d80, d90, or d95 Error Code

LG dryers have incorporated error codes that can display along with the Flowsense™ indicator. When one of these errors display, this indicates that the dryer's exhaust system is not moving enough air from the dryer to the outside of the home.

The d80, d90, and d95 error codes indicate that the dryer's exhaust duct is clogged 80%, 90%, or 95% respectively. This is most often the result of lint buildup somewhere in the exhaust duct.

If a d80, d90, or d95 error code appears on the dryer's display, the dryer will shut off automatically after 2 minutes. A warning sound will be heard from the dryer periodically.

To resolve this error code, follow the quick tips the troubleshooting steps below.

  1. What type of dryer do you have?

    Gas Electric
  2. Let's try something to find out which meaning the code has for your unit.

    1. Power the unit ON.

    2. Press the TIMED DRY button one time to select manual dry.

    3. Press the TEMP. button until the highest temperature is selected.

    4. Press START/PAUSE.

    5. Allow the dryer to run for 1 minute.

    Is the inside of the dryer warm?

    Yes No
  3. This means the dryer is working correctly, the exhaust system should be inspected and cleaned. You may need to contact a local chimney cleaning company.

    1. Check gas connection

    2. Check gas valve

    3. Pinched gas line

    4. Check other appliance

      Check to ensure that the other gas appliances in the house are working, such as a gas stove.

    After doing the checks above, is the dryer working properly?

    Yes No
  4. Great! It seems the issue is fixed. For your convenience, please refer to our help library article on Not Heating - Not Drying - Long Time Drying for more information.

  5. The dryer is not operating as it should. The unit will require a repair service. Please visit our Request a Repair page.

  6. The quickest and easiest way to troubleshoot these codes is to disconnect the dryer vent and run a load of wet clothes. If the load dries as it should, then the problem resides in your home exhaust system. If the load is still wet, then the dryer may require service.

    1. Test without exhaust duct

      To get started, you will need a sheer, nylon stocking (to collect lint), medium sized rubberband, and a load of wet laundry.

      • Unplug the dryer from the wall outlet.

      • Remove the vent duct from the back of the dryer.

      • Place the stocking over the outlet duct and secure with rubberband.

      • Plug the unit back in, clean the lint filter, and load the wet laundry into the dryer.

      • Select the TIMED DRY cycle for 30 Minutes and press START.

      • If the load is Dry - The vent must be checked for restrictions by a local vent or chimney cleaning company.

      • If the load is Wet - Your dryer will require service. For your convenience, you can request a repair online using our Request a Repair page.

    2. Lint Buildup

      Check for lint buildup at the rear exhaust duct, the lint build up will cause a long time drying in the dryer.

      If you need the service of a professional technician, contact a local chimney cleaning company to clean the vent.

    3. Damaged Exhaust

      A crushed or damaged exhaust will also cause air blockage. If possible, check every section of your exhaust duct to ensure it is not crushed, kinked or damaged.

    4. Crushed duct

      • Avoid long runs or runs with multiple elbows or bends.

      • Excess or crushed transition duct.

      • Too many elbows or exhaust too long can also cause long time drying.

    5. Ductwork is too long

      When the ductwork is too long or has too many bends, blockages can occur, and it will be hard to trace. In this case, check the exterior part of the house when the machine is running to see if exhaust air is blowing outside.

      For proper inspection and repair of this situation, contact a local chimney cleaning company to clean the vent.

dE (Door Error)

A DE error code means that the dryer door is not completely closed. This might be a result of:

  • Door not completely closed.


    Open the door and make sure the filter is pushed all the way in and that there are no articles of clothing stuck on the door


  • Door Misaligned.

    If the unit is brand new, is there any noticeable damage or the frame of the unit (such as the door bent)? If so, please contact the dealer.

    If the problem is not a dent or damage, please try the following:

      1. Reset the unit by unplugging it from power, or trip the circuit breaker.
      2. Wait 5 sec.
      3. Plug unit back in.
      4. Close door firmly.
      5. Select any cycle and press Start.
      6. If the unit gives the code again, the unit will need service.

