LG washer FE / E04 / E12: overfill condition
LG identifies FE/E04/E12 as an overfill condition. Because overfilling can create water damage, the path prioritizes stopping incoming water and service if the condition returns.
What this guide covers
Error codes: FE, E04, E12
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Safe troubleshooting sequence
Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.
- Is the washer still filling or at risk of overflowing?An active overfill should be controlled before any reset attempt.

Recurring overfill can involve water-level sensing, inlet control, drainage, or related internal systems.

When professional diagnosis is the safer next step
An active overfill is not a condition to keep testing. Recurring overfill can involve water-level sensing, inlet control, drainage, or related internal systems.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
