Descaling your SENSEO® appliance


When to descale

After you have brewed 500 cups, the CALC CLEAN indication appears on the display. Always descale when this indication appears.
After you have brewed another 8 cups, the CALC CLEAN indication disappears from the display, whether or not you have performed the descaling procedure.
It is essential to descale the SENSEO® coffee machine at least every 3 months, but not more than 6 times a year.

How to descale

1. 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 descaler mixture. Then put the water reservoir back into the coffee machine.

Note: If you use a citric acid-based liquid descaler, follow the instructions on the bottle.

Note: Not all SENSEO® machine types have a water reservoir with a capacity of 1 litre. If you have SENSEO® machine with a smaller water reservoir, repeat steps 2 to 6 with the remainder of the descaler mixture without filling the water reservoir up to the MAX indication.

4. Place the 1-cup pod holder with a used coffee pod in it in the coffee machine. Close the lid and make sure it is properly locked.

Warning: Never descale the SENSEO® coffee machine with the lid open. Make sure the lid is Properly locked.

Note: Always put a used coffee pod in the pod holder when you descale the machine. This pod serves as a 'filter' to prevent the sieve or hole in the pod holder from getting clogged with scale residue.

5. Put a bowl with a capacity of at least 1500ml under the spout to collect the descaler mixture. descaling step 5


6. Press the 2-cup button and let the machine operate. Repeat this until the water reservoir is empty.
Warning: Never descale the SENSEO® coffee machine with the lid open. Make sure the lid is Properly locked.

descaling step 6

7. Repeat steps 1 to 6. Replace the used pod with another used pod to filter out the scale residue.
Note: To descale properly, you have to use 2 litres of descaler mixture.

8. Rinse the water reservoir with tap water. Fill the water reservoir up to the MAX indication with tap water and repeat steps 3 to 6.
Note: Do not refill the water reservoir with used hot water or the used descaler mixture.

9. Fill the water reservoir with fresh tap water up to the MAX indication again and repeat steps 3 to 6 once more.
Note: Always rinse the machine by letting it empty two full water reservoirs.

10. Remove the used pod and clean the pod holder after descaler to prevent the sieve or hole in the centre from getting clogged.
