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.

Disassembly- and Reassembly advice
2.3. Remove the housing.
To remove the housing, start at the front side of the housing and undo the clicks (1) on both sides.
Next undo the snaps on the back site of the housing (2), undo them with a athead screwdriver.
Make sure that none of the snaps snap back.
To avoid damaging the capacitor on the PCBA circuit be very gentle and start to remove the housing upwards rst lift
from position Afor approx. 1 or 2 cm and then gently lift the housing upwards in the direction of the arrow B.
But mind the 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.
Make sure before placing the housing part back, that the Hall sensor (WLI) cable is routed correctly.
Therefore when re-assembling, make sure the routing of the WLI cable is according the picture, see red arrows for
the attention points how to dress the cable.
Arrow Cmake sure the white NTC cable is pushed inside by the WLI sensor cable.
Place back the housing:
Gently place the housing downwards and make sure you rst click the snap locks on the front side housing position
(1) and then snap back the housing snaps on position (2).
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
starts ashing. 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.
Note: HD659x the descaling routine has changed to 2x descale cycles and 2x flushing cycles.
Intensity select
The new PCBA (03-2018 onwards) has an extra feature onboard “Intensity select”, which need to be enabled for the
following type numbers (HD6592 & HD6596).
Intensity select how does that work:
•Select the strong short coffee recipe by double tap on the 1-cups button for 1 cup of strong short coffee.
•Press the 1-cup button once for one large mild cup of coffee.
•Select the strong short coffee recipe by double tap on the 2-cups button for a double cup of strong short coffee.
•Press the 2-cup button once for two large mild cups of coffee.

Repair instruction
Selecting the right PCBA modus.
Enable/Disable the “Intensity select” feature.
The PCBA is standard delivered with the “Intensity select” feature disabled, this for easy servicing the existing SENSEO®
Switch HD7892/xx /G range with plastic OPR Boiler installed.
The “Intensity select” function can be simple enabled/disabled:
1. Keep the 1-cup and 2-cup button pressed while connecting the appliance to the mains.
2. Release the buttons when the 1-cup and 2-cup LEDs have switched on.
3. Press and release the 1-cup and 2-cup button at the same time, the 1-cup and 2-cup LEDs blink rapidly 3 times.
4. Repeat step 3 once more.
5. Depending if the “intensity select” feature is enabled or disabled the 1-cup or 2-cup LED is switched on.
See table below:
Intensity select disabled
(HD7892 & HD6591) 1-cup LED is on 2-cup LED is o
Intensity select enabled
(HD6592 & HD6596) 1-cup LED is o 2-cup LED is on
6. Press the desired button following the table for the desired state the appliance should be in.
7. Press and release the 1-cup and 2-cup button at the same time to store the value, the 1-cup and 2-cup LEDs blink
rapidly 3 times.
8. If the “Intensity selection” is disabled (1-cup LED) has being selected in step 6 LED’s will switch o.
If the “Intensity selection” is enabled (2-cup LED) has being selected.
Press and release the 1-cup and 2-cup button at the same time once more, the 1-cup and 2-cup LEDs blink
rapidly 3 times.
Volume adjustment
Note: Volume adjustment may only be carried out in case 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.
If the Intensity selection is enabled, also make sure to adjust the scale factor.
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 properly lled; 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 are 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 table “Water specication” you nd on page 2.
5. Determine the deviation from the specication if any, 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 memory 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)
