Motor Error Troubleshooting Steps
- Power Reset: Unplug the washing machine for 10 minutes, then restart
- Check Load: Ensure load is balanced and not exceeding capacity
- Inspect Drum: Check for foreign objects obstructing drum movement
- Professional Service: If error persists, contact authorized LG service center
Direct Drive Motor Protection
LG's Direct Drive motor includes multiple protection systems that automatically trigger error codes to prevent damage to the motor and other components.
Water System Error Codes
IE1 - No Water Flow
Water not entering the machine. Check water supply valves, hoses, and inlet filters for blockages.
IE2 - Slow Water Fill
Water entering too slowly. Low water pressure or partially clogged filters. Clean inlet filters and check water pressure.
IE3 - Overfill Protection
Water level too high. Pressure switch or water valve malfunction. May require professional service.
IE4 - Water Temperature Error
Heating system malfunction. Check temperature sensors and heating elements.
IE5 - Water Valve Error
Water inlet valve failure. Valve not opening/closing properly. Replacement may be necessary.
IE6 - Water Level Sensor
Pressure sensor malfunction. Incorrect water level detection. Professional diagnosis required.
Water Error Quick Fixes
- Ensure both hot and cold water valves are fully open
- Check water hoses for kinks or damage
- Clean water inlet filters monthly
- Verify adequate water pressure (20-116 psi)
- Use recommended detergents only
Drain System Error Codes
| Error Code | Specific Issue | Immediate Action |
|---|---|---|
| OE1 | Drain Timeout - Water not draining within expected time | Check drain hose for obstructions, ensure proper installation height |
| OE2 | Drain Pump Error - Pump not operating correctly | Clean drain pump filter, check for foreign objects in pump |
| OE3 | Drain Sensor Error - Water level detection issue during drain | Reset machine, check pressure sensor connections |
| OE4 | Drain Blockage - Severe obstruction in drainage system | Emergency drain procedure, clean all drainage paths |
| OE5 | Drain Motor Error - Pump motor malfunction | Professional service required for motor replacement |
| OE6 | Drain Communication Error - PCB communication failure | Power reset, if persists main control board may need service |
Drain System Maintenance
Monthly Maintenance Steps:
- Clean drain pump filter (refer to user manual for location)
- Inspect drain hose for kinks or damage
- Ensure drain hose height is 60-100 cm from floor
- Run cleaning cycle with washing machine cleaner
- Check drain hose connection to standpipe
Sensor Error Codes
| SE1 | Temperature Sensor Error - Inaccurate water temperature reading |
| SE2 | Pressure Sensor Error - Water level detection malfunction |
| SE3 | Vibration Sensor Error - Unbalance detection system failure |
| SE4 | Door Sensor Error - Door status detection issue |
| SE5 | Motor Sensor Error - RPM and position sensing failure |
| SE6 | Communication Error - Sensor to main board communication loss |
