10. MAINTENANCE

Maintenance operations have to be carried

out when the machine is off and cold and the

plug is disconnected. Some particular ope-

rations have to be effected when the machine

is operating.

Do not clean the machine by using metal or

abrasive devices, such as steel wool, metal

brushes, needles, etc. or general detergents

(alcohol, solvents, etc.)

When necessary, use special detergents for

coffee machines that can be bought in spe-

cialized service centres.

Use a clean cloth or sponge that does not leave hairs

or fluff (preferably cotton or linen).

● Carefully clean the outside surface, following the

grain of the satin finish on the parts in stainless

steel.

● Clean the steam and hot water spouts and check

that the nozzles are not encrusted (if they become

encrusted, be careful not to deform or damage

them).

● Clean the spray units and the seals under the ca-

sing of the delivery units using the special brush

supplied.

● Remove the filter-holders and remove the filter and

the clamp which secures the filter, use a brush to

remove any coffee deposits and rinse with hot water

in order to dissolve any grease deposits.
