b) Descaling the Machine
Depending on the hardness of the water and the frequency of use it is possible that the pipes
will block progressively depending on the lime scale content in the water. This is noticeable
when the filtering process takes longer than normal. To prevent this follow the procedure
below:
Fill the tank with one third vinegar and two thirds water.
Plug in the coffee maker and start it.
After 30 seconds turn the machine off.
Wait for 30 minutes to let the vinegar work and then turn the machine on again.
Once the coffee preparation cycle has finished, turn off the coffee maker.
Repeat this operation two or three times depending on the amount of scale.
After descaling the coffee maker operate it 2 or 3 times with just water to remove the
vinegar residues.
The frequency of descaling depends on the type of water which you use to make the coffee:
soft water: every 6 months
normal water: every 2/3 months
hard water: every 6 to 8 weeks
