8.6 - HELPFUL SUGGESTIONS
MAINTENANCE
IMPORTANT: Before carrying out cleaning
and maintenance operations disconnect

by means of the wall-mounted switch or by
means of the disconnecting switch located
on the control panel.
WARNING! - Do not disconnect the
switch when the machine is on!
Check and frequently clean the nozzles.
The frequency at which such operation
shall be carried out will be suggested by
the quantity of residues and scales and by
the unsatisfying washing results.
To clean the machine outside and inside,
never make use of corrosive products such
as sodium hypochlorite (bleach) and
hydrochloric acid (muriatic acid), acids in
general, wire wool and steel brushes.
To avoid compromising the correct
operation and to keep the appliance in
optimal hygienic conditions, it is advisable
to carry out periodical sanifications and
scale removing operations.

apparent when dirty residuals are visible.
Any halos might be caused by an
insufficient rinsing: in this case, check that
the rinsing jets are clean and there is a
sufficient pressure in the water distribution
network (2÷4 bar) ;
In the case that residuals are present,
check that:
• the washing jets are clean
• pre-washing temperature is 40 °C
maximum;
• washing temperature is from 55 to 60 °C,
• rinsing temperature is from 80 to 85 °C,
• there is detergent in the right
concentration;
• the filters are clean;
• washing water is not dirty;
• the positions of the objects in the rack
are correct.
