LG Washing Machine Error Code EE — What It Means & How to Fix It

What Does This Error Mean?

The EE error means the EEPROM memory chip on your LG washer's control board has failed. The EEPROM stores the washer's programming and settings. When this chip cannot be read or written to, the washer cannot operate at all.

Affected Models

LG WM3900HWA
LG WM4000HWA
LG WT7300CW
LG WM2250CW
LG WM8100HVA

Common Causes

The EEPROM chip on the main control board has been corrupted by a power surge
The main control board has a hardware defect that developed over time
A power outage or sudden loss of electricity corrupted the stored data on the chip
The control board's wiring connections have come loose from vibration during operation
Moisture or condensation reached the control board and damaged the electronic components

How to Fix It

Unplug the washer from the wall outlet. Wait at least 10 minutes to allow the control board to fully discharge.

Sometimes a complete power drain allows the EEPROM to reset on the next startup.
Plug the washer back in and try to start a cycle. If the EE error clears, the issue was a temporary glitch caused by a power disturbance.

If the error returns immediately, the EEPROM chip is likely permanently corrupted.
Make sure the washer is plugged into a properly grounded outlet. Check that the outlet has stable voltage with no flickering lights nearby.

Unstable power is a leading cause of EEPROM corruption. Consider adding a surge protector.
Check the wiring connections to the main control board if you are comfortable removing the washer's top panel. Look for loose or corroded connectors.

The control board is usually located at the top-back of the washer behind a metal cover. Always unplug first.
If the error persists, contact LG support at 1-800-243-0000 or schedule a service visit. The control board will likely need to be replaced or reprogrammed.

Have your washer's model and serial number ready. They are printed on a label inside the door frame.

When to Call a Professional

The EE error almost always requires a professional technician. The main control board may need to be reprogrammed or replaced entirely. A new control board costs $150 to $350 depending on the model. Professional diagnosis and installation adds $100 to $200 in labor. Do not attempt to repair the control board yourself unless you have electronics experience.

Frequently Asked Questions

What is an EEPROM and why does it matter?

EEPROM is a small memory chip on the washer's main control board. It stores the washer's programs, cycle settings, and calibration data. Think of it like the washer's brain — without it, the machine does not know how to run any cycles.

Can a power surge cause the EE error?

Yes. Power surges are one of the most common causes of EEPROM corruption. A lightning strike, power outage, or voltage spike can damage the chip. Using a surge protector on the outlet can help prevent this in the future.

Is it worth repairing or should I replace the washer?

If the washer is less than 5 years old, repairing the control board is usually worth it. The repair costs $250 to $500 total, which is much less than a new LG washer. If the washer is older than 8 years, replacing it may be more cost-effective.
