When the ﬁlling 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 (25.6Khz) 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 overﬂow water level. (When this condition is detected, the machine will automatically starts draining water until the water level falls below the overﬂow water level)

Unbalance or cabinet bump is detected during ﬁnal 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.)

Door is detected as open when the motor is operating.

First check to see that all of water valves are not stuck. If water valves are OK, check water level sensor.

Go to “Wet Clothes” Troubleshooting Section.

Check all of keys. If A key is sensed to be pressed, all keys will do not respond.

Check for loose wire connections. Go to “Quick Test Mode” and then do Door lock/Unlock Test and Motor Test.

Test Mode:

Each Test Mode for the Squall 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.

Quick Test Mode

Deﬁnition of Quick Test Mode:

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

- Check model and software version.

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

How to Enter:

- Plug in the unit.

- Press Soil Level Key + Signal Key and Power Key at the same Time.

Important. Once test mode is performed, all data including the diagnostic code saved in the

EEPROM will be erased.

- Service Mode enables service technicians to verify the operation of the washing machine and do troubleshooting.

- Service Mode can be entered during all washing cycle without interrupting the cycle except some of test modes.

- Various tests can be done with Service Mode. So, troubleshooting can be done based on the resulting diagnostic codes.

How to Enter:

- To enter the Service Mode, press the Signal and Delay Start Keys for 3 seconds or until the unit sends out beeping sounds.

Service Mode:

1. The washer must be on to go into the Service Mode.

2. The motor speed will be displayed when started (It displays 0 when the motor does not spin).

3. The present state of the machine will not be changed.

(i.e., the current cycle in progress will not be interrupted and only the display will change)

4. To exit Service Mode, press Signal and Delay Start Keys for 3 second again, or Power Key.If no key is operated during Service Mode for 5 minutes, the machine will return to normal user mode.
