Descaling procedure
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: Not all SENSEO ® machine types have a water reservoir with a capacity
of 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 water
reservoir up to the MAX indication.
3 Press on/off button I.
The machine is ready for use when the indicator light lights up continuously.
4 Place the 1-cup holder ° with a used coffee pod in it in the coffee
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 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 descaling mixture.
6 Press the 2-cup button °° and let the machine operate. Repeat
this until the water reservoir is empty.
Never interrupt the descaling process!
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 descaling mixture.
Never descale the SENSEO ® coffee machine with the lid open. Make
sure the lid is properly locked.
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
descaling 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 pad and clean the pod holder after descaling to
prevent the sieve or hole in the centre from getting clogged.
