Descaling
Scale builds up inside the machine during use. It is essential
to descale the SENSEO
®
coffee 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 Use SENSEO
®
Descaler
(HD7012, HD7011, HD7006) only. It has been developed
to ensure better machine performance and operation.
Never use a descaling agent base on mineral acids such as
Sulphuric acid, Acetic acid (vinegar) or Hydrochloric acid.
These descaling agents may damage your SENSEO
®
coffee
machine.
For detailed instructions please refer to the Directions for
Use, Chapter Descaling.
Volume adjustment

the measurement.
5. Press the Normal coffee button once, to make a
