LG Washer Error Codes: Complete Troubleshooting Guide for Every Code

LG washing machines are known for their reliability and innovative features, but like all appliances, they occasionally display error codes when something goes wrong. Understanding these codes helps you determine whether you're facing a quick fix or need professional repair.

This guide covers error codes for LG front-load and top-load washers—including the popular WM series and newer ThinQ smart models that we service throughout Metro Atlanta.

How LG Washer Error Codes Work

When your LG washer encounters a problem, it displays a two-letter code on the control panel. The washer typically stops operation and may beep to alert you.

First step for any error: Press the Power button to turn off the washer, unplug it for 30 seconds, then plug it back in and restart. Many temporary errors clear with this simple reset.

If the error returns, proceed with the specific troubleshooting steps below.

OE — Drain Error (Most Common)

What it means: The washer can't drain water within the expected time (typically 10 minutes).

This is the most common LG error code we encounter in Metro Atlanta service calls.

Troubleshooting Steps

1. Check the drain filter (front-load models)

• Locate the small access door at the front bottom of the washer
• Place towels and a shallow pan underneath—water will flow out
• Turn the filter cap slowly and remove
• Clear any debris, coins, hair, or small items
• Replace the filter and cap securely

2. Inspect the drain hose

• Ensure it's not kinked or crushed behind the washer
• Check that it's not inserted too far into the standpipe (6-8 inches maximum)
• Verify the standpipe isn't clogged

3. Check for a siphon problem

• The drain hose should form a high loop before entering the drain
• Without this loop, water can siphon out during fill cycles

4. Test the drain pump

• Listen for the pump running during drain cycles
• A humming sound without water movement indicates a failing pump

When to Call a Professional

If cleaning the filter and checking the hose doesn't resolve the issue, the drain pump likely needs replacement. This is a common repair that typically takes about an hour.

UE or UB — Unbalanced Load

What it means: The washer can't spin because the load is unbalanced.

Why This Happens

• Single heavy item (comforter, blanket, jeans)
• Load shifted to one side of the drum
• Too few items in the drum
• Washer not level

Troubleshooting Steps

1. Redistribute the load

• Open the door and spread items evenly around the drum
• Separate tangled items
• Add similar items to balance a single heavy piece

2. Check washer level

• Place a level on top of the washer front-to-back and side-to-side
• Adjust the leveling feet until the washer is perfectly level
• Ensure the locking nuts are tight

3. Avoid problematic loads

• Wash heavy items with similar-weight items
• Don't wash a single towel or blanket alone
• Don't overload or underload

When to Call a Professional

If the UE error persists with properly distributed loads and a level washer, the shock absorbers or suspension rods may be worn. These components absorb vibration during spinning and wear out over time, especially in machines that have handled many unbalanced loads.

LE or LE1 — Motor Locked Error

What it means: The motor can't turn the drum.

This error requires careful diagnosis because multiple issues can cause it.

Possible Causes

Overloaded drum: Too many items create excessive resistance.

Rotor position sensor failure: The sensor that tells the control board where the drum is positioned has failed.

Hall sensor failure: Similar to the rotor sensor, this monitors motor operation.

Motor wiring issue: Loose or damaged connections.

Control board problem: The main board can't communicate with the motor.

Troubleshooting Steps

1. Reduce the load size and restart
2. Unplug for 30 seconds to reset
3. Check if the drum rotates freely by hand (unplug first)
4. Look for foreign objects jamming between the drum and tub

When to Call a Professional

LE errors usually indicate a sensor or motor issue that requires professional testing. The rotor position sensor and hall sensor are common failures that we repair regularly.

dE, dE1, dE2 — Door Error

What it means: The washer detects that the door isn't closed or locked properly.

Troubleshooting Steps

1. Close the door firmly

• Push until you hear a click
• Don't slam—this can damage the latch

2. Check for obstructions

• Look for clothing caught in the door seal
• Ensure nothing is blocking the latch mechanism

3. Inspect the door latch

• Check for visible damage
• Clean any debris around the latch

4. Examine the door strike

• The part the latch hooks onto may be misaligned
• Look for wear or damage

When to Call a Professional

If the door closes properly but the error persists, the door lock assembly or door switch has failed. These components wear out over time and require replacement.

FE — Water Overflow Error

What it means: The washer is detecting too much water.

Possible Causes

Faulty water inlet valve: Stuck open, allowing water to enter continuously.

Pressure switch failure: Can't accurately measure water level.

Control board issue: Sending incorrect signals to the inlet valve.

