LG dryer error codes

Scroll down through this alphabetical list of LG error codes to find the one you’re experiencing. Learn what it means and how to resolve it.

Add

If your dryer’s display says “Add,” water needs to be added to the steam feeder so it can run a steam cycle. Make sure it’s filled up to the MAX line and that the drawer is fully closed. Use regular tap water, not distilled water.

Check Filter (blinking light)

The “Check Filter” light blinks to remind you to clean the filter. It’s not an error. Cleaning the filter after each load helps ensure your dryer stays in good working order.

Child Lock (CL)

If your dryer’s display shows “CL” or “CHILD LOCK,” the Child Lock feature is turned on. On most models, you can turn it off by pressing and holding the “CHILD LOCK” button for about 3 seconds.

Cool or Dry (blinking lights)

It’s normal for the “Cool” or “Dry” light to blink on the display—your dryer switches between drying and cooling during the cycle.

d80, d90, and d95

If your dryer is displaying one of these error codes, an airflow blockage has likely occurred at some point between the dryer and the outside vent.

Try the following to resolve the error code:

• Clean the lint filter after each load.
• Thoroughly clean with a soft brush and warm water. Let it dry before reinstalling.
• Try reducing the load size for better airflow.
• Make sure the exhaust hose isn’t crushed, bent, or kinked.
• Check for holes in the hose or loose connections.
• Check that the dryer vent hood on the exterior of your home isn’t clogged with debris and that the flappers can open fully.
• Clean the dryer vent yourself or hire a professional vent cleaning service.

dE

A dE error code means your dryer door isn’t fully closed. Try opening and firmly closing the door. Also, ensure the lint filter is pushed all the way in and that no laundry items are caught in the door.

dHE error code

A dHE error code indicates the dryer had a temporary issue. Unplug it, wait 10 seconds, plug it back in, and restart the cycle.

E05

The E5 error code indicates that an issue has occurred with the water supply for the steam cycle. Try the following:

• Make sure the water tap isn’t clogged, frozen, or partially closed—keep it fully open.
• Inspect the water inlet valve.
• Inspect the inlet hose.
• Clean the inlet filter.

E21

The E21 error means there’s a problem with the drain pump. If you’re using a washer-dryer combo, this shows up when the tub is draining slower than it should—usually because something’s blocking the drain line.

Try the following to resolve it:

• Make sure the drain hose isn’t kinked.
• Check the drain hose for any clogs.
• Clean out the drain pump filter.

FO

If you see an FO error or “INSERT FILTER” flashing on your dryer, the lint filter isn’t properly in place. Try removing it and then reinserting it.

gAS

A gAS error code indicates your dryer isn’t getting any gas. You should:

• Make sure the gas supply valve is fully open.
• Inspect the gas line to ensure it’s not kinked.
• Consider a repair service.

HS

An HS error means there’s an issue with the humidity sensor. To resolve this, clean the humidity sensors inside the dryer, located just below the lint filter, and let them dry completely before starting another cycle.

nE or nF

The nE error indicates a connection issue exists between the control panel and the Wi-Fi module, while the nF error points to a problem with the Wi-Fi module itself. These issues usually need a professional service to fix.

nP

The nP error means the dryer isn’t detecting power at the heater, usually due to an issue with the home’s electrical wiring. You can try the following:

1. Ensure the power cord is plugged into a 240V grounded outlet that matches the dryer’s rating.
2. Turn off the dryer’s circuit breaker at the main panel for at least 10 seconds, then switch it back on.
3. Check the outlet is supplying the right voltage with a multimeter. Hire an electrician if there’s a problem.

PF

This usually happens after a power outage, but a quick reset can help.

1. Unplug the dryer or turn off its circuit breaker.
2. While the power is off, press and hold the Start/Pause button for 5 seconds.
3. Plug the dryer back in or turn the breaker back on, then try running a cycle.

Reset Control Panel

If you’re seeing this error, you’ll need to reset the control panel.

1. Turn off the dryer and unplug it from the outlet.
2. With the dryer unplugged, press and hold the START/PAUSE button for 5 seconds.
3. Plug the dryer back in, then power up the unit.

tE1

If your dryer’s showing a tE1 error, a problem has occurred with the thermistor (the component that helps control temperature).

First, try doing a factory reset—that might clear the error. If the error persists, have a professional repair your appliance.

tE2

If you’re seeing a tE2 error on your dryer’s display, a problem with the thermistor was detected. This error usually occurs in colder winter conditions. It can happen when using any Steam option, as the duct may be cooling down too fast.

You can try the following to resolve it:

• Clean the lint filter.
• Clean the vent system, or have a professional do it.
• Make sure ice or snow isn’t blocking the exterior vent hood.
• Run the dryer while it’s empty for a few minutes on a different cycle to warm it up.

tE3

The FE error means your washer is filling with too much water, usually due to a faulty water valve. Following these steps may resolve it:

1. Turn off both water supply valves.
2. Drain the excess water by repeatedly pressing the Spin Speed button until No Spin is selected, then hit START/PAUSE.
3. Once drained, try running a new wash cycle.

If the error comes back, your washer may need professional repair.
