LG Appliance Error Codes: Complete Troubleshooting Guide
Your LG appliance just flashed a code on the display, and now you're wondering what it means and whether you need to call a technician. You're not alone. LG builds error code diagnostics into all of their major appliances, from refrigerators and washers to dryers, dishwashers, and ovens. These codes are designed to help you (or your repair technician) identify what's going wrong so the problem gets fixed faster.
In this guide, we break down the most common LG error codes by appliance type, explain what each one means, and walk you through the troubleshooting steps you can try at home before booking a service call. Some codes point to simple checks homeowners can safely perform. Others involve internal electrical, mechanical or gas components that should be diagnosed by a qualified technician. We'll tell you which is which.
At EasyFix Appliance Repair, our technicians diagnose and repair LG appliances every week across Greater Vancouver and Victoria, BC. We've compiled this guide from hands-on experience with real LG error codes in real homes.
Important: LG error codes and troubleshooting procedures can vary by appliance type and model. The codes below cover common meanings, but always check LG's official support information or the owner's manual for your specific model before troubleshooting.

How to Read LG Error Codes
LG error codes typically appear as two-character alphanumeric combinations on the digital display panel. Error-code formats vary by appliance type and model. Some use two-character codes such as IE or OE, while others use combinations such as ER FF, d90, or F9.
If your LG appliance doesn't show a code automatically, you can often pull up hidden diagnostic codes. Diagnostic procedures vary by model. Check the owner's manual or LG's support information for your exact model before attempting to enter a diagnostic mode. For washers and dryers, the method varies by model, so check your owner's manual.
LG Washer Error Codes
LG washers are among the most popular laundry appliances in Canadian homes, and they're generally reliable. But when something goes wrong, the control panel will display an error code to tell you what happened. Here are the codes our technicians see most often when servicing washers across the Lower Mainland.
For model-specific code definitions and troubleshooting steps, refer to LG's official washer error-code information or the owner's manual for your appliance.| Code | What It Means | What to Try | Level |
|---|---|---|---|
| IE | Water not filling properly (inlet error) | Check that the water supply valves behind the washer are fully open. Inspect the inlet hoses for kinks. Clean the inlet filter screens on the back of the washer. | DIY Fix |
| OE | Water not draining (outlet error) | Check the drain hose for kinks or clogs. Clean the drain pump filter (located at the bottom-front of front-load models). Make sure the drain hose isn't inserted more than 8 inches into the standpipe. | DIY Fix |
| UE / uE | Unbalanced load detected | Open the door and redistribute the laundry evenly. Avoid washing single bulky items (like a comforter) alone. A lowercase "u" means the washer is trying to rebalance itself; uppercase "U" means it gave up. | DIY Fix |
| LE | Motor/tub rotation error | Reduce the load and check for any foreign object interfering with tub movement. Unplug the washer, wait about 5 minutes, then restart it. If LE returns with a normal load and no obstruction is present, professional diagnosis may be needed. | Try DIY First |
| DE | Door is not locked properly | Make sure nothing is caught in the door seal. Close the door firmly until you hear the lock click. Wipe the door latch and gasket area clean. | DIY Fix |
| FE | Overfill error (too much water) | Unplug the washer. Check whether water continues to flow in, which would indicate a stuck inlet valve. If water stops, reset and try again. If water keeps flowing, the inlet valve needs to be replaced by a technician. | Call a Pro |
| PE | Water level sensor failure | Unplug the washer for 10 seconds and restart. If the code persists, the pressure switch or its wiring needs professional diagnosis. | Call a Pro |
| PF | Power failure during cycle | This simply means the power was interrupted mid-cycle (from a power outage or the plug being bumped). Press Start to resume the cycle. | DIY Fix |
| tCL | Tub clean cycle reminder | Not an error. LG is reminding you to run the Tub Clean cycle. Run the Tub Clean cycle according to the instructions for your model. LG recommends regular tub cleaning to help control residue and odours. | Maintenance |
IE and OE are among the washer codes our technicians encounter regularly. In most cases, the fix is straightforward: a kinked hose, a clogged filter, or a water supply valve that wasn't fully opened. Check those first before assuming the worst.
