The water level fails to drop below the Reset Water Level within 15 minutes.

Door fails to Unlock After 7 attempts.

When the lling Continues for more than 40 minutes or there is no change of water level for 6 minutes.

Door fails to lock after 7 attempts.

A water level lower than the Reset water level is detected for 5 seconds during the Wash/Rinse cycle.

Water Level Sensor Trouble. (When the input signal from the water level sensor is out of range, the unit will send out beeping sounds and halts the cycle.)

A fault is detected in the water level sensor. Data (frequency) shows the water level is at or above the overow water level. (When this condition is detected, the machine will automatically starts draining water until the water level falls below the reset water level)

Unbalance or cabinet bump is detected during nal spin, which prevents the drum from spinning over 150 rpm. (Never exceeds 150 RPM due to unbalanced load)

Jammed Key.(When key input signals are coming out for more than 30 seconds, it is regarded as a jam.)

System Error Replace PCB

Go to “Quick Test Mode” and then do Door Lock/Unlock Test

Go to “ Board Input Test” and check Water Temperature. Check loose or pinched wires. Replace PCB or thermistor.

Evaluate wire harness for loose or unhooked connections. Go to “ Quick Test Mode” and test Motor.

Replace PCB

Please connect the hot/cold water hose connection correctly.

Test Mode:

Each Test Mode for the BIGBANG is as follows in the coming pages. The test modes indicated by the red arrows are modes unable to get an access once the washing cycle has started due to safety resons.

Denition of Quick Test Mode:

- Check operation of all LED’s (Verify faulty LED).

- Check model and software version.

- Check dierent operating modes (e.g. water valve, motor, door, drain pump, etc.).

How to Enter:

Quick Test Mode:

1. All LED’s light up and it sends out Beep Sound when it

enters into the Quick Test Mode. (Including 7-Segment)

2. Displays software version for a sec and Clear EEprom. (Ex. If S/W Version is 49, 7-Segment will display dE49)

3. When the version is displayed, turn the Jog-Dial so that the version disappears. Press the following keys to test the various components.

- Temp Key : Water Valve Test

- Spin Key : Door Lock/Unlock Test

- Soil Key : Water Heater Test

- Signal : Drain Pump Test

EEPROM Clear Check

Denition of EEPROM Clear Mode:

- EEPROM initialization.

- All course/option settings are to be reset to default values after EEPROM initialization.

- When Service arises and it needs PCB replacement, EEPROM should be reset.

How to Enter:

- The unit needs to be on.
