HE points to the washer’s heating function. Since that system combines water, temperature sensing, mains electricity, and internal components, external observation is useful while live or disassembled testing is not.
LG washer HE code: LG’s washer error list identifies HE as a heater error. The public guidance allows powering the appliance down and restoring power once, but a persistent code needs professional diagnosis.
The direct answer
Recognize an LG heater error and avoid unsafe internal tests.
Work through these checks
- Stop the cycle and let the washer cool and unlock normally.
- Switch it off and unplug it from a dry, safely accessible outlet.
- Note the selected temperature, cycle stage, and whether the door or laundry seemed abnormally hot.
- After a short rest, restore power and try one model-supported cycle.
- If HE returns, discontinue use and arrange LG service.
Possible reasons
- A temporary heater-control error.
- A heater, temperature-sensing, connection, wiring, or electronic control condition.
- A model-specific operating condition that prevents normal heating feedback.
How to interpret what you see
Cool-feeling laundry does not prove a failed heater; cycles use different target temperatures and heating stages.
Do not measure live voltage, bridge a thermal device, or open the cabinet for a code-only test.
A power cycle can clear a temporary state but cannot repair a recurring heating circuit fault.
One successful retry is useful evidence, but it is not proof that a damaged component repaired itself. Write down the cycle and stage if the message returns. A repeatable pattern gives support or a technician more useful information than repeated restarts, and it reduces the chance of turning a manageable fault into water or electrical damage.
Check the exact model before going further
HE usage can differ among LG washer, combo, and WashTower platforms. Confirm the code in the exact model’s support literature.
When the washer needs service
Leave the washer disconnected and seek service if HE repeats, the appliance becomes unusually hot, an electrical smell appears, or a breaker trips.
Document the circumstances without disassembling the washer: exact display, model, cycle, load, water level, unusual sound or smell, and whether the warning returned after the approved check.

Frequently asked questions
Can I wash on cold after HE?
Do not use another cycle to bypass a recurring heater error; obtain model-specific support.
Does unplugging fix HE?
It may clear a temporary state once, but it does not repair a recurring heater or sensing fault.
