4.3. FAULT ANALISYS AND SOLUTIONS:

On Time washing machine warns the user of the presence of a fault by a quick flashing of the DOOR LOCK

LED, but its control panel does not display the fault code.

To read the fault code it is necessary to start Auto Test, using the hardware key which visualizes the fault

code.

The Faults are the same of the EVO II.

FAULT

F01

Motor piloting triac short-

circuited

Motor blocked, motor tacho

F02

open /short-circuited

Wash NTC probe open/

short-circuited, or wash-

F03

heater relay welded (sig-

nalled in "full" position)

Simultaneous presence of

"empty" + overflow. If pres-

sure switch contact is fixed

on "empty", the WM fills wa-

F04

ter up to reach the overflow.

The drain pump is auto-

matically activated by the

overflow contact.

"Empty" pressure switch

F05

not reached

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 be-

tween the pins 1 and 2 is shown a resistance value included be-

tween 115 and 170

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 J8 connector on the board;

- Check NTC verifying that on J8 wiring wash 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 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.