LG Dryer Error Codes
LG dryers use a system called Flow Sense to monitor exhaust airflow. When your vent gets clogged (and it will over time), the dryer tells you with a specific code. This is actually a safety feature, since Restricted dryer venting reduces airflow, increases drying time, and can create a fire risk. If your dryer is taking forever to dry clothes, check for these codes.
LG's Flow Sense system can display airflow-related codes when the dryer detects restricted exhaust airflow. For model-specific codes and troubleshooting, refer to LG's official dryer support information.
| Code | What It Means | What to Try | Level |
|---|---|---|---|
| D80 | Exhaust duct 80% blocked | Clean the lint filter thoroughly. Disconnect the exhaust hose from the back and check for lint buildup. Check the exterior vent flap for blockage. The dryer will still run, but this is a warning. | DIY Fix |
| D90 | Exhaust duct 90% blocked | Same steps as D80, but more urgent. At this level, the dryer may shut down mid-cycle to prevent overheating. You likely need to clean the entire vent run from the dryer to the exterior wall. | Try DIY First |
| D95 | Exhaust duct 95% blocked (critical) | Stop using the dryer immediately. The vent system is almost completely blocked. A professional dryer vent cleaning is strongly recommended at this point. | Call a Pro |
| nP | No power to heater (electric dryers) | Check that the dryer is plugged into a 240V outlet (not 120V). Reset the circuit breaker for 10 seconds. If the code persists, the home outlet may need to be inspected by an electrician. | Call a Pro |
| PS | Power cord wiring issue | The wires inside the power cord terminal block may be reversed (red and white swapped). If the dryer was recently installed, have the installer recheck the wiring. | Call a Pro |
| tE1 / tE2 | Thermistor/temperature-sensing error | Disconnect power to the dryer, follow the reset procedure for your model, and restart it. If the tE code returns, professional diagnosis may be needed. | Call a Pro |
| dE | Door not fully closed | Open and firmly re-close the door. Make sure the lint filter is pushed all the way in. Check for clothing caught in the door seal. | DIY Fix |
| HS | Humidity sensor error | Clean the sensor bars inside the drum (located below the lint filter) with a damp cloth. Allow them to dry completely before running another cycle. | DIY Fix |
| CL | Child Lock activated | Not an error. Press and hold the Temp and Time buttons simultaneously for 3 seconds to deactivate the Child Lock. | DIY Fix |
| PF | Power failure or interruption occurred during operation | The code can appear after a power outage or interruption. Reset the dryer according to the instructions for your model and restart the cycle. If the PF code continues to return without an apparent power interruption, further diagnosis may be needed. | Call a Pro |
LG Refrigerator Error Codes
LG refrigerators display error codes on the front panel, usually preceded by "ER" or "E". Some codes appear automatically when a problem is detected, If your fridge isn't cooling properly, checking for error codes is the first step. Our refrigerator repair technicians troubleshoot these codes daily.
LG refrigerator error codes vary by model and refrigerator type. Check LG's official refrigerator error-code information
or your model's owner's manual to confirm the meaning of a specific code.
