MAINTENANCE AND
PROVISION OF SPARE
PARTS
8.1 TROUBLESHOOTING
INSTRUCTIONS
a) The machine will heat irregularly.
1) it will not heat
Make sure that power input is uniform in the
three phases. Check that the probe of the
electronic thermostat is fastened correctly
and that contactor (C1) is in good working
order.
2) it will heat too much
Again, check that the probe of the electronic
thermostat is fastened correctly and the air
slots on the basin housing are clean.
b) The basin will not go up or down
1) It will not go up:
Take off the left side panel and check that
the brass screw is in perfect condition.
2) it will not go down
Take off the left side panel and check that
the brass screw is in perfect condition.
c) The machine is very noisy
One of the three input phases is certainly cut
and the overload cutout switches
consequently keep being actuated (the
YELLOW pilot light goes on and the
machine is stopped). The automatic cutout
switch on the wall may be faulty. Otherwise
one of the three fuses on the built-in cutout
switch may be blown. Work out the source
problem and replace the cutout switch or the
blown fuse accordingly.
d) The cotton sheet deteriorates quickly
1) Again, check that the probe of the
electronic thermostat is fastened correctly
and the air slots on the basin housing are
clean.
Make sure that the distance between the
machine and the wall is correct and enables
correct ventilation. Damage to the cotton
sheet may otherwise follow.
2) Iron on the whole length of the roller
according to the instructions of section 7.
e) The pressure of the roller is uneven.
Make sure that the gas springs are in good
working order as follows: lower the basin
and check that the movement arms are not
loose. Otherwise put the basin at rest,
unscrew the bolts bearing the springs and
replace them. Replace both springs to avoid
irregular basin pressure.
f) The automatic cutout switch on the
wall is triggered now and again.
The appliance is equipped with electronic
devices that provide the means for the
interference filter. However, the use of the
filter entails a current leakage to earth of
5÷8 mA. If similar appliances are connected
to the same line, the threshold of the cutout
switch may be exceeded (as a rule 30 mA).
If so, then install one cutout switch for each
appliance.
g) The machine does not suck moisture
from the clothes
Every 600 operating hours clean the air-
expeller system as follows: put the wall and
built-in cutout switches off and remove the
left side fairing panel. Then take the silicone
tube off after having loosened the strips that
lock it in place and clean it using a cloth and
a vacuum-cleaner. By the use of a
screwdriver remove the screws fastening
the tube to the scroll of the air expeller and
clean the fan by the use of a powerful
vacuum-cleaner.
h) Replacement and control of fuses
The machine is fitted with n. 5 fuses divided
as follows:
Three power fuses,
Model Voltage Fuses
160 400V 20A
160 230V 32A
200 400V 25A
200 230V 40A
Two fuses protecting the control circuit,
which are located on the control board and
are marked with the initials F1 - F2. Both are
4A, no matter the model and the power
voltage.
Prior to starting the machine after the
actuation of a safety device, work out the
cause of the fault. Further damage to the
appliance may otherwise be entailed.
8.2. SAFETY DEVICES
The machine features an electronic control
system that governs ordinary functions and
monitors some of the main settings of the
machine.
Apart from such electronic safety devices,
the appliance is also equipped with
electromechanical safety systems that
provide a high protection degree even in
case of failure of the electronic control.
The settings monitored by the machine,
which are indicated by flashing initials are
as follows:
"AL1" SUPERTEMPERATURE OR
FAULTY PROBE
When a temperature beyond 210°C is read
or when the probe is out of order this alarm
message is displayed and an intermittent
whistle-like sound is emitted for one
minute. The appliance remains like that,
still on but under alarm, until the
temperature drops below the alarm
threshold. To eliminate this problem it is
also possible to switch the appliance off and
then on again.
"AL2" THE OVERLOAD CUTOUT AT
THE EXTRACTION SYSTEM HAS
TRIPPED
16
When malfunction or overheating is
detected in the extracting motor this alarm
message is displayed and an intermittent
whistle-like sound is emitted for one
minute. The machine is automatically
switched off and the ironing basin is lifted to
its rest position. This alarm can eliminated
only by repairing and if need be replacing
the extracting system.
"AL3" BASIN MOTOR OVERLOAD
PROTECTION
If the basin motor runs irregularly, this
alarm trips, accompanied by the buzzer. As
a consequence the machine is turned off and
the basin is not brought to its rest position.
Lift the basin to idle position using the
apposite wheel.
To cancel this alarm, reset the appliance
(switch it off and then on again).
"AL4" THE OVERLOAD CUTOUT AT
THE ROLLER MOTOR HAS TRIPPED
When malfunction is detected in the roller
motor this alarm message is displayed and
the alarm buzzer is actuated. The machine is
automatically switched off and the basin is
brought to its rest position. To eliminate this
problem switch the appliance off and then
on again.
"AL5" SAFETY DOOR
If the safety door is opened when the
appliance is on, this flashing message is
displayed. The machine is automatically
switched off but the basin is NOT brought to
its resting position. To exit this alarm status
just put the safety lid back in its normal
position. The position of the safety door is
monitored also when the machine is not
working but it is being energised (only
yellow light on).
"AL6" BASIN UP TIME OUT
If after the pedal has been pressed the basin
does not reach its resting position within 10
seconds, this alarm message is displayed
and the alarm buzzer is actuated. The
appliance is automatically switched off and
only by being switched on again will it exit
this alarm status.
FURTHER SAFETY DEVICES
Apart from the electronically controlled
safety systems, the appliance is equipped
with a number of electromechanical
protection devices, i.e.:
1) SAFETY THERMOSTAT, manual reset
type, located at the rear of the machine, on
the control panel side. It cuts off power to
the heating elements as soon as temperature
reaches beyond 220°C. To reset the safety
thermostat unscrew its cap and press the
black pin with a tool until a "click" is heard.
Then screw the cap back in place. Find out
what the cause of overheating was.
