Flash Functional Test Program
Entrance to the test mode:
1. Turn off the machine from On/Off Button
2. Turn on the W/M from the main switch, while pressing “start/pause/cancel” button and the selected program is cotton
90. Start icon will start to blink within 3 seconds. At the moment, you can see the code of failure in follower LEDs or on 7
segment.
3. After seeing the failure, erase the failure by pressing start/pause/cancel button 3 seconds without losing any time
4. After erasing the failure code, you will be in functional test mode. Each push to the start / pause / cancel button will
represent one function.
Functional Test Sequence:
1. All LEDs on the board will start to blink after the door is locked.
2. Take in water from pre-wash compartment
3. Take in water from main wash compartment
4. Take in water from softener compartment
5. Take in water from main wash compartment if the W/M has a hot valve option (If not this step will be skipped)
6. The heater will be ON. If the water level inside the tub is not enough for the heater to switch on then all valves will be
turn on to fill the level.
7. Clockwise motor rotation with 52 rpm
8. Counterclockwise motor rotation with 52 rpm
9. Draining
10.Spinning up to maximum speed.
11. Turn on all the valves to fill a certain level in a short time for water leakage test on the production line.
12. End
13. You can get off the test mode by turning the WM off.Faults:-
H1 : NTC OPEN CIRCUIT OR SHORT CIRCUIT ( 10000 )
H2 : HEATER OPEN CIRCUIT ( 01000 )
H3 : HEATER ALWAYS ON ( 11000 )
H4 : VALVE TRIAC SHORT CIRCUIT ( 00100 )
H5 : PUMP OPEN CIRCUIT ( 10100 )
H6 : MOTOR TRIAC SHORT CIRCUIT ( 01100 )
H7 : PRESSURE SENSOR FAILURE ( 11100 )
H11 : MOTOR / TACHO OPEN CIRCUIT ( 00110 )Help:-
Not able to select any program ( As warning softener led blinks in program follower ) IF Yes:- Check program selector resistance and compare
the value with the table:-1. Position ~1 Kohm
2. Position ~2 Kohm
3. Position ~3 Kohm
4. Position ~ 4Kohm
5. Position ~ 5Kohm
6. Position ~6 Kohm
7. Position ~7 Kohm
8. Position ~8 Kohm
9. Position ~9 Kohm
10. Position ~10 Kohm
11. Position ~11 Kohm
12. Position ~12 Kohm
13. Position ~13 Kohm
14. Position ~14 Kohm
15. Position ~15 Kohm
16. Position 16 Kohm
If All the resistance values ok:- Check connection between program selector and main board. If there is not problem at connection change the Main PCB.
program selector and main board.If All the resistance values not ok:- Change the program selector
Is RINSE led blinking in the program follower ? If Yes:- Check Valves/ Voltage to valves/ Water supply to valves.
Is MAINWASH led blinking in the program follower? If Yes:- While programming card, an error may be occurred in one of the processing stages,
change the Main PCB.) -