Troubleshooting Steps

1. Turn off the washer and observe if water continues entering
2. Turn off the water supply valves behind the washer
3. If water was still entering with the washer off, the inlet valve is stuck open
4. Check that the pressure hose (thin tube from tub to control) isn't kinked or disconnected

When to Call a Professional

FE errors usually indicate a water inlet valve problem that needs replacement. Don't continue using the washer—overfilling can cause water damage.

tE — Temperature Sensor Error

What it means: The water temperature sensor (thermistor) is malfunctioning.

Troubleshooting Steps

1. Unplug the washer for 30 seconds and restart
2. Try a cycle that doesn't require heated water (cold wash)
3. Check your water heater is functioning if hot water seems unavailable

When to Call a Professional

Persistent tE errors indicate a failed thermistor or wiring issue. The sensor is inexpensive, but accessing it requires disassembly.

PE — Water Level Sensor Error

What it means: The pressure switch can't determine the water level.

Troubleshooting Steps

1. Unplug and reset the washer
2. Check if the washer fills with water at all
3. Listen for a humming or buzzing sound during fill

When to Call a Professional

PE errors indicate a failed pressure switch or disconnected/damaged pressure hose. This requires inspection of internal components.

PF — Power Failure

What it means: The washer lost power during a cycle.

What to Do

1. Press Power to turn the washer back on
2. Press Start to resume the cycle or select a new cycle
3. Check your home's circuit breaker
4. Consider a surge protector if power interruptions are common

This isn't an appliance fault—it's simply alerting you that power was lost.

CL — Child Lock Activated

What it means: The child lock feature is on, not an error.

What to Do

Press and hold the Child Lock button (or button combination) for 3-5 seconds. Check your owner's manual for the specific method for your model.

tcL — Tub Clean Reminder

What it means: It's time to run a tub cleaning cycle.

What to Do

Run the Tub Clean cycle (without clothes) using a washing machine cleaner or white vinegar. This maintains hygiene and prevents odors.

dHE — Duct Heater Error (Combo Units)

What it means: On LG washer-dryer combos, the dryer heating system has a problem.

When to Call a Professional

This requires diagnosis of the heating element, thermistor, or control board. Don't use the drying function until repaired.

AE — Auto Sensing Error

What it means: Communication failure between the main control board and the sub-board.

Troubleshooting Steps

1. Unplug for 10 minutes (longer than typical reset)
2. Plug back in and attempt a cycle

When to Call a Professional

AE errors usually indicate a control board problem. This is a more complex repair that requires professional diagnosis.

IE — Water Inlet Error

What it means: The washer isn't filling with water properly.

Troubleshooting Steps

1. Check water supply

• Verify both hot and cold faucets are fully open
• Ensure water supply to the house is on

2. Inspect inlet screens

• Turn off water and disconnect hoses from the washer
• Check the small mesh screens where hoses connect—they clog with sediment
• Clean screens carefully

3. Check water pressure

• Fill a bucket from the supply—should fill a gallon in 30 seconds
• Low pressure can prevent proper filling

When to Call a Professional

If water supply is fine and screens are clean, the water inlet valve may be failing. This is a straightforward repair.

Sud or Sd — Excessive Suds

What it means: Too much detergent or the wrong type was used.

What to Do

1. Let the washer run—it will extend the rinse cycle to clear suds
2. Use HE (High Efficiency) detergent only
3. Use the recommended amount (often less than you think)
4. Run an extra rinse cycle if needed

This is a user-related issue, not a malfunction. Excessive suds can eventually damage components if it happens repeatedly.

Troubleshooting Tips for All LG Error Codes

Document the Error

• Write down the exact code
• Note when it occurs (during fill, wash, spin, or drain)
• Note if it's consistent or intermittent

Check LG Smart Diagnosis (ThinQ Models)

Newer LG washers have Smart Diagnosis. Download the LG ThinQ app and hold your phone to the washer when prompted—it can diagnose many issues automatically.

Review Warranty Status

LG washing machines typically include:

• 1-year full warranty
• 2-year parts warranty on the control board
• 10-year warranty on the direct drive motor

Check your warranty status before paying for repairs.

When to Repair vs. Replace Your LG Washer

Repair makes sense when:

• The washer is under 7 years old
• This is the first major repair
• Repair cost is under $400

Consider replacement when:

• The washer is over 10 years old
• Multiple components are failing
• Repair cost exceeds $500

LG washers typically last 10-14 years with proper maintenance.
