LG Dryer Error Codes: What They Mean and How to Fix Them
What the common LG dryer codes mean, including d80 (blocked vent), dE (door), tE1 (thermistor) and HS (humidity sensor), and what to check first.
An LG dryer reports problems as short codes on the display. Many of them point to something simple like a blocked vent, a lint filter that is not seated or a door that has not latched, and a few point to a part that needs a technician. This guide covers the codes LG lists for its electric dryers, and notes where gas models behave differently.
Start by finding your model number. On a dryer it is usually on a label inside the door opening or on the edge of the door frame. Codes can vary by model and model year, so if yours is not listed here, check the manual for your model.
Lint is a fire hazard: clean the lint filter every load and do not run a dryer with a crushed or blocked vent.
A gas dryer needs a licensed gas technician for any gas supply problem. Do not open the cabinet or touch the cord wiring or terminal block.
Airflow and vent codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| d80 (d75, d90, d95) | The exhaust vent is restricted. | Clean the lint filter, check the duct behind the dryer for kinks and the outside flap for lint. | The codes stay after the vent is clear, or the duct run is long. |
| E13 | The condensate drain hose is blocked or frozen (hybrid condensing models only). | Check the drain hose for kinks, twists and water at the end, then press start. | E13 returns after the hose is clear. |
| F0 | The lint filter is out or not seated. | Remove the lint filter and push it fully back in. | F0 stays with the filter in place. |
LG dryer d80 (d75, d90, d95) error
The d75, d80, d90 and d95 codes tell you how restricted the exhaust is, roughly 75, 80, 90 or 95 percent blocked. Clean the lint filter, make sure the duct behind the dryer is not crushed or kinked, and check that the flap on the outside vent opens fully and is free of lint. If the vent is clear and the code stays, or the duct run is long with many bends, a technician can look at the dryer itself. A gas dryer showing this code with a clear vent needs a licensed gas technician, because we do not service gas appliances.
Model note: LG notes that on gas dryers a d80 display can also point to a lack of gas supplied to the unit. We only service electric dryers.
LG dryer E13 error
E13 only appears on hybrid condensing dryers. It means the drain hose is kinked, crushed or clogged, or that the water in the sump has frozen. Straighten the hose, make sure water is not sitting at the end of it, and use the standard hose rather than an extended one. If E13 comes back after pressing start, the dryer needs service.
Model note: Hybrid condensing models only.
LG dryer F0 error
F0, or a flashing INSERT FILTER message, means the dryer does not sense its lint filter. Pull the filter out, clear off any lint and slide it all the way back into the housing. If the message continues with the filter seated, the sensor may need a technician.

Door and power codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| dE | The door is not completely closed. | Check the lint filter is pushed in and nothing is caught in the door, then do a power reset. | dE returns after a reset. |
| nP | No current is detected at the heater. | Turn the dryer breaker off for 10 seconds and back on, and check the cord is firmly plugged in. | The dryer still does not heat. |
| PS | Improper voltage at the power cord. | Confirm the cord is firmly plugged in, then turn the breaker off for 10 seconds. | PS shows on a new install, or returns after the breaker reset. |
| PF | Power was interrupted, often by an outage. | Do the power reset below, then run a cycle. | PF persists after the reset. |
LG dryer dE error
dE is the door error. Open the door, make sure the lint filter is pushed all the way in and nothing is caught on the door, then close it firmly. If that does not clear it, unplug the dryer or trip its breaker, wait a few seconds, then restore power, shut the door and start any cycle. A bent door or a repeat of dE means the dryer needs service.
LG dryer nP error
nP means the dryer is not seeing current at the heater, which usually points to a problem with the home wiring or the outlet. Make sure the cord is firmly plugged in, then switch the dryer breaker off for at least ten seconds and back on. If it still does not heat, the outlet may need an electrician's check, or the dryer needs a technician.
LG dryer PS error
PS means the dryer detected an improper voltage in the power cord. Make sure the cord is plugged in securely, then switch the dryer breaker off for ten seconds and back on. If the dryer was just installed, have the installer recheck the cord connection and outlet, because cord wiring should not be touched by a homeowner.
LG dryer PF error
PF often appears after a power outage. The usual fix is the control reset described below. If PF keeps returning without an outage, the dryer needs service.
Sensor and temperature codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| HS | The humidity sensor has an error. | Wipe the sensor strips below the lint filter with a damp cloth and let them dry. | HS persists after cleaning. |
| tE1 (tE3) | A thermistor (temperature sensor) problem. | Do the power reset below. | The code persists after the reset. |
| tE2 | A thermistor error, usually in cold conditions or with steam cycles. | Power the dryer off, then back on, and retry; for steam cycles follow the model instructions. | tE2 returns after a reset. |
LG dryer HS error
HS points to the humidity sensor, which tells the dryer when clothes are dry. With HS showing, the dryer runs for about two and a half hours, so it can look like it is not drying. Clean the sensor strips inside the drum, below the lint filter, with a damp cloth or paper towel, and let them dry fully before the next cycle. If HS persists after cleaning, book a repair.
LG dryer tE1 (tE3) error
tE1 and tE3 mean the dryer found a problem with its thermistor, the part that reads drum temperature. LG's usual fix is the control reset described below. If the code returns after the reset, the thermistor or its wiring needs a technician.
LG dryer tE2 error
tE2 is also a thermistor code, but it tends to show in cold conditions. On steam models, the extra moisture in a steam cycle can cool the duct quickly and trigger it. Reset the dryer and try again, and if tE2 keeps appearing the dryer needs service.
Model note: LG's page gives a model-specific button sequence for steam cycles; check your manual.
Messages that are not faults
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| CL | Child lock is on. | Hold the child lock key for 3 seconds. | Nothing needed, it is not a fault. |
| Add | The steam feeder needs water. | Fill the steam feeder to the max line with tap water and close the drawer. | Add stays after filling the feeder. |
LG dryer CL error
CL is not a fault. It shows the child lock, also called control lock, is on, so the buttons do nothing on most models. Press and hold the child lock key for three seconds to turn it off.
LG dryer Add error
Add appears on steam models when the steam feeder is empty. Fill it with tap water up to the max line, not distilled water, and make sure the drawer is fully closed. If Add appears mid-cycle, pause, fill it, then power off and on and restart the steam cycle.
Model note: Steam models only.
How to reset your LG dryer
LG documents a control reset that clears several of these codes. It involves cutting power, holding the start button, and restoring power.
- Unplug the dryer or switch off its circuit breaker.
- With the power off, press and hold START/PAUSE for 5 seconds.
- Restore power and try a cycle.
Frequently asked questions
What does d80 mean on my LG dryer?
d80 means the exhaust vent is restricted, about 80 percent blocked. Clean the lint filter and check the duct and the outside flap. If a gas dryer shows it with a clear vent, a licensed gas technician must check the gas supply.
What does dE mean on my LG dryer?
dE is the door error: the dryer does not think the door is fully closed. Check the lint filter is pushed in and nothing is caught in the door. If it persists after a power reset, the door switch or latch may need repair.
What does HS mean on my LG dryer?
HS is a humidity sensor error, and it makes the dryer run for about two and a half hours. Wipe the sensor strips below the lint filter with a damp cloth and let them dry. If it returns, book a repair.
What does tE1 mean on my LG dryer?
tE1 (and tE3) points to the thermistor, the temperature sensor. Try the control reset first. If the code comes back, the sensor needs a technician.
