If your LG washing machine CE error code has appeared on the display, it indicates a critical electrical issue that requires immediate attention. This code, officially defined as a “Current Error,” signifies that the washer’s internal monitoring system has detected an abnormally high electrical current flowing through the motor circuit.
Unlike minor operational glitches, the CE error is a safety mechanism designed to protect the machine from severe electrical damage. It usually halts the cycle immediately to prevent overheating or fire hazards. While this can be alarming, understanding the underlying causes—ranging from a simple power surge to a complex short circuit—is the first step toward a solution.
Understanding the CE Error Code
The CE error typically occurs on an Inverter Direct Drive system, which is standard in most modern front load washer models from LG. In these machines, the motor is directly attached to the drum without belts or pulleys.
When the Main control board detects that the motor is drawing more current than the safe limit allows, it triggers the CE code. This “over-current” state is often the result of the system trying to overcome a mechanical resistance or an electrical short, leading to a safety shutdown.
Common Causes of the CE Error
Several factors can trigger this specific error code. Identifying the root cause is essential before attempting any part replacements.
- Power Surge: A sudden spike in your home’s voltage can overload the washer’s sensitive electronics.
- Short Circuit: Damaged internal wiring or a fault within the electronic components can create a direct path for electricity to flow where it shouldn’t.
- Motor Stator Issues: The Stator assembly, which consists of copper coils that create the magnetic field to spin the rotor, may have a shorted winding.
- Main Control Board Failure: The “brain” of the washer may be reading signals incorrectly or may have a blown component (like a triac) that regulates power to the motor.
- Commutation Error: If the timing of the electrical pulses sent to the motor is off, the motor may struggle to turn, causing a spike in amperage.
How to Fix the LG Washing Machine CE Error
Diagnosing this issue requires a systematic approach. Follow these steps to isolate the problem, starting with the simplest solutions.

1. Perform a Hard Reset
Before disassembling the machine, rule out temporary electronic glitches caused by a Power surge.
- Unplug the washing machine from the power outlet.
- Press and hold the “Start/Pause” button for 5 seconds to dissipate any residual static electricity.
- Leave the machine unplugged for at least 3 minutes.
- Plug it back in and attempt to run a Rinse + Spin cycle.
If the error clears, it was likely a transient spike. If the code returns immediately or during drum rotation, proceed to the next steps.
2. Inspect the Wiring Harness
A damaged Wiring harness is a frequent culprit. Constant vibration during the spin cycle can cause wires to rub against the metal chassis, wearing down the insulation and causing a Short circuit.
- Disconnect power to the washer.
- Remove the top or back panel (depending on your model) to access the internals.
- Visually inspect the wire bundles connecting the Main control board to the motor. Look for blackened wires, melted insulation, or exposed copper.
- Check the ground wire connections to ensure they are tight and corrosion-free.
3. Check the Motor Stator and Rotor
The Motor stator is a stationary part of the Inverter Direct Drive system. If the coils on the stator are damaged, they will draw excessive current.

- Access the Motor: Remove the back panel of the washer. You will see the large circular rotor.
- Inspect for Physical Damage: Look for cracks in the magnets on the rotor or burnt spots on the stator coils.
- Test the Stator: You will need a multimeter. Disconnect the wire connector from the stator. Measure the resistance (Ohms) between the three terminals (usually 1-2, 2-3, and 1-3). The reading should be consistent across all pairs (typically between 5 to 15 Ohms, depending on the model). A reading of “Zero” or “Infinity” on any pair indicates a bad Stator assembly.
4. Examine the Hall Sensor
The Hall sensor (also known as the Rotor Position Sensor) monitors the position of the rotor to ensure smooth rotation. While a faulty Hall sensor typically triggers an “LE” (Lock Error) code, it can occasionally contribute to a CE error by causing a Commutation error.
- If the sensor provides incorrect position data, the control board may energize the wrong stator coils at the wrong time. This misfire forces the motor to fight against itself, resulting in a massive current spike.
- Inspect the Hall sensor clipped onto the stator for moisture or corrosion. If you are replacing the stator, it is best practice to replace the Hall sensor simultaneously.
5. Verify the Main Control Board
If the motor, wiring, and sensors all test fine, the issue likely lies with the Main control board.
- The board contains power inverters that drive the motor. If these components fail (often due to a previous short circuit), they may continuously deliver high current or fail to regulate voltage properly.
- Look for visible burn marks or swollen capacitors on the board, which is usually located behind the front control panel or in the rear top corner.
- If the board is faulty, it must be replaced to resolve the CE error.
Summary
The LG washing machine CE error is a protective measure against high electrical current. While a Hard reset fixes minor glitches, persistent errors usually point to a failure in the electrical path between the Main control board and the Inverter Direct Drive motor. By carefully inspecting the Wiring harness, Motor stator, and Hall sensor, you can identify the source of the short circuit and restore your washer to working order. Always prioritize safety and disconnect power before testing internal components.
Frequently Asked Questions
What does the CE error code on an LG washing machine mean?
The CE error stands for “Current Error.” It is a safety mechanism that indicates the washer’s internal monitoring system has detected an abnormally high electrical current flowing through the motor circuit. The machine typically halts the cycle immediately to prevent overheating or potential fire hazards.
How do I perform a hard reset to try and clear the code?
To perform a hard reset, unplug the washing machine from the power outlet. Press and hold the “Start/Pause” button for 5 seconds to dissipate residual electricity, then leave the machine unplugged for at least 3 minutes. Plug it back in and attempt to run a Rinse + Spin cycle to see if the error persists.
Can a power surge cause a CE error?
Yes, a sudden spike in your home’s voltage can overload the washer’s sensitive electronics and trigger the CE code. If the error was caused by a transient power surge, a hard reset will usually clear the code and allow the machine to function normally again.
What hardware components are usually responsible for a persistent CE error?
If a reset does not work, the problem is often found in the wiring harness (due to a short circuit), the motor stator (shorted coils), or the main control board (failed power inverters). A faulty Hall sensor can also contribute to the error by causing a commutation error that forces the motor to draw excessive amperage.
Is it safe to continue using the washer if the CE error appears intermittently?
No, it is not recommended to ignore this error. Because the CE code signifies an over-current state, continuing to use the machine could lead to severe electrical damage, melted wiring, or a fire hazard. The underlying electrical issue should be diagnosed and repaired before the machine is put back into regular service.
