Water Level
Sensor
1C
• Check if the water
level sensor is
defective.
• Check if the
water level
sensor terminal
is properly
connected.
• Check if the water
level sensor hose
is broken.
• This may occur
when The main
PCB is defective.
• Check the water level sensor
terminal connections.
• Check the part code of the water
level sensor, because if an incorrect
part is used, an abnormal operation
may occur. (Abnormal operation)
• If the water level sensor is defective,
replace it.
• If no problems were found for all of
the procedures above, replace the
PBA.
Check the water level sensor
frequency.
1. Check it after the water level
sensor and the connector are
connected.
Checking Part : Blue
Color Wire Oragne Color Wire
2. Frequency: Approx.26.4KHz
without water (Min 25.9KHz)
Washing
Motor Error
and Hall
Sensor Error
3C
• Washing motor
fault
• Washing motor
hall sensor fault
• Incorrect
connections
of the washing
motor/hall sensor
connector
• Washing motor
rotor and stator
fault
• Main PCB fault
• Check the motor connector terminal
connections and contacts.
• 3E is displayed because overloading
occurs due to too much laundry.
• If the hall sensor terminal is faulty,
replace the hall sensor.
• Check whether the stator of the
motor cover is damaged.
• Check for coil isconnections due to
foreign material.
• If the PBA control circuit is faulty,
replace the PBA.
Check the motor Winding Coil
• Plug out the connector and read
resistances at any two of the three
terminals on Motor : Should be 12Ω
(at 25℃)
Check the motor Hall Sensor
• Check the resistance on the main
PCB motor(Between pins 2 and 4, 3
and 4 of the four (4) pins)
- Resistance : Approx. 2 to 4 MΩ
- Check the voltage when the
power is on.
