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’.