| Code | What It Means | What to Try | Level |
|---|---|---|---|
| ER FF | Freezer fan motor failure | This is often caused by frost buildup around the fan. Unplug the fridge, remove all food, leave the doors open, and let it defrost for 8 hours. Wipe dry, plug back in, and wait 24 hours. If the code returns, the fan motor needs replacement. | Try DIY First |
| ER rF | Refrigerator compartment fan failure | Same approach as ER FF. Defrost the unit for 8 hours. If ice was blocking the fan, this should resolve it. If not, the fan motor itself is likely faulty. | Try DIY First |
| ER CF | Condenser fan failure | The condenser fan (usually at the back or bottom) isn't spinning. Unplug the fridge, pull it away from the wall, and check for dust or debris around the fan. Clean the area and try again. If the fan still won't spin, it needs to be replaced. | Call a Pro |
| ER CO | Communication error (main board to display) | Unplug the fridge for 60 seconds and plug it back in. If the code persists, there may be a wiring issue or a faulty control board that requires professional diagnosis. | Call a Pro |
| ER IF | Ice maker fan issue | The ice maker's fan motor or sensor is malfunctioning. Try unplugging for 60 seconds. If it returns, this typically requires a technician to replace the fan assembly. | Call a Pro |
| ER IS | Ice maker sensor disconnected | Unplug and reconnect after 60 seconds. This code usually indicates a loose connection or a failed ice maker sensor that a technician will need to address. | Call a Pro |
| ER DH | Defrost heater issue | The defrost heater isn't working properly, which will lead to frost buildup and poor cooling. This requires professional repair to replace the defrost heater or timer. | Call a Pro |
| ER gF | Water flow sensor malfunction | Check that the water supply valve is open and the water line isn't kinked. Unplug the fridge for 60 seconds. If the code persists, the water inlet valve or flow sensor may need replacement. | Try DIY First |
| 22 | Compressor-related error on applicable LG refrigerator models | Reset power to the refrigerator according to the instructions for your model. If the code returns or the refrigerator is not cooling properly, professional diagnosis is recommended. | Call a Pro |
The ER FF (freezer fan) code is the most common refrigerator code we encounter. In some cases we see, a thorough defrost temporarily resolves the code when frost is obstructing the fan. The frost melts, the fan spins freely again, and the fridge goes back to normal. But if the code comes back within a few weeks, that usually means the defrost system itself has a problem, and the frost will keep building up until the root cause is fixed.
LG Dishwasher Error Codes
LG dishwashers are generally straightforward when it comes to error codes. IE, OE and AE/E1 are common codes worth understanding because they point to fill, drain and leak-related problems. If you're dealing with a dishwasher that isn't draining or won't fill, check these codes first.
LG dishwasher error codes can vary by model. Check LG Dishwasher OE Error and Troubleshooting
or your owner's manual to confirm the code before troubleshooting.
| Code | What It Means | What to Try | Level |
|---|---|---|---|
| IE | Water not filling (inlet error) | Make sure the water supply valve under the sink is fully open. Check for kinks in the supply hose. Clean the filter screen on the water inlet valve. Water pressure should be at least 20 PSI. | DIY Fix |
| OE | Water not draining (outlet error) | Clean the drain filter at the bottom of the dishwasher. Check the drain hose for kinks. If connected to a garbage disposal, make sure the knockout plug has been removed. Run the disposal to clear any blockage. | DIY Fix |
| AE / E1 | Leak detected (flood switch triggered) | Stop the dishwasher and check for visible signs of leaking around the unit. Make sure the dishwasher is level and inspect accessible hoses and connections for obvious leaks. If the code remains or water is leaking from underneath the appliance, stop using it and arrange professional diagnosis. | Try DIY First |
| FE | Overfill error (too much water) | The dishwasher's drain pump will run automatically. Unplug the unit and check if water continues to enter, which means a stuck inlet valve. If water stops, reset and run a cycle. If it keeps filling, the inlet valve needs replacement. | Call a Pro |
| HE | Heater error (water not heating) | Turn off the dishwasher and circuit breaker for 10 seconds. Turn it back on and start a new cycle. If the code persists, the heating element or control board may need professional attention. | Call a Pro |
| LE / CE | Motor error | This may indicate a problem with the wash motor or the wiring harness. Try resetting the power for 10 seconds. If the code returns, the motor or control board likely needs repair. | Call a Pro |
| tE | Temperature sensor failure | The thermistor is reading abnormal temperatures. This code requires professional service to replace the sensor or inspect the control board. | Call a Pro |
| bE | Excessive suds (bubble error) | Use only dishwasher-specific detergent. If excessive suds are present, stop adding detergent and follow LG's model-specific instructions for clearing the condition. | DIY Fix |
LG Oven & Range Error Codes
LG oven and range error codes use an "F" prefix followed by a number. These codes can indicate anything from a minor sensor glitch to a serious heating failure. If your stove or oven is displaying an F code, here's what to do.
