LG Dryer Error Codes List: Every Code Explained
Every LG dryer error code we could verify against LG's own documentation — what it means, what usually causes it, and the first fix to try — in one table. Codes differ between model series, so treat your model's tech sheet as the final word.
How to read and retrieve error codes on LG dryers
LG dryers have an installation/test mode (used at install to verify venting and, on gas models, the gas connection) and a service test mode that steps through motor, heater, steam and sensor checks while showing stored codes (the tE family and others). The entry sequence is model-specific and printed in the service manual; running the install test after any vent work is the fastest way to confirm a Flow Sense fix.
The complete LG dryer error code list
| Code | Meaning | Most likely cause | First fix |
|---|---|---|---|
| ADD | Add water notice; the steam feeder needs water for a steam cycle. | Steam feeder empty or drawer not completely closed. | Fill the steam feeder with tap water to the max line; close the drawer. |
| AE | Compressor error on heat-pump WashTower dryers; shown with LE2 (fold 'AE'). | Fault in the compressor that generates heat for drying. | Unplug, wait one minute, reconnect and retry; request service if it persists. |
| CL | Child Lock is ON — not an error (panel locked). | Child Lock activated | Hold the Child Lock button (or the marked pair) ~3 seconds until CL clears — the pairing is printed on the panel. |
| D80 | Flow Sense: exhaust airflow is about 80% blocked — vent restriction warning (80% level of the D80/D90/D95 family). | Lint build-up in the vent run | Clean the entire vent run properly (rotary brush kit or a vent-cleaning service) — from the dryer to the outside hood, not just the ends. |
| D90 | Flow Sense: exhaust about 90% blocked — serious vent restriction (mid-level of the D80/D90/D95 family). | Advanced lint blockage in the vent run | Full vent-run cleaning (brush kit or service), hood to dryer. |
| D95 | Flow Sense: exhaust about 95% blocked — the dryer stops for safety (top of the D80/D90/D95 family). | Completely lint-blocked vent run | Clean the full vent run with a rotary brush; clear/repair the hood; replace crushed or foil hose with metal duct. |
| E13 | Drain error on hybrid condensing dryers; sump water cannot drain. | Drain hose kinked, crushed or clogged, or water in the sump frozen. | Straighten and clear the drain hose, use only the standard hose, restart. |
| FO | Filter notice (display F0); the lint filter is out of its housing. | Lint filter removed or not seated in the filter housing. | Remove the lint filter and reinsert it fully into the filter housing. |
| H5 | Humidity sensor error — the dryer's moisture (humidity) sensor is faulty or its signal is implausible. | Sensor strip contamination | Clean the strips (above) — always the first step. |
| HS | Humidity sensor error; the humidity sensor is faulty. | Dirty or faulty humidity sensor below the lint filter. | Wipe the sensors with a damp rag, let them dry fully, then retry. |
| IF | Filter installation notice on WashTower dryers; the lint filter is not detected (fold 'IF'). | Lint filter incorrectly assembled, or its interior-filter magnet missing or misplaced. | Assemble both filter parts correctly and check the magnet is in place. |
| LE1 | Motor error variant on LG dryers — LE-family motor fault (locked/abnormal motor operation) as rendered on certain dryer platforms. | Broken belt or jammed drum | Open the cabinet (unplug) and service belt/idler/rollers; clear obstructions. |
| LE2 | Compressor error on heat-pump WashTower dryers; problem with the drying compressor (fold 'LE2'). | Fault in the compressor that generates heat for drying. | Unplug, wait one minute, reconnect and retry; request service if it persists. |
| LE3 | Air circulation motor error on WashTower dryers. | Problem with the motor that circulates air in the dryer. | Unplug, wait one minute, reconnect and retry; request service if it persists. |
| NP | No Power / power-supply issue — the dryer (typically a gas model or electric model) reports an electrical power problem at the control. | Supply problem at the outlet | Restore a verified supply (electrician for outlet/terminal faults — dryer circuits are high-current). |
| OE | Drain error on WashTower dryers (also shown as drn); water is not draining (fold 'OE'). | Drain hose pressed, installed too high, clogged, or frozen. | Straighten and unclog the drain hose; thaw with warm water if frozen. |
| PF | Power failure code; often appears after a power outage. | Power outage or interrupted supply during a cycle. | Unplug, hold Start/Pause five seconds while unpowered, restore power and run a cycle. |
| PS | Power error; improper voltage within the power cord. | White and red wires reversed on the dryer's terminal block. | Check the power cord connection at the terminal block; have the installer correct it. |
| TE1 | Thermistor error (sensor 1) — the exhaust/outlet thermistor is faulty. | Thermistor failure | Clear lint from the sensor and housing. |
| d75 | Flow Sense warning; the exhaust duct is clogged about 75 percent. | Lint buildup, or a crushed or damaged exhaust duct. | Clean lint from the exhaust duct system; repair any crushed duct sections. |
| dE | Door error; the dryer door is not completely closed (fold 'DE'). | Door open, lint filter not pushed in, or clothing stuck on the door. | Seat the lint filter fully, clear the door, close it firmly and restart. |
| tE2 | Thermistor error, normally during cold conditions or steam cycles (fold 'TE2'). | Duct cools too fast from steam-cycle humidity in cold conditions. | For steam cycles, select Steam Fresh, set load to big, and start. |
| tE3 | Thermistor error; a problem was detected with the dryer's thermistor. | Faulty thermistor (temperature sensor). | Reset the dryer as for PF; request service if the code persists. |
How to reset / clear error codes on LG dryers
LG dryer codes clear with a power cycle: unplug for about 5 minutes, hold the Power button for a few seconds while unplugged on some models, restore power and run a test load. Flow Sense bars and codes like D80 are computed fresh from airflow measurements each cycle, so they only 'reset' by fixing the airflow — a power cycle alone cannot clear a genuine restriction.
