OE — Drain Error#
Common Causes
- Clogged drain pump filter(common) — Coins, hair ties, lint, and small objects accumulate in the drain pump filter, blocking water flow. This is the number one cause of OE errors.
- Kinked or clogged drain hose(occasional) — The drain hose is pushed against the wall, kinked, or has internal buildup restricting flow.
- Faulty drain pump motor(occasional) — The drain pump motor (4681EA2001T) fails after 5-8 years of use, unable to expel water within the 10-minute drain window.
- House drain blockage(rare) — The standpipe or house drain is clogged, preventing water from leaving.
DIY Fix
Warning
Expect 1-2 cups of water when opening the filter. Have towels ready.
- Locate the drain pump filter access panel at the bottom-left of the front panel.
- Place towels and a shallow pan underneath to catch water.
- Turn the filter cap counterclockwise slowly to release water gradually.
- Remove debris from the filter and the pump cavity behind it.
- Check the drain hose for kinks. Disconnect and run water through it to verify flow.
- Ensure the drain hose is inserted 6-8 inches into the standpipe (not too far).
- Reinstall the filter, run a Rinse & Spin cycle to test.
Professional Repair
Estimated Cost
$150-250
Repair Time
30-45 minutes
If cleaning the filter and hose does not resolve OE, the drain pump motor needs replacement. In our Sacramento service calls, OE is the most frequently reported LG washer error, and filter cleaning resolves it about 70% of the time.
UE — Unbalanced Load#
Common Causes
- Unevenly distributed load(common) — A single heavy item or items bunched on one side cause the drum to vibrate excessively during spin.
- Washer not level(occasional) — The washer feet are not properly adjusted, allowing the unit to rock during spin.
- Worn shock absorbers(rare) — On front-loaders, shock absorbers wear out after 5-8 years, reducing the ability to dampen vibration.
DIY Fix
Warning
If UE appears frequently with normal loads, worn shock absorbers ($20-40 each) may need replacement.
- Open the door and redistribute clothing evenly around the drum.
- Add a few towels if washing a single large item to help balance.
- Check that all four leveling feet are firmly on the floor. Adjust and tighten lock nuts.
- Run the spin cycle again.
Professional Repair
Estimated Cost
$150-250
Repair Time
30-45 minutes
Recurring UE with properly balanced loads indicates worn suspension components. Front-loaders have 2-4 shock absorbers; top-loaders have 4 suspension rods.
DE — Door Lock Error#
Common Causes
- Door not fully closed(common) — Clothing caught in the rubber boot gasket prevents the door from latching.
- Faulty door lock assembly(occasional) — The door lock solenoid (EBF49827803) fails to engage or the latch mechanism breaks.
- Wiring issue(rare) — The wire harness between the control board and door lock loosens or corrodes.
DIY Fix
Warning
Do not force the door if the lock mechanism is stuck engaged. Unplug the washer and wait 2-3 minutes for the lock to release.
- Open the door fully and check for clothing or objects caught in the rubber boot gasket.
- Inspect the door strike and latch for visible damage.
- Close the door firmly until you hear a distinct click.
- If the lock is visibly damaged, the door lock assembly (EBF49827803, $30-60) is a replaceable part accessible from inside the door opening.
Professional Repair
Estimated Cost
$120-200
Repair Time
20-30 minutes
Door lock replacement requires peeling back the boot gasket and removing the retaining wire to access the lock. A multimeter test confirms whether the solenoid reads 600-900 ohms.
LG Repair Tools Required
DIY tool investment: $0+ just for basics. Our technician arrives with $15,000+ in professional tools — your diagnostic is free.
IE — Water Inlet Error#
Common Causes
- Water supply valves not open(common) — The hot or cold water valves behind the washer are partially or fully closed.
- Clogged inlet screens(common) — Mesh filters inside the hose connections accumulate sediment and mineral deposits, restricting flow.
- Faulty water inlet valve(occasional) — The inlet valve (5220FR2075L) fails to open when the control board signals it.
- Low water pressure(rare) — Household water pressure below 14.5 PSI prevents adequate fill within the 8-minute window.
DIY Fix
Warning
Have towels ready when disconnecting hoses. Residual water will drain.
- Verify both hot and cold water valves behind the washer are fully open.
- Turn off water supply and disconnect the inlet hoses from the back of the washer.
- Inspect the mesh screens at both the valve and hose ends for sediment.
- Clean screens with an old toothbrush and vinegar.
- Reconnect hoses, turn on water, and run a test cycle.
Professional Repair
Estimated Cost
$130-220
Repair Time
30-45 minutes
If screens are clear and water pressure is adequate, the inlet valve needs replacement. LG requires 14.5-116 PSI. Inlet valve replacement involves removing the top panel and disconnecting two water lines.
LE — Motor Lock Error#
Common Causes
- Overloaded drum(common) — Too many clothes prevent the motor from rotating the drum. LG front-loaders should be filled to about 75% capacity.
- Foreign object jammed(occasional) — Coins, underwire from bras, or small items lodge between the drum and tub, physically blocking rotation.