LG range and oven error-code meanings can vary by model and range type. Confirm the code using LG's official support information for your specific appliance before replacing parts.
| Code | What It Means | What to Try | Level |
|---|---|---|---|
| F1 | Oven temperature sensor error | Press Clear/Off and try again. If the code returns, turn off the circuit breaker for 30 seconds. An F1 usually means the temperature sensor (thermistor) is giving bad readings and may need replacement. | Try DIY First |
| F2 | Oven temperature sensor error (secondary) | Same as F1. Press Clear/Off, then reset the breaker. Check the sensor probe for visible damage or loose wiring. If the code persists, the sensor or control board may need professional service. | Call a Pro |
| F3 | Touchpad / keypad sensor error | A button on the control panel may be stuck. Press each button to check for responsiveness. Reset the breaker for 30 seconds. If the code persists, the touchpad membrane or control board likely needs replacement. | Call a Pro |
| F9 | Oven not heating properly | The oven failed to reach 150°F within 5 minutes of preheating. Press Clear/Off and reset the breaker. On gas ranges, this often points to a weak or failing igniter. On electric models, the heating element or relay board may be the issue. | Call a Pro |
| F10 | Upper oven door-locking system failure on applicable models | Press Clear/Off and retry the function. If the code returns after resetting power, professional service may be needed. | Call a Pro |
| F11 | Communication error between boards | Reset the breaker for 30 seconds. This code typically indicates a failed connection between the main control board and the display board, and usually requires professional diagnosis. | Call a Pro |
| PF | Power failure | A power interruption occurred. Press Clear/Off and restart your cooking cycle. No repair needed. | DIY Fix |
| Sb | Sabbath Mode active | Not an error. The oven is in Sabbath Mode. Refer to your owner's manual for instructions on deactivating it, as the steps vary by model. | DIY Fix |
On some LG gas ranges, an F9 heating fault can be associated with an ignition problem. A weak igniter is one possible cause, but the actual cause can vary by model and should be diagnosed before parts are replaced.
Basic LG Appliance Reset Steps
For some error codes, a basic power reset may clear a temporary electronic fault. Reset procedures can vary by model, so check the owner's manual or LG's support information when in doubt.
For Washers, Dryers, and Dishwashers:
Unplug the appliance (or turn off the circuit breaker) for 10 to 15 seconds. Plug it back in and start a new cycle. If the error code was triggered by a momentary glitch, such as a power fluctuation or a sensor hiccup, it should clear.
For Refrigerators:
Unplug the fridge for 60 seconds, then plug it back in. Wait 24 hours for temperatures to stabilize before deciding if the issue is truly resolved. Refrigerators take time to reach their set temperature, so don't panic if it's not ice-cold within an hour.
For Ovens & Ranges:
Press the Clear/Off button first. If the code returns, turn off the circuit breaker for 30 seconds, then turn it back on. Try the original cooking function again.
If the same error code comes back after a reset, the underlying problem hasn't gone away. That's when it's time to follow the specific troubleshooting steps in the tables above, or call a professional.
When to Call a Professional
Some error codes are easy to fix at home. Others point to problems that need a trained technician with the right tools and replacement parts. Here's a quick guide:
Handle It Yourself If:
The code relates to a clogged filter, kinked hose, unbalanced load, closed water valve, or a full lint trap. These are maintenance issues, not mechanical failures. For appropriate non-safety-related codes, a basic reset may be worth trying after checking the model-specific instructions.
Call a Technician If:
The code involves a motor, compressor, control board, heating element, sealed system, or gas component. Also call if you've tried the DIY troubleshooting steps and the code keeps coming back. If an error code repeatedly returns after the recommended troubleshooting steps, the appliance may have an underlying component, wiring, installation, or system problem that requires diagnosis.
