4-2. CORRECTIVE ACTIONS FOR EACH ERROR CODE
These are common troubleshooting procedures for each drum-type washer error mode. For detailed information, refer to the general repair scripts.
Error Type Error Mode Causes Corrective Actions Description of Photo
Water Level
Sensor
1E
• Water level sensor fault
• Incorrect connections of the water
level sensor terminal
• The hose part for the water level
sensor is folded.
• Main PCB fault
• Check the water level sensor terminal
connections and contacts.
• An error occurs if an incorrect water level
sensor is used. Make sure to check the
material code. (Abnormal operation)
• If the water level sensor is faulty, replace it.
• If the error persists despite taking the action
above, replace the PBA.
Check the water level sensor
frequency.
- Check it after the water level
sensor and the connector
are connected.
- Frequency: Approx. 26.1
KHz with no load
Washing Motor
Error and Hall
Sensor Error
3E
3E1
3E2
3E3
3E4
• 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.
• 3E1 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 disconnections due to foreign
material.
• If the PBA control circuit is faulty, replace the
PBA.
MAIN PCB
Check the resistance on the
main PCB motor.(Between pins
1 and 3, and 1 and 2 of the
three(3) pins)
- Resistance : Approx. 2 to
5M
- Check the voltage when the
power is on.
[Motor Power] [Hall Sensor ]
Inverter BLDC Motor
Check the resistance on the
Motor Power & Hall Sensor

Any Terminal 2pin Check
4.8~4.95
- Hall Sensor