E13 Error Code

An E13 error code on the dryer's display indicates that the drain hose is kinked, crushed, clogged, or that the water in the sump is frozen.

Note: The E13 error code will only display on Hybrid Condensing Dryers.

If the E13 error code is showing on the dryer's display:

  1. Check that the drain hose is not kinked, twisted, or clogged with water at the end of the hose.
  2. If the drain hose was extended, the dryer will not drain well because of the increased resistance. It is recommended to only use the standard LG drain hose.
  3. Press the START/PAUSE button to start the dryer again after checking that the drain hose is not kinked, twisted, or clogged.

If the E13 error code occurs again, the unit will require a repair service. Please visit our Request a Repair page.

FO (Filter Out) Display

An FO error or a flashing INSERT FILTER on the dryer's display indicates that the lint filter should be checked to ensure that it is inserted properly.

fo error

When the lint filter is not inserted properly, the sensor inside the dryer will display FO, and the dryer will stop working. Remove the lint filter and reinsert it into the lint filter housing.

lint filter placement

If the error continues to appear on the display screen, the unit may require a repair service. Please visit our Request a Repair page.

HS Error Code

HS error code on the dryer's display indicates that the dryer has detected an error with the HUMIDITY SENSOR.

The HS error code will cause the dryer to run for 21/2 hours, which may seem as though the dryer is not drying.

If the HS error is displayed, clean the sensors on the inside of the dryer, located below the lint filter. Allow the sensors to fully dry before attempting another cycle.

If the HS error code persists, the unit may require a repair service. Please visit our Request a Repair page.

nP Error Code

A nP error code on the dryer's display indicates that there is a problem with the electrical wiring in the home, and that no current is being detected at the heater.

If the nP error is displaying, the home's outlet may need to be checked by a licensed electrician in order to ensure that the correct voltage is supplied to the dryer.

PF Error Code

This usually happens after a power outage. To fix it, we're going to do a factory reset.

  1. Unplug the dryer or trip the circuit breaker supplying power to the dryer off.

  2. While the dryer is without power, press and hold the Start/Pause button for 5 sec.

  3. Restore power and try to run a cycle.

If the PF error code persists, the unit may require a repair service. Please visit our Request a Repair page.

PS Error Code

A PS error code on the dryer's display indicates that there is improper voltage with the power cord, which could be caused by the white and red wire connections being reversed on the dryer's terminal block. If the unit was just installed, you should call the installer to have them check the power cord installation and the wall outlet.

Refer to the owner's manual for the applicable model for installation instructions for the dryer's power cord.

tE1 Error Code

A tE1 error code on the display of the dryer indicates a problem was detected with the dryer's thermistor. If the tE1 error code is showing on the dryer's display:

  1. Unplug the dryer, or trip the circuit breaker supplying power to the dryer.

  2. While the dryer remains without power, press and hold the START/PAUSE button for 5 seconds.

  3. Restore power to the dryer and attempt to run another cycle.

If the tE1 error code occurs again after resetting the dryer, the unit may require a repair service. Please visit our Request a Repair page.

tE2 Error Code

A tE2 error code on the display of the dryer indicates a problem was detected with the dryer's thermistor, normally during cold conditions. The extra humidity in the dryer's vent during the SteamFresh™, Steam Sanitary™, or Steam Option cycles cause the duct to cool down faster, resulting in the dryer displaying the tE2 error.

If the tE2 error code is showing on the dryer's display during the SteamFresh™, SteamSanitary™, or the Steam option:

  1. Power the dryer ON.

  2. Select the SteamFresh™ cycle.

  3. Press the MORE TIME button until big is shown in the display.

  4. Press the START button.

Cycle Selection

If the tE2 error code occurs again after resetting the dryer, the unit may require a repair service. Please visit our Request a Repair page.

tE3 Error Code

A tE3 error code on the display of the dryer indicates a problem was detected with the dryer's thermistor. If the tE3 error code is showing on the dryer's display:

  1. Unplug the dryer, or trip the circuit breaker supplying power to the dryer.

  2. While the dryer remains without power, press and hold the START/PAUSE button for 5 seconds.

  3. Restore power to the dryer and try to run another cycle.

If the tE3 error code occurs again after resetting the dryer, the unit may require a repair service. Please visit our Request a Repair page.

