8. DESCALING
■ Regular descaling of your appliance, as mentioned in paragraphs A and B for the coffee and steam
functions, is the best guarantee of your machine's long life. The frequency of the descaling operations
must be adapted to suit the hardness of your water. Ask for advice from your local water authority.
■ During the operation, do not stand your appliance on a marble surface. The descaler could affect it.
■ To make this clearer, please find below a summary table of the frequencies of the descaling operations
according to the hardness of water and use:
DESCALING FREQUENCY
Ave. number Soft water
coffees per week (<19°th)
Less than 7 Once a year
From 7 to 20 Every 4 months
Over 20 Every 3 months
If in doubt, we recommend carrying out a descaling operation every month.
No repairs to your machine will be carried out due to:
- descaling not being carried out,
- scale.