How to diagnose any LG dryer code
Work the problem in this order: (1) record the code exactly, including whether it appears at start-up or mid-cycle — a code at start-up usually reports a failed self-check (sensor, door, motor circuit), while a mid-cycle code reports a process that drifted (airflow, temperature, load sensing); (2) for airflow codes, inspect the whole vent path before anything else: lint screen (wash it — dryer-sheet film blocks air invisibly), transition duct, wall cap and the full run for crushed or lint-packed sections; (3) for heat codes, confirm the drum turns and air moves — heat without airflow and airflow without heat are different fault trees; (4) clear the code and run a timed dry with a small load of wet towels while you monitor: does it heat, does the exhaust blow strong outside, does the code return at the same point; (5) test the monitored component (thermistor, moisture sensor, motor circuit) only after the path and the load are proven good. On gas dryers, anything past the external vent path is a technician's job.
The Flow Sense airflow codes on LG dryers
Three LG dryer codes do not report a broken part at all — they report how much of the exhaust airflow is blocked, measured by the Flow Sense system. They are the most common LG dryer codes of all, and their "fix" is the vent path, not a component:
| Code | Meaning | First fix |
|---|---|---|
| D80 | Flow Sense: exhaust airflow is about 80% blocked — vent restriction warning (80% level of the D80/D90/D95 family). | Clean the entire vent run properly (rotary brush kit or a vent-cleaning service) — from the dryer to the outside hood, not just the ends. |
| D90 | Flow Sense: exhaust about 90% blocked — serious vent restriction (mid-level of the D80/D90/D95 family). | Full vent-run cleaning (brush kit or service), hood to dryer. |
| D95 | Flow Sense: exhaust about 95% blocked — the dryer stops for safety (top of the D80/D90/D95 family). | Clean the full vent run with a rotary brush; clear/repair the hood; replace crushed or foil hose with metal duct. |
If D90 returns soon after a clean: Fast recurrence after a proper clean means lint is bypassing the filter (torn filter/housing gap) or the run itself is unsuitable (too long/too many elbows) and needs re-routing.
If D95 returns soon after a clean: D95 recurring quickly after cleaning means the run is fundamentally inadequate (too long, too many elbows, sagging flex) — re-route or shorten it, or lint will win every time.
Deep dive: What Flow Sense means · D80 error code guide.
The most searched LG dryer codes, in detail
CL — Child Lock is ON
CL on an LG dryer means Child Lock is active: buttons are disabled so settings can't be changed mid-cycle by small hands. It is a status, not a fault — and on LG laundry it is confused with LE constantly (on dryers there is no LE motor code in the washer's sense, which doubles the confusion).
Most likely cause: Child Lock activated — Deliberately, or by a long press on the marked button pair.
First check: Look for the lock icon; test a button — beep without response confirms the lock.
If it keeps coming back: Self-re-engaging CL suggests a sticking panel button.
D80 — Flow Sense: exhaust airflow is about 80% blocked
LG's Flow Sense system measures the dryer's exhaust restriction. D80 means roughly 80% blocked: the dryer still runs, but drying times stretch, energy use climbs, and lint-heat builds where it shouldn't. D80 is the early warning of the family — D90 and D95 are its louder siblings, and D95 stops the dryer. All three are vent-system codes, not dryer-part codes: the house vent run is the patient.
Most likely cause: Lint build-up in the vent run — The leading cause — especially long runs, runs with many elbows, and foil-flex hose that traps lint in its ridges.
