- It prevents malfunctioningIf the descaling procedure is not performed correctly, scale residue remainsbehind in the machine. This causes scale to build up more quickly and maycause permanent and irreparable damage to the machine.use the correct descaling agentOnly citric acid-based descalers are suitable for descaling the SENSEO ®machine. This type of descaler descales the appliance without damagingit. For the correct amount, see under ‘Descaling procedure’ below. Eachdescaling mixture can be used only once. After use, the descaling mixture isno longer active.We advise you to use the special SENSEO® Descaler (HD7006). Read theinstructions on the package of the descaling agent.Never use a descaling agent based on mineral acids such as sulphuricacid, hydrochloric acid, sulphamic acid and acetic acid (e.g. vinegar). Thesedescaling agents may damage your SENSEO® coffee machine.Descaling procedure1 Mix 50 grams of citric acid with 1 litre of water in a measuring jug.Stir until the powder is completely dissolved.2 Fill the water reservoir up to the MAX indication with the descalermixture. Then put the water reservoir back into the coffee machine.Note: Not all SENSEO® machine types have a water reservoir with a capacityof 1 litre. If you have a SENSEO® machine with a smaller water reservoir,repeat steps 2 to 6 with the remainder of the mixture without filling the waterreservoir up to the MAX indication.3 Press the on/off button 3.The machine is ready for use when the indicator light lights up continuously.4 Place the 1-cup pod holder q with a used coffee pod in it in thecoffee machine. Close the lid and make sure it is properly locked.Note: Always put a used coffee pod in the pod holder when you descale themachine.This pod serves as a ‘filter’ to prevent the sieve or hole in the podholder from getting clogged with scale residue.5 Put a bowl with a capacity of at least 1500ml under the spout tocollect the descaling mixture.6 Press the 2-cup button qq and let the machine operate. Repeat thisuntil the water reservoir is empty.Never interrupt the descaling process!7 Repeat steps 1 to 6. Replace the used pod with another used pod tofilter out the scale residue.Note:To descale properly, you have to use 2 litres of descaling mixture.Never descale the SENSEO ® coffee machine with the lid open. Make surethe lid is properly locked.EnglisH16
