Indesit Ariston AQUALTIS 1600 Service Manual page 22

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
circuited
Motor blocked, motor tacho
F02
open / short circuited
Wash NTC probe open /
shor t circuited or wash
F03
heater relay welded (sig-
nalled with full pressure
switch)

overflow simultaneously. If
pressure switch contact is
fixed on "empty", the WM
F04
fills water up to reach the
overflow. The drain pump is
automatically activated by
the overflow contact.
"Empty" pressure switch
F05
not reached.
No absorption of the wash
heater (signalled only by
F07
"empty" pressure switch).

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