First check: Water test the lint filter: run water through it — if water pools instead of passing, softener film is choking it (scrub with hot soapy water and a brush).
If it keeps coming back: If D80 returns within weeks of a thorough vent clean, lint is accumulating abnormally fast — check for a torn lint filter letting lint bypass into the duct, and confirm the exterior hood isn't re-blocking (nests/snow are seasonal repeat offenders).
D90 — Flow Sense: exhaust about 90% blocked
D90 means LG's Flow Sense measures the exhaust at roughly 90% restricted. Drying will be noticeably poor by now — long cycles, clothes still damp — and heat that should leave with the exhaust is staying in the dryer. This is the 'clean the vent this week' stage: the next step in the family (D95) stops cycles, and sustained running against a near-blocked vent is a genuine lint-fire risk factor.
Most likely cause: Advanced lint blockage in the vent run — The usual cause at 90%.
First check: Outside airflow test while running — at D90 the exterior flow is a whisper.
If it keeps coming back: Fast recurrence after a proper clean means lint is bypassing the filter (torn filter/housing gap) or the run itself is unsuitable (too long/too many elbows) and needs re-routing.
D95 — Flow Sense: exhaust about 95% blocked
D95 is the Flow Sense end-state: the exhaust is effectively blocked (~95%), so the LG dryer cuts heat/cycle to protect itself and your house. Owners typically meet it as 'dryer stops mid-cycle, clothes hot and damp, D95 on the display'. The vent system — run, hose, hood, and the dryer's internal duct — is blocked somewhere, and no reset will clear D95 until air can move again.
Most likely cause: Completely lint-blocked vent run — The classic: years of build-up, often at an elbow or the hood.
First check: Do not keep restarting it — confirm airflow first: disconnect the transition hose (electric dryer; brief supervised test) and run: if D95 disappears venting into the room, the house vent is the blockage; if it persists, the restriction is inside the dryer.
If it keeps coming back: D95 recurring quickly after cleaning means the run is fundamentally inadequate (too long, too many elbows, sagging flex) — re-route or shorten it, or lint will win every time.
H5 — Humidity sensor error
H5 is one of the least-documented LG dryer codes (it belongs to the moisture-sensing system on sensor-dry models). The humidity sensor — typically metal strips inside the drum/filter area that sense the load's moisture by contact — tells the control when clothes are dry. When its circuit reads out of range, sensor cycles can't judge dryness and the code sets. Because documentation is thin, diagnose conservatively: the sensor strips, their wiring, and contamination of the strips are the practical suspects.
Most likely cause: Sensor strip contamination — Fabric-softener/dryer-sheet residue coats the moisture strips and insulates them — the classic sensor-dry complaint (under-drying) and a plausible H5 contributor.
First check: Clean the moisture sensor strips (inside the drum near the filter opening — two metal strips) with a cloth and a little rubbing alcohol or fine scouring pad to strip softener film.
If it keeps coming back: H5 returning after cleaning suggests the harness or board input; under-drying returning suggests the strips are re-coating (switch from dryer sheets to help it stay fixed).
LE1 — Motor error variant on LG dryers
LE1 belongs to the motor-fault family (Samsung and LG both use LE-style prefixes for motor issues; on LG dryers LE1 is met on specific platforms as the motor error rendering). The drum motor failed to start, stalled, or its feedback disagrees with the drive. As with every motor code, mechanics first: a jammed drum, broken belt, seized idler/rollers all present as 'motor error' before any electronics are guilty.
Most likely cause: Broken belt or jammed drum — The motor can't do its job against a jam, or spins free with no drum feedback.
First check: Turn the drum by hand: even moderate resistance is normal; a hard jam or suspiciously free spin (belt off) is the story.
If it keeps coming back: LE1 under full wet loads but not empty = drag or a weakening motor — inspect supports before replacing electronics.
Less common and model-specific codes
Search data shows owners also meet these codes on LG dryers: BE1, BE2, CE, D60, DE1, DRY, Dryer, E07, E1, E2, E4, E5, EE, EE1, EE2, EE3, F1, FE, FE1, HC, HE, IE, L18, LE, MP, ND, P5, TE, TE4, U02, U05, U5, UE. They are not part of the core code list LG publishes for most models — several are series-specific, abbreviated display readings, or codes carried over from a sister platform — so we do not publish meanings for them rather than guess. Treat them by symptom: note what the machine was doing when the code appeared (filling, draining, heating, spinning), run one full power cycle (5 minutes off), and if the code returns, match the symptom to the closest documented family in the table above and check the tech sheet stored inside your machine for the model-specific definition.
