9. MAINTENANCE

Unless otherwise specifi ed, all maintenance operations
must be carried out when the machine is totally powered
down to OFF, it has cooled down and the mains socket is
unplugged. Use of metal, abrasive tools and solvents is not
recommended for machine cleaning operations:
they could all cause damages.
Where indicated, use specifi c detergents for coffee machi-
nes that are available on sale in the specialised technical
service centres.

9.1 Daily maintenance

For cleaning operations use cloths or sponges that will not release
fi bres or threads.
· Clean the bodywork accurately and, on the stainless stele parts,
rub in the direction of the satin fi nish.
· Clean the steam and the hot water dispenser pipes. Check to
see that the spout diffuser nozzles are not clogged or partially
clogged with crusts and residues. If a crust removal operation is
necessary, be very careful not to deform or damage the relative
sprayer.
· Remove the fi lter baskets from the machine. To remove any
grease deposits, rinse out the fi lters and fi lter baskets using
hot water.
