Data View Type : In case of ‘040’

1. Range of vibraiton sensor data have to

change between 1900 and 2100 in

stopping the motor.

2. When the washer is spining, if the vibration

sensor data doesn’t change and keeps the

static value, we need to suspect

disconnection or noise effect.

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

check the status of vibration sensor.

1) Data View Type : Press and Hold Pre Wash and Temp key simultaneously, and then turn around 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 display ‘000’, normal, ‘001’ incorrect initial position of vibration sensor or

offset error, 002 disconnection of vibration sensor.

7-5 HOW TO CHECK THE VIBRATION SENSOR
