LG dryer error code D80: What it means and how to clear it

It's laundry day, and you have a mountain of clothes to wash. You transfer the first load to your LG® dryer and push start. Instead of tumbling your wet T-shirts and jeans, the display shows LG dryer code D80. What does that mean?

Asurion Experts keeps your home appliances running smoothly. Whether you're experiencing dryer start issues or spinning issues, we have a solution you can trust. Here's how to clear the D80 code on an LG dryer and when to call a technician.

Understanding the D80 error code

First — what is the D80 code on LG dryers? 

LG dryers have roughly two dozen codes used to alert owners to machine problems. A D80 code means your dryer doesn't have enough airflow to do its job. You may notice the dryer getting too hot when it's in use. A buildup of lint or moisture inside the dryer's lint trap or ductwork can generate the error. Other potential causes include improperly designed dryer ducting or a crushed conduit. 

The D80 code signifies an 80% blockage within the dryer ducts. Similar codes include D90 and D95, which indicate a 90% or 95% blockage. An LG dryer with a D90 or D95 code may shut down automatically to prevent damage to the appliance.

Follow these instructions to clear the D80 error

Too much lint buildup puts the dryer at risk of fire and overheating. Take action to remove clogs before attempting to dry your clothes. 

1. Clean the lint filter

Remove the dryer lint tray from the dryer and discard any lint attached to its surface. Use a soft brush and warm water to gently clean the tray. Allow it to dry completely before reinserting it into the appliance.  

2. Inspect the exhaust hose for damage

Unplug the dryer from its power source. Pull it away from the wall and locate the silver-colored exhaust hose in the back. Verify the hose is straight or shaped like an S. A bent or coiled exhaust hose may reduce airflow to the dryer. Confirm there are no rips or compressions to the hose. If there are, you may need to replace them. 

3. Check the exhaust hose for obstructions

Detach the hose from the back of the dryer. You may need to unscrew it from the appliance using a screwdriver.

Pull any immediately visible lint clogs from the hose with your fingers. Then, use a vacuum to drag backed-up lint toward the front of the hose and remove it. Your vacuum's crevice attachment can help with this task.

After removing any built-up lint, reattach the exhaust hose to the dryer. Leave it unplugged from the power source for now. 

4. Verify the exhaust duct is clear

Most homes have an outside exhaust duct, usually on an exterior wall near the dryer hook-up area. Locate yours and use a vacuum to remove built-up grime and lint around the cover. Then, use a flashlight to peer into the exhaust pipe and locate any visible clogs.

A power shop vacuum can extract larger obstructions you can't reach. If you have one available, use its crevice attachments to loosen clogs and pull them toward the wall duct opening. Remove and discard the lint in the trash. 

You can plug the dryer into its power source after removing the clogs. The error message should go away. 

When to call a professional

If the D80 code continues to appear, the dryer may have an interior ventilation blockage beyond your reach. Before attempting to use your appliance again, call an experienced expert to perform a dryer diagnostic test on its ventilation sources. Look for a contractor in your area who specializes in LG dryer heating issues. An HVAC technician may also be able to help.
