SERVICE ACTIONS
F01
Main PCB, Triac
on board
damaged or
components
Feedback fault
- Check for water leaks that may affect connectors J009 (Commutator)
or J9 (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 efficiency of connector J001 (Commutator) or J010 (Three-
phase) on the PCB;
- Check connector J001 (Commutator) or J10 (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 (Commutator)
or J7 (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 J7 (three phase) /
Pressure switch;
- Disconnect appliance for 2 minutes. Check wiring and connectors 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.
F02
Motor tripped,
motor tacho
generator open
circuit or short
circuit
- Check for water leaks that may affect connector J009 causing the
contacts to short circuit;
- Check to ensure motor is not mechanically jammed or seized;
- Check efficiency of the contacts on connector J009 on the PCB;
- Check the motor side connector;
- Check motor winding and check that the impedance value on wiring
connector J009 between pins 3 and 4, 4 and 5, 3 and 5 is less than
100 Ohm; (three phase)
- Check the tacho generator winding and check that the impedance
value on wiring connector J009 between pins 1 and 2 is between 115
and 170 Ohm;
- Check the tacho generator wiring;
- Disconnect appliance for 2 minutes. Check that correct operation
has been restored by starting the Autotest routine;
- Renew motor;
- Renew PCB.
