D. The steam nozzle (Fig 21 a, b)
This accessory consists of 2 parts: one part which is
the plastic support and the other which is the metal
protection cylinder.
• Before cleaning, unlock the nozzle from the
articulated arm by turning it to the left.
• Then slide the metal cylinder along the plastic
support.
• Clean these two parts with tap water and some
mild washing-up liquid.
• Rinse and dry.
• Once the parts have been properly cleaned, put the
metal cylinder back on the support.
• Make sure that you don't damage the silicone seal
which makes the nozzle watertight.
• Insert the nozzle on the articulated arm then twist
to the right.
10. 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
Av. number of Soft water
coffees per week (<19°th)
Less than 7 Once a year
From 7 to 20 Every 4 months Every 3 months Every 2 months
More than 20 Every 3 months Every 2 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.
