What Your Machine Is Actually Telling You
CE means the inverter board detected that the motor current exceeded its safe operating limit. LG's overcurrent protection triggered to prevent motor and board damage.
Why overcurrent happens: The Direct Drive motor draws more current when under heavy mechanical load. If the drum is overloaded, bearings are failing, or the motor itself has a winding fault, current spikes.
Common causes:
1. Overloaded drum (30%) — too much weight.
2. Motor winding fault (20%) — partial short in stator coils.
3. Inverter board (15%) — IGBT transistor failing.
4. Worn bearings (15%) — increased friction = more current.
5. Object between tubs (10%) — mechanical resistance.
6. Wiring issue (10%) — damaged motor harness.

What You're Probably Seeing Right Now
- CE during spin — highest current draw.
- Machine was running a very heavy load.
- CE on every load — motor or board issue.
- Burning smell from back of machine.
- Motor hums loudly before CE appears.
DIY Fix — From Easiest to Hardest
1
Reduce Load (1 minute — Fixes 30%)
1. Remove half the laundry.
2. Redistribute.
3. Restart.
**Max capacity:** Fill drum 3/4 full.

Power Reset (5 minutes)
1. Unplug for 10 minutes.
2. This clears overcurrent protection.
3. Try with small load.

Check for Mechanical Resistance (5 minutes)
1. Empty drum completely.
2. Spin by hand.
3. **Smooth** = motor/board issue.
4. **Grinding** = bearings.
5. **Clicking** = foreign object.

4
Test Motor Stator (10 minutes)
1. Remove back panel.
2. Disconnect stator connector.
3. Measure coil resistance: **5-10Ω** each phase.
4. Very low = shorted winding.
5. Ground test: coil to frame = must be OL.

Inspect Inverter Board (5 minutes)
1. Look for burned components.
2. Swollen capacitors.
3. Discolored IGBT modules.
4. Replace board if damaged ($80-200).

When to Call a Pro
- •Stator replacement — $100-$280 installed.
- •Inverter board — $120-$350.
- •Bearing replacement — $250-$500.
- •Burning smell = stop using immediately.
