Your Guide to LG Dryer Error Codes and Quick Fixes

Use the full model number when interpreting an LG dryer display. LG’s current U.S. dryer guide lists dryer-specific codes and notes that procedures can differ by model. The code list below follows that guide; do not apply washer-only meanings to a dryer.

See LG’s official U.S. dryer error-code list and the manual for your exact model for the complete procedure.

LG dryer codes in the current support guide

• d80, d90, d95: Flow Sense indicators for restricted airflow between the dryer and the outside exhaust. Follow LG’s model-specific vent and lint checks; arrange professional vent cleaning or dryer service when needed.
• tE1, tE2, tE3, tE4, tE5, tE6: Thermistor-related fault family. LG lists a power reset as an initial step; if a code returns, request service rather than testing or replacing internal sensors.
• dE / dE4: The dryer door is not completely closed. Check for clothing caught in the door or a filter that is not seated as the manual directs.
• E13: Listed for LG Hybrid Condensing Dryers only. It indicates a kinked, crushed, or clogged drain hose, or water frozen in the sump. Follow the exact model instructions.
• FO / “INSERT FILTER”: Check that the lint filter is inserted correctly.
• HS: Humidity-sensor indication. LG’s guide describes cleaning the accessible sensors below the lint filter and requesting service if the code persists.
• PS: Improper voltage at the power cord. Do not inspect the terminal block or wiring yourself; have installation checked by a qualified professional.
• PF: Power failure, often after an outage. Use only the model’s documented reset steps.
• gAS: The dryer is not receiving gas. Stop troubleshooting and arrange qualified service if the supply appears unavailable or the message remains.
• CL: Child Lock. The button and hold sequence vary by model; use the owner’s manual.
• E05: A steam-cycle water-supply issue on applicable models. Consult the model manual for the correct checks.

Codes not covered by your model’s guide

Do not treat LE, HE, or UE as universal LG dryer codes. They are not listed as general dryer codes in LG’s current U.S. support guide; a code meaning may depend on the exact product and model. Check the matching manual or contact LG support before diagnosing it. Avoid opening the cabinet, testing wiring, or replacing internal parts based on a generic code list.

If a code persists after the model manual’s basic checks, arrange qualified dryer service. Smart Appliance Services can help with a persistent LG dryer issue.
