ERROR CODES & FAULT FINDING
IMPORTANT NOTE: Disconnect the machine from Electricity Supply before any testing.

General Information

If the machine has an Earth Fault it can display erroneous fault codes.
Repair any Earth Faults on the machine before using the code guide on the previous page.
Some faults will not show up as error codes:-
The module will not show up a fault if the water to the machine is turned off or if the solenoid
valves are open circuit.
Certain motor faults, will not show as a fault, the door will lock but the machine will not start a
programme. (motor plug disconnected, faulty brushes etc.)
Open circuit field windings will signal fault F01.
If the motor Thermoprotector (toc) - if fitted - operates in the middle of a cycle, the machine will
stop with no fault code indicated, when the thermoprotector (toc) resets the cycle will then restart.
If the element goes open circuit in the middle of a programme and the pressure switch is in the full
position, the machine may not signal a fault but will wash for a long extended period.

models. Refer to text for appropriate information.Note: This chart refers to both "commutator"
(brush motor) and "three phase" (non-brush motor) models. Refer to text for appropriate

SERVICE ACTIONS
- Check for water leaks that may affect connectors J009 (Commuta-
tor) or J009 (Three-phase) causing the relative contacts to short;
- Check the motor terminal board (any problems due to aggression
caused by manufacturing chemical residues that may cause
short circuits);
- Check the connection on the wash heating element;
- Check effi ciency of connector J001 (Commutator) or J010
(Three-phase) on the PCB;
- Check connector J001 (Commutator) or J010 (Three-phase)
pins 3 and 4 for continuity of the wash heating element (1700
watt - 230 volt) which must be 30 Ohm +/- 10%. Otherwise,
renew heating element;
- Check for water leaks that may affect connectors J006 (Commuta-
tor) or J007 (Three-phase) causing the relative contacts to short;
- Check the terminal board (any problems due to aggression
caused by manufacturing chemical residues that may cause
short circuits);
- Check wiring of connectors J006 (Commutator) or J007 (Three-
phase)/Pressure switch;
- Disconnect appliance for 2 minutes. Check wiring and connec-
tors of the dryer heating element on main PCB board side and
component side;
- Check that correct operation has been restored by starting the
Autotest routine;
- Renew main PCB.
- Check for water leaks that may affect connector J9 causing the
contacts to short circuit;
- Check to ensure motor is not mechanically jammed or seized;
- Check effi ciency of the contacts on connector J9 on the PCB;
- Check the motor side connector;
- Check motor winding and check that the impedance value on
wiring connector J9 between pins 3 and 4, 4 and 5, 3 and 5 is
less than 100 Ohm;
- Check the tachogenerator winding and check that the impedance
value on wiring connector J9 between pins 1 and 2 is between
115 and 170 Ohm;
- Check the tachogenerator wiring;
- Disconnect appliance for 2 minutes. Check that correct operation
has been restored by starting the Autotest routine;
- Renew motor;
- Renew PCB.
- Check effi ciency of contacts on connector J005 (commutator)
or J12 (three-phase) on PCB;
- Check NTC ensuring that the impedance value at ambient
temperature (20°C) on wiring connector J005 (commutator) or
J12 (three-phase), pins 1 and 2, is approximately 20 KOhm;
- If measurement is incorrect check continuity of wiring J005
(commutator) or J12 (three-phase), pins 1 and 2/NTC;
- Check the same parameter directly on the NTC (20 KOhm);
- Renew NTC;
- Renew PCB.
