Machine prolonged stop
In case the machine is not used for some
weeks it is advisable to carry out an
accurate cleaning of all components inside
to avoid the formation of unpleasant
smells.
In case of a very long standstill, it is
advisable to oil the stainless steel surfaces
with white mineral oil.
HELPFUL SUGGESTIONS
MAINTENANCE
IMPORTANT: Before carrying out cleaning
and maintenance operations disconnect
the machine from the power supply source
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.
ACHIEVEMENTS
Any deficiency in the washing process is
apparent when dirty residuals are visible.
Any halos might be caused by an
insufficuent 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 temperatur 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.
SAFETY DEVICES
The dishwashers are equipped with a
number of devices in order to ensure the
safety of the operator and of the appliance
itself.
LIMIT MICROSWITCH
If dishes reach the end of the unloading
area, before the operator has managed to
unload the basket, the limit switch stops
the drawbar motion and therefore the
baskets.
DOOR MICROSWITCHES
Each inspection door is provided with two
safety microswitches forming two
redundant chains (safety level 2).
If one of the doors is opened accidentally,
the pumps, the conveyor belt gearmotor
and the rinsing area solenoid valve stop
working.
