The models equipped with LCD and DIGIT interface allows to read the code of the fault occurred in the
washing machine on the display (example: F-08).
FAULT
F01
Motor piloting triac short

Motor blocked, motor tacho
F02
open / short circuited
Wash NTC probe open /

overflow. The drain pump is
automatically activated by
the overflow contact.

CAUSE
- Check eventual leaks of water which may involve the J9 connector,
short-circuiting its contacts;
- Check motor terminal board (problem caused by the eventual ag-
gression of working - chemical residues, which may produce a s.c.);
- Replace the board
- Verify if the motor is blocked;
- Check the tacho winding verifying that on J9 wiring connector between
the pins 1 and 2 is shown a resistance value included between 115 and
170 . In case of s.c. or open contact, check the wiring between the
pins 1 and 2 of J9 relative to the tacho. In case of a tri-phase motor,
verify that between the pins 6 and 7 of J9 there is ohm-continuity;
- Replace motor;
- Replace board
- Check the efficiency of the contacts of J3 connector on the board;
- Check the state of the pressure switch verifying ohm-continuity on
J3 wiring connector, pins 2 and 4 (only with empty tank) and pins 2
and 1 (only with water in the tank, over half door glass level);
- Check wiring of J3 connector/pressure switch;
- Replace pressure switch;
- Replace board.
- Check the efficiency of the contacts of J9 on the board, verifying that
between pins 8 and 9 the tension is 220 V;
- Verify that the pump is supplied;
- Check pump filter + wall-drain;
- Replace pump;
- Replace board.
- Check the efficiency of the contacts of J8 connector on the board;
- Check NTC verifying that on J8 wiring connector, pins 11 and 12 the
resistance value at room temperature is about 20 k ;
- If the measure is wrong, check wiring continuity J8/NTC. Check di-
rectly on NTC this same parameter.
- Replace NTC;
- Replace board.
- Check the efficiency of the contacts of J3 connector on the board;
- Check on J3 connector, pins 5 and 6 the continuity of the wash heater.
The heater is of 1800W 230V and has a value of 25 ;
- Check pressure switch, connector J3 pins 2 and 3: there must be no
ohm-continuity (main contact with "full");
- Check pressure switch, connector J3 pins 2 and 3: there must be
ohm-continuity;
- Replace pressure switch;
- Replace heater
- Replace board
