The EE error code on an LG washer indicates a fault in the EEPROM — the small memory chip on the main control board that stores the machine's configuration data, calibration settings, and cycle programming. When this memory cannot be read or written correctly, the washer halts and displays EE. Start with a hard reset — a power-cycle sometimes clears a transient memory read error. If EE returns persistently, the control board itself needs to be replaced by a technician, as the EEPROM chip is not a user-serviceable component.
What the EE Code Means
The LG washer EE error code points to an EEPROM fault. EEPROM stands for Electrically Erasable Programmable Read-Only Memory — it is a tiny non-volatile memory chip soldered onto the main control board (PCB). This chip holds the machine's essential operating data: factory calibration values, user settings, cycle programming, motor parameters, and regional configuration. Every time the washer runs, it reads and writes to this chip.
When the control board's processor attempts to read from or write to the EEPROM and receives an error — either because the chip has degraded, suffered a write fault from a power surge, or developed a hardware failure — the board cannot trust its own configuration data and displays EE to alert the user that a fundamental memory integrity problem exists.
Unlike most other LG washer error codes, EE is not caused by a mechanical or plumbing issue. It is exclusively an electronics fault. The physical drum, motor, pump, and hoses are not the problem. The issue lives entirely within the control board's memory circuit. This means DIY mechanical fixes will not resolve it — the only paths forward are a successful hard reset (which works in a minority of cases) or control board replacement.
EE can appear suddenly after a power outage, a voltage spike, or simply through normal wear of the EEPROM chip over years of use. It is more commonly seen on older machines that have accumulated many write cycles to the memory chip.
Common Causes — Most Likely First
How to Fix the EE Error — Step by Step
Perform a hard reset — unplug for 5 minutes
Unplug the washer from the wall outlet completely. Wait a full 5 minutes — not just a few seconds. This extended power-off period allows all capacitors on the control board to discharge fully, which gives the EEPROM the best chance of reinitializing cleanly on the next power-up. Plug back in and attempt to start a cycle.
Check your home's power supply
Before concluding the board is faulty, verify that the wall outlet the washer is plugged into is delivering stable voltage. Plug another appliance into the same outlet to confirm it is working normally. If the washer is plugged into an extension cord or a power strip, move it to a direct wall outlet — control boards are sensitive to voltage drop through extension cords and this can cause erratic behavior including memory faults.
Run a test cycle after the reset
After plugging back in, run a simple short cycle — a Rinse + Spin or Quick Wash. If the cycle completes without EE reappearing, the fault was a transient memory error cleared by the hard reset. Run two or three more complete cycles over the next few days to confirm the code does not return before considering the issue resolved.
If EE returns — attempt a second extended reset
If EE reappears after the first reset, unplug the washer again and leave it unpowered for 30 minutes this time. This longer period ensures complete discharge of any backup capacitance on the board. Plug back in and test again. Some boards recover after a longer discharge window following a power surge event.
Inspect the control board for visible damage (advanced)
If you are comfortable with basic electronics inspection, unplug the machine, access the control board by removing the top or rear panel (varies by model), and visually inspect the board for burn marks, swollen capacitors, corrosion on the board traces, or signs of water damage near the EEPROM chip. The EEPROM is typically a small rectangular IC chip on the PCB. Any visible damage confirms the board needs replacing.
Replace the main control board
If EE persists through all reset attempts and no other cause is found, the main control board requires replacement. This involves sourcing the correct LG PCB for your specific model number, disconnecting all wiring harness connectors from the existing board, mounting the new board, and reconnecting all connectors in the correct positions. Incorrect connector placement can cause additional faults or permanent damage to the new board.
Consider the machine's age before investing in a board replacement
Control board replacement is the most expensive single repair on a washer. If the machine is more than 10 years old and the board cost approaches or exceeds 50% of a replacement washer's value, it is worth comparing repair cost versus replacement before committing. A Promix technician can give you an honest assessment of whether repair makes financial sense for your specific model and situation.
When to Call a Technician
EE is one of the few LG washer errors that almost always requires professional service. Book a certified LG technician if:
- EE returns after a full 5-minute hard reset — repeated resets will not fix a corrupted or failed EEPROM
- EE appears immediately on every power-up before any cycle is attempted
- You see EE alongside other unrelated error codes appearing in the same session — this suggests broad board failure rather than a single fault
- You find burn marks, corrosion, or swollen capacitors on the control board during inspection
- The machine is less than 5 years old and EE appeared after a power outage — this may be a warranty-eligible event

Frequently Asked Questions
What does EE mean on an LG washer?
EE stands for an EEPROM memory fault. The EEPROM is a small memory chip on the main control board that stores the washer's configuration data, calibration settings, and cycle programming. When the control board's processor cannot read from or write to this chip correctly — due to chip degradation, a power surge, or broader board failure — it displays EE and halts the machine. Unlike most washer errors, EE has nothing to do with water, draining, spinning, or heating — it is purely an electronics fault.
Can a power outage cause the EE error on an LG washer?
Yes — this is one of the most common triggers. If power is cut abruptly while the control board is in the middle of a write operation to the EEPROM, the write can be left incomplete and corrupt the stored data. A voltage spike when power is restored can also damage the chip directly. If your EE error appeared immediately after a power outage or storm, try a full 5-minute hard reset first. If the code persists, the board likely needs replacement.
Will resetting my LG washer fix the EE error?
Occasionally yes, usually no. A hard reset — unplugging for a full 5 minutes to allow the board to discharge completely — can clear a transient EE caused by a one-time read error. However, if the EEPROM chip has genuine data corruption or hardware damage, no amount of resetting will fix it. The only resolution in that case is control board replacement. If EE returns after one or two reset attempts, stop resetting and book a professional repair.
Is the EE error dangerous — can I keep using the washer?
The EE fault itself does not create an immediate safety hazard, but you should not continue using the machine with a persistent EE code. The washer's control board cannot reliably read its own operating parameters, which means cycle behavior is unpredictable. In practice, most machines displaying EE will refuse to start or will stop mid-cycle, so continued use is usually not possible anyway. Do not attempt to bypass the error.
How much does it cost to fix an LG washer EE error?
If a hard reset clears it, the repair costs nothing. If the control board needs replacing, expect $220–$420 in the Boston area, depending on your specific LG model and the cost of the board. Some older or discontinued models have scarce parts that push the cost higher. It is worth getting a professional diagnosis first to confirm the board is the issue and to get an accurate parts quote before committing to the repair.
Is the EE error covered under LG's warranty?
LG's standard one-year limited warranty covers defects in materials and workmanship. An EEPROM or control board failure within the warranty period due to a manufacturing defect should be covered. Damage caused by a power surge or outage is typically considered an external event and may not be covered under the standard warranty — though some homeowner's insurance policies cover appliance damage from power events. Contact LG directly with your model number, serial number, and purchase date to confirm your coverage before booking third-party service.
