REPAIR INSTRUCTION

Descaling
Scale builds up inside the machine during use. It is essential to descale the SENSEO
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
For detailed instructions please refer to the Directions For Use, chapter CALC.

the LED starts fl ashing quickly. Once the appliance is heated up, it starts making the coffee, press the button again once the
desired volume is reached. The LED will blink rapidly as confi rmation the volume has been stored.
To reset the user programmable volumes to default (60 mL Strong coffee, 125 mL Regular coffee), keep both buttons pressed,

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.
For the correct procedure on Volume measurement, please refer to the Senseo Repair process.

in the pod holder into the cup.
5. Measure the output and compare to the specifi cations on P.X
6. Determine the deviation from the specifi cation, the deviation van be adjusted in steps of 3,5 mL. The calculated
deviation divided by 3,5 will tell you how many steps you need to in-, or decrease.
7. Follow the steps as mentioned under Service modes - Manual pump calibration to recalibrate the pump.
