CANDY WASHING MACHINES
- "OPTIMA" SERIES WITH "EASY" ELECTRONICS:
SELF-DIAGNOSTIC CHECKING ROUTINE AND ERROR CODES.
1)
PRELIMINARY OPERATIONS TO THE AUTO-TEST CHECKING ROUTINE:
Connect a
20A/AC reading scale
2 digits Digital Ammeter, in series to one of the phases of
the mains current, on the mains wire of the appliance.
What
above
will
allow
the
check
of
the
good
functionality
of
the
electromechanical
components, when fed during the carrying out of the Auto-test sequence.
Carefully empty the drum of the washing machine, because during the carrying out of the
Auto-test
sequence,
the
anti-unbalancement
safety
usually
provided
by
the
software
is
disabled.
Set the Program Selector's Knob
(Ref.
2 in Picture
1)
on the OFF position.
2)
ACTIVATION OF THE SELF-DIAGNOSTIC ROUTINE:
1

Push and hold the FIRST Option Button with LED top right
(ref.
1 in Picture
1).
Turn the Program's Selector Knob
2 steps in clockwise sense
(ref.
2 in Picture
1).
After about
5 seconds, release the FIRST Option Button with LED to the left
( ref.
1
in Picture
1).
If
the
previous
procedure
was
correctly
carried
out,
all
LEDs
are
turned
ON
simultaneously
(see Picture

DESCRIPTION OF THE SEQUENCE OF SELF-DIAGNOSTIC ROUTINE:
Water
is
loaded
to
fulfill
the
"basic"
level
of
6
liters,
through
the
Detergent's
Compartment for Pre-wash
(I) .
1 second of pause .
It's
now
fed
for
20
seconds,
the
Water
Heating
Element
(~8
A
on
the
Digital
Ammeter).
Timed water load is carried out through the Detergent's Compartment for Main Wash
(II) .
It's
fed the Motor for the tumbling of the Drum in Anticlockwise sense at
55 rpm
and for the time of
~
16 seconds.
Pause
of
the
Motor
for
~
4
seconds.
The
timed
water
load
continues,
as
in
the
previous paragraph.

Are
simultaneously
fed
the
Solenoid
Valve
for
Water
Load
through
the
Washing
Compartment
(II)
and the Motor for the tumbling of the Drum in Clockwise sense at
55 rpm , for the time of
~
12 seconds.
In the last seconds of this phase, the timed water load is done with the simultaneous
feeding
of
both Solenoid
Valves,
to
end it
trough
the
Detergent's
Compartment for
Softener
( U ) .
It's
fed the Drain Pump , until "empty tank" Pressostat's condition.
It's
carried out a Short Spin Phase, lasting
~
15 seconds , at the half of the maximum
speed available and then the Self-diagnostic sequence is ended.
At
the
end of the sequence of Auto-test,
all
LEDs that
were turned ON during the
Self Diagnosis, will flash together .
4) DISPLAYING OF THE ERROR CODES:
Same as it happens for all electronically
controlled
Washing Machines produced by the
Candy
Group,
all
appliances
of
the
"OPTIMA"
series
are
equipped
with
an
advanced
software,
capable
of
immediately
recognizing
the
presence
of
the
most
serious
functional troubles.
In such a case, the currently carried out
washing cycle is halted and the Control
Panel
displays
the
related
Error
Code.
The Error Code is displayed through the
FLASHING
of
the
FIRST
OPTION
LED
TOP RIGHT . The LED flashes a number
of
times
corresponding
to
the
ERROR
NUMBER, then stays OFF for
5
seconds
and the sequence is repeated, until the
next User's intervention:

In case an Error Code is displayed and the machine is halted. To restart the machine it's
necessary to move the Program's Selector Knob to the OFF position. Then, if water is still
present
in
the
tank,
select
the
"DRAIN"
position
and
wait
for
the
drain
phase
to
be
ended. Eventually move the Program's Selector to OFF. Wait for
2
seconds and select a
new washing program.
If
the
previously
found
trouble
should
now be missing,
the
set
washing cycle is carried out to it's natural ending. On the contrary, the same Error Code
as previous
(or a different one) will be displayed, and the Machine is halted.
Making reference to the above resuming table of the available Error
Codes, we like to
remind the importance of the perfect continuity of the electric wiring and of the related
connectors, when dealing with electronic controls of the "Core" family. This is both true
for
the
contacts
on
the
Control
Board
then
for
the
corresponding
contacts
on
the
controlled
peripherals
(Program's
Selector,
Display
Board,
Drain
Pump etc.).
A partial
oxidation of some connector's contacts on the "Core" Control Board or on the connected
peripherals, could generate the displaying of a peripheral related Error Code, even being
the involved peripheral in perfect conditions.
Therefore, we suggest to carefully check the related wiring, before any replacement of
the
"Core"
Control
Board
and
before
replacing
any
of
the
related
peripherals.
A valid
check of
the
wiring
can be performed by removing the connectors from their
location
(both
on the Control
Board then on the related
Peripheral)
and by spraying
inside
the
same connectors a small amount of Contact Cleaner liquid. Then, re-fit the connector in
position
and
re-start
the
Auto-test
routine,
to
see
if
the
Error
Warning
is
displayed
again.
