The digits indicate the water level frequency.
So, for example a display indicating 255 :
a water level frequency of (255 X 0.1) = 25.5KHz

Reference of checking the vibration
sensor error
sensor error
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.
