance and
operation. Never use a descaling agent based on mineral acids such as Sulphuric acid, Acetic acid (vinegar) or Hydrochloric
acid. These descaling agents may damage your SENSEO® coee machine.
For detailed instructions please refer to the Directions For Use, chapter CALC.
Volume adjustment
Note: Volume adjustment may only be carried out in case the repair technician is sure there is no underlying cause (e.g. User
programmable volume, leakage, incorrect voltage setting, etc.) for the deviation in volume from the factory default.
Every time a PCBA is replaced for whatever reason the 1-cup & 2-cup setting both need to be separately
adjusted/calibrated!
There is no country selection option therefore adjust both 1-cup & 2-cup recipes within the right volumes
following the table page 2.
For the correct procedure on Volume measurement, please refer to the SENSEO® Repair process.
How to adjust the volume output:
1-cup
1. Make sure the boiler is lled properly, otherwise perform the Flush before rst use procedure, according to the
instructions in the DFU.
2. Make sure the top collector and 1-cup pod holder, without a coee pod is installed in the appliance.
Calibrate the scale you are going to use for the measurement, by placing the empty cup and switching it on.
3. Press the 1-cup coee button to start a regular coee brewing process. When nished also pour the leftover water in the
pod holder into the cup.
4. Measure the output and compare to the specications you nd on page 2.
5. Determine the deviation from the specication, the deviation can be adjusted in steps of 3,5 mL.
The calculated deviation divided by 3,5 will tell you how many steps (times you need to actuate the button) you need to
in-, or decrease the value.
6. Follow the steps as mentioned under Service modes - “Manual pump adjustment” to recalibrate the pump.
7. Measure the newly calibrated volume, and repeat steps 4-6 if necessary.
2-cup:
Repeat steps 1 to 7 to calibrate/adjust for the 2-cup recipe. (you can continue using the 1-cup podholder)