Add (Add Water)

An Add Water error reading on the dryer's display indicates that there is a water supply error.

Before using a steam cycle, the steam feeder must be filled with water up to the MAX indicator lines. Check the steam feeder to be sure that it is full of water and that the drawer is completely closed.

Note: Do not use distilled water in the steam feeder drawer

If the Add Water reading appears on the dryer's display after a cycle has started:

  1. Press PAUSE to temporarily stop the running cycle.

  2. Fill the steam feeder with tap water to the MAX fill line.

  3. Power the unit off and back on again, select the STEAM cycle, and press the START/PAUSE button to finish the cycle.

Check Filter

Check filter is not an error, it was designed to serve as a reminder to clean the lint filter before each use to ensure great drying every time.

The indicator turns off when you turn the cycle knob to select a drying program or when the START/PAUSE button is pressed.

CL (Child Lock)

A CL code or CHILD LOCK reading on the dryer's display is not actually an error code, but rather an indication that the Child Lock feature is active.

For most models, press and hold the key labeled CHILD LOCK for 3 seconds to disable the Child Lock feature.

Note: When the child lock feature is active, the control panel is disabled and settings cannot be adjusted.

Cooling / Drying Light

This is normal. The machine runs a dry portion and cooling portion of the cycle. The cooling portion of the cycle does not begin until the last 5 minutes of the cycle.

Flow Sense Indicator

FlowSense™ is a feature on some LG model dryers which uses existing components in dryers to calculate the amount of restriction in the drying system.

  • If no indicator bars are lighted in the display, exhaust duct condition is very good. The customer can expect high efficiency and the shortest possible dry times.

    • If two bars in the display are lit, examine the dryer exhaust system for lint build up or other restrictions, including damage, excess length, foreign objects, etc.

    • Once the duct has been checked, cleaned, and/or repaired, it will take 2 or 3 full cycles for the control to detect that the system has been improved.

    • If the unit originally had no bars displayed and later experiences a 2-bar display, the display should return to no bars once the system is cleaned or repaired.

    • If 2 bar display from the beginning, it does not mean that the dryer will not work properly. Once the system is checked for lint buildup, length, damage, etc., it may still have two bars showing. This simply indicates that the exhaust system is less than ideal but still adequate.

    • Using the dryer with two bars showing will not harm the dryer in any way. It is simply the control's way of indicating to the customer that they may experience somewhat reduced efficiency and slightly longer dry times. For that customer, then, two bars becomes the normal display.

    • A 4-bar display indicates that the exhaust duct is inadequate for normal operation of the dryer.

    • This will in no way prevent using the dryer, but it will experience greatly reduced efficiency and much longer dry times.

    • Once the duct is repaired, the display should return to its former level, i.e. two bars or no bars. In this case, it is important that the exhaust system is checked for excess lint buildup or foreign object restriction. It should also be checked for damaged/crushed ductwork and excessive length, in which case repairs should be made in addition to cleaning.

Wrinkle Care

This display is not an error code and does not indicate that there is a problem with the dryer. When activated, wrinkle care functions at the end of the drying cycle and will continue to tumble the dryer drum to prevent wrinkles.

The drum will rotate for 10 seconds and then off for 6 minutes. It will run for up to 3 hours. If the door is opened during this time, the Wrinkle Care option will turn off.

Reset the Control Panel

If you need to reset the Control Panel

  1. Power the dryer OFF and unplug it from the electrical outlet (You can also trip the circuit breaker if that's easier).

  2. Press and hold the START/PAUSE key for 5 seconds while the unit is without power.

  3. Turn the breaker back on, and power on the unit.
