The digits indicate the water level frequency.
For example, if 25 is displayed

1. Range of vibraiton sensor data has to

change between 1900 and 2100 when
stopping the motor.

2. When the washer is in spin mode, if the

vibration sensor data doesn’t change
and keeps the static value, disconnection
or noise effect is suspected.

3. In case of over-range, we also need to

check the status of vibration sensor.

1) Data View Type : Touch and Hold Pre Wash and Temp. key simultaneously, and then turn the knob

until it display ‘043’.

2) Vibration Sensor Data = Vib_Sensor X-axis_01 x 100 + Vib_Sensor X-axis_02
3) Vibration Sensor status : If it displays ‘000’, normal, ‘001’, incorrect initial position of vibration sensor

or offset error, ‘002’, disconnection of vibration sensor.
