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.
