LG Dryer Error Codes
One page per code — never a wall of codes to scroll through. Find the code on your display, open its page, and you get the manufacturer's meaning, the causes in the order LG checks them, the exact steps, and a plain line for where DIY stops and a technician starts.
One LG wrinkle worth knowing: LG publishes its dryer codes in regional lists that do not fully overlap. Its US list carries d75 and the display reminders (Check Filter, Add, CL); its UK list adds the steam and Wi-Fi codes (E05, nE, nF, tE4, gAS). Every guide below is built from both lists plus LG's dedicated Flow Sense and condenser-dryer articles, and says which list a code comes from.

Note: Code meanings and troubleshooting steps can vary by dryer model. Check your model manual.
| Code | What it means | |
|---|---|---|
| d75 Flow Sense | LG's Flow Sense indicates approximately 75% exhaust restriction — the first step on LG's Flow Sense scale. A venting warning, not a broken dryer. | Guide → |
| d80 Flow Sense | LG's Flow Sense indicates approximately 80% exhaust restriction. On gas dryers, LG says d80 can instead mean a lack of gas supplied to the unit. | Guide → |
| d90 Flow Sense | LG's Flow Sense indicates approximately 90% exhaust restriction — LG's immediate-attention level; the dryer may shut down to prevent overheating. | Guide → |
| d95 Flow Sense | LG's Flow Sense indicates approximately 95% exhaust restriction — the severe end of the Flow Sense scale. Clear the vent before running the dryer again. | Guide → |
| dE | Door error — the dryer is not completely closed: the door, the lint filter seating, or clothing stuck on the door. | Guide → |
| FO also F0 · flashing INSERT FILTER | The lint filter is out, or not inserted properly — the dryer stops until the filter is seated. | Guide → |
| Check Filter also labelled Clean Filter | A maintenance reminder — clean the lint filter before each use. It clears when you select a program or press Start/Pause. | Guide → |
| HS | Humidity sensor error — the dryer may run for two and a half hours and seem not to dry. LG's first fix is cleaning the sensors. | Guide → |
| tE1 / tE3 | A problem detected with the dryer's thermistor. LG files both codes in one entry: the factory reset, then service if it returns. | Guide → |
| tE2 | A thermistor problem that normally appears in cold conditions — steam cycles can cool the duct too fast and trigger it. | Guide → |
| tE4 | A thermistor problem with the temperature in the unit out of range. LG's UK list gives no user procedure — this one is service. | Guide → |
| nP | No current is being detected at the heater — LG says this normally indicates a problem with the home's electrical wiring. | Guide → |
| PS | Improper voltage within the power cord — the white and red wires may be reversed on the dryer's terminal block. | Guide → |
| PF | Power failure — it often happens after a power outage. LG's fix is the factory reset. | Guide → |
| gAS gas dryers only | The dryer is not receiving gas — check the supply valve is ON and the line is not kinked; anything beyond that is service. | Guide → |
| E13 hybrid condensing dryers only | The drain hose is kinked, crushed or clogged — or the water in the sump is frozen. | Guide → |
| Empty Water water-drop symbol · condenser dryers | The drain container is full, or not correctly inserted — the indicator flickers and the dryer stops. Empty it and click it back in. | Guide → |
| E05 also written E5 | A problem with the water supply used for the steam cycle — tap, inlet hose, inlet filter and inlet valve, in LG's order. | Guide → |
| Add | Add water before a steam cycle: the steam feeder must be filled to the MAX line and the drawer closed. No distilled water. | Guide → |
| nE | A problem with the connection between the control panel and the Wi-Fi module. LG's UK list sends this one to service. | Guide → |
| nF | A problem with the Wi-Fi module itself. LG's UK list sends this one to service. | Guide → |
| CL | A status display — Child Lock (Control Lock) is on: the control panel is disabled and settings cannot be adjusted. | Guide → |
Start with these common codes
Three useful starting points: a venting warning, a door error, and a power-failure code.

Power failure — the factory reset clears most.
The Flow Sense scale, in one place
LG's Flow Sense system estimates exhaust restriction. LG associates d75, d80, d90 and d95 with approximately 75%, 80%, 90% and 95% blockage, respectively. Two or four bars lit on the Flow Sense indicator mean the same thing in bar form — LG's US list calls that a severely restricted exhaust system. LG's Flow Sense guidance is explicit that these are safety alerts, not dryer malfunctions. These warnings usually point to restricted airflow in the exhaust system, including the filter, connecting duct, or exterior vent, and poor venting can make the dryer shut down to prevent overheating. Each level has its own page above, with the checks in LG's order — inside the dryer, behind the dryer, outside the home, then the ducts inside the walls.
Status, maintenance and user-action displays
Four entries in the table — CL, Add, Check Filter and Empty Water — are status, maintenance, or user-action indications rather than necessarily hardware failures; each has its own short guide so a status display is never mistaken for a breakdown. Add is a user-action or water-supply indication, not necessarily a component failure. Check the steam feeder as LG directs. LG's US list explains two more normal displays that need no page of their own, and its full text fits here: Wrinkle Care — when the option is activated it runs at the end of the cycle, tumbling the drum for 10 seconds and then stopping for six minutes, periodically, for up to three hours; opening the door turns it off. Cooling/drying light — the light is normal: a cycle runs a drying portion and then a cooling portion, and the cooling portion does not begin until the last five minutes of the cycle.
Finding your model number
LG's lists differ by model family and region, so your model's own manual is the final word on its codes. The model number is on the rating label — label locations vary by model, commonly inside the door opening or on the back panel. Quote it when you talk to LG service; it decides which list applies to your machine.

Frequently asked questions
Do all LG dryers use the same codes?
Mostly the same letters, but the lists are regional and model-dependent: Flow Sense codes belong to vented dryers, E13 and the Empty Water display belong to condensing models, gAS belongs to gas dryers, and the steam codes (Add, E05) belong to models with steam. Each guide states which machines it applies to.
Where do these meanings come from?
From LG's official support documentation: its US and UK dryer error-code lists, its Flow Sense warning article, and its condenser-dryer Empty Water article. The exact LG pages are linked at the foot of every guide.
My code is not in the table. What now?
Every code and display in the LG sources these guides rest on — LG's published US and UK dryer lists, its Flow Sense article and its condenser-dryer article — has a guide in the table above. If your display shows something that is not there, it may be a code for a different LG appliance (LG reuses letters across appliances — its washer lists are here), an older or region-specific model code, or a misread display (FO is rendered F0 in LG's US list). The settling authority is your model's manual: find the model number on the rating label and enter it into LG's product-support search.

Every meaning and check order on this hub and its guide pages is taken from LG's official support documentation and model manuals, linked at the foot of each guide page. Where LG's regional lists treat a code differently, the guide page says so and prints both. The four lists these guides rest on: LG — Dryer error code list (US) · LG — Dryer error code list (UK) · LG — Flow Sense warning (Canada) · LG — Empty Water Container (Egypt).
