CE2
LG Washing Machine
Severity: CriticalWhat Does This Error Mean?
The CE2 error means the washer has detected abnormal electrical current — a potential current leakage. This is a safety shutdown to protect you from electric shock. Do not ignore this error — it requires prompt attention.
Affected Models
- WM3900HWA
- WM4000HWA
- WM3500CW
- WM3700HWA
- Most LG front-load washers
Common Causes
- Water has entered the washer's electrical components — usually from a leak
- Wiring insulation has worn through and is allowing current to escape
- Heating element is partially failing and creating electrical leakage
- The outlet or circuit is not properly grounded
- Internal component (motor, pump, control board) has developed an electrical fault
How to Fix It
-
Unplug the washer from the wall immediately.
Do not reach into the drum with the washer plugged in while this error is active.
-
Check that the outlet the washer is plugged into is properly grounded.
A three-prong outlet is required. Use an outlet tester (available at hardware stores for under $10).
-
Inspect the area under and around the washer for any signs of water leakage.
Water near electrical components is the most common cause of CE2.
-
Do not plug the washer back in until a technician has inspected it.
This error should not be dismissed as a glitch — it is a safety warning.
-
Contact LG support (1-800-243-0000) or a certified appliance technician to diagnose the fault.
Depending on the cause, repairs range from fixing a leak to replacing a heating element or control board.
When to Call a Professional
The CE2 error is a safety-critical fault — do not attempt to diagnose or repair electrical leakage yourself. Unplug the washer immediately and do not use it until a certified technician has inspected it. Electrical leakage in a water-filled appliance is a shock hazard.
Frequently Asked Questions
Is CE2 dangerous?
Yes — it means electrical current is leaking somewhere it should not be. In a wet environment like a washer, this is a shock hazard. Unplug the machine and keep it unplugged until it is professionally inspected.
Can a CE2 error be caused by a bad outlet?
Yes — an ungrounded or faulty outlet can contribute to the error. But even if the outlet checks out, the fault may be inside the washer itself. Both need to be verified by a qualified person.
How much does it cost to fix a CE2 error on an LG washer?
It depends entirely on the cause. A simple grounding issue is free to fix. A leaking hose causing water damage to electronics can cost $100–$300. A failed heating element or control board can run $200–$400.
