CLEANING
1. Do not forget to remove the plug from the socket and make sure the appliance has
cooled down before cleaning.
2. Never immerse the cord, plug, or appliance itself in water.
3. Wipe outside with soft, moist cloth when the appliance has cooled down completely,
never use metal polish.
4. Clean the permanent filter (if applicable) and other detachable parts in warm soapy
water, rinse with fresh water and dry them before reassembling.
5. Clean the inside of jug with a soft brush in warm soapy water. Rinse with fresh water
and dry it before next use.
Note: Never use a dishwasher to clean the jug.
6. Clean the appliance at least once every 3 months so as to keep high efficiency.
7. Store the appliance in a dry and not very hot place.
DESCALING
The appliance has to be descaled regularly, otherwise the coffee taste will become bad
and the scale deposited inside in the machine may cause permanent and irreparable dam-
age to the machine.
If you begin to notice an increase of noise during boiling, or a longer brewing time, or
the appliance switches off before the water tank is empty, this indicates that descaling is
necessary.
The frequency depends on the water hardness and the brewing frequency. Generally, the
descaling should be done in the following periodicity:
• With soft water, at least once every 3 months.
• With hard water, at least once every month.
If doubt to the water hardness, ask advice of your local tap water company.
It is recommended to use only liquid descaler suitable for coffee maker, and read carefully
the instructions on its package or user manual before use.
1. Mix adequate descaler with cold water in a measuring jug.
Note: Never use a powder descaler.
2. Fill the water tank up to the max. level with prepared solution.
3. Operate the appliance until the water tank is empty as if you brewed coffee, but
without paper filter and ground coffee in the filter holder.
4. Repeat steps 1 to 3 for another descaling cycle.
Note: Never refill the water tank with the used descaling solution because it is no
longer active.
5. Operate two more brewing cycles with fresh, cold water to remove all descaler solu-
tion residues.
Important:
a. Never interrupt the descaling process.
b. Malfunctions caused by scale deposited inside the appliance are not covered
by the guarantee if the descaling process is not carried out properly.