- Hall sensor failure(occasional) — The rotor position sensor (6501KW2002A) mounted on the stator sends incorrect speed data to the control board.
- Failed stator or rotor(rare) — The direct drive motor components wear out, preventing rotation.
Professional Repair
Estimated Cost
$120-300
Repair Time
30-60 minutes
Turn the drum by hand with the washer off. If it rotates freely but LE persists, the hall sensor ($10-20) is the most likely culprit. If the drum is seized, bearing failure may require $250-450 in professional service. Based on our Bay Area data, hall sensor replacement resolves LE about 60% of the time.
FE — Water Overflow Error#
Common Causes
- Faulty inlet valve stuck open(common) — The water inlet valve fails in the open position, allowing water to flow continuously into the tub.
- Excessive suds(occasional) — Using non-HE detergent or too much detergent creates excessive foam that triggers a false water level reading.
- Pressure switch failure(rare) — The water level sensor sends incorrect readings, causing the board to overfill the tub.
DIY Fix
Warning
If water overflows, turn off water supply valves immediately to prevent flooding.
- Check if you used non-HE detergent or too much detergent. LG front-loaders require HE detergent.
- Run a Tub Clean cycle (or hot cycle with 1 cup white vinegar, no clothes) to clear residual suds.
- If FE appears with correct detergent: unplug the washer. If water continues flowing in, the inlet valve is failed and must be replaced.
Professional Repair
Estimated Cost
$130-220
Repair Time
30-45 minutes
A stuck-open inlet valve is a flooding risk. Professional replacement ensures proper valve seating and verifies the pressure switch is functioning correctly.

tE — Thermistor / Temperature Sensor Error#
Common Causes
- Failed thermistor(common) — The NTC thermistor (6322FR2046G) mounted on the tub reads shorted or open circuit.
- Disconnected wire harness(occasional) — The thermistor connector loosens from washer vibration over time.
Professional Repair
Estimated Cost
$100-170
Repair Time
20-30 minutes
The thermistor should read approximately 40k ohms at 77F. If reading 0 (shorted) or infinite (open), replacement is needed. The part is inexpensive ($10-20) but requires removing the rear panel and testing with a multimeter.
PE — Water Level Sensor Error#
Common Causes
- Clogged pressure hose(common) — The small-diameter rubber hose from the tub to the pressure switch is blocked with debris or detergent residue.
- Failed pressure switch(occasional) — The frequency-based pressure sensor on the control board housing fails to detect water level changes.
Professional Repair
Estimated Cost
$120-200
Repair Time
30-45 minutes
The pressure hose runs from the outer tub to the pressure switch. Blowing gently into the hose should produce a click from the switch. If the hose is clear but PE persists, the pressure switch ($15-30) needs replacement.
CE — Current Error#
Common Causes
- Failed motor stator or rotor(common) — The direct drive motor draws abnormal current due to a shorted winding or damaged component.
- Overloaded circuit(occasional) — Other appliances on the same circuit create voltage drops during the wash cycle.
- Faulty inverter board(occasional) — MOSFET failure on the inverter control board causes incorrect current delivery to the motor.
Professional Repair
Estimated Cost
$200-400
Repair Time
45-60 minutes
CE requires professional diagnosis with a multimeter and oscilloscope to determine if the fault is in the motor, wiring, or control board. Ensure the washer is on a dedicated 20-amp circuit before diagnosis.
DIY Risk: Wrong Diagnosis = Bigger Bill
Replacing the wrong part on your Washer wastes money and time. A wrong diagnosis often turns a $150 repair into a $600+ problem. Our free diagnostic eliminates the guesswork.
PF — Power Failure#
Common Causes
- Power interruption during cycle(common) — A momentary power outage or voltage dip interrupted the wash cycle.
- Loose outlet connection(occasional) — The power cord connection to the wall outlet is not secure, causing intermittent power loss during high-draw spin operations.
DIY Fix
- Press the Start/Pause button to resume the interrupted cycle.
- If PF appears without an actual power outage, check the outlet connection and power cord.
- Ensure the washer is on a dedicated circuit. Check the breaker.

PF is informational. If recurrent without actual outages, have an electrician check the circuit.
CL — Child Lock Active#
Common Causes
- Child lock feature engaged(common) — The child lock was intentionally or accidentally activated, disabling all button presses except Power.
DIY Fix
- Press and hold the Child Lock button (or designated button pair per your manual) for 3-5 seconds.
- CL disappears from the display and buttons resume normal function.
Professional Repair
Estimated Cost
$0
Repair Time
0 minutes
Normal feature operation. No repair needed.
Sud — Excessive Suds Detected#
Common Causes
- Non-HE detergent used(common) — Regular detergent produces far more suds than HE formulations, overwhelming the wash system.
- Too much detergent(common) — Even HE detergent used in excess creates problematic suds levels.
- Residual detergent buildup(occasional) — Accumulated detergent residue in the tub and gasket creates suds even with correct detergent amounts.
DIY Fix
Warning
Never use regular dish soap or hand soap in a washing machine.
- Let the washer pause and wait for suds to dissipate (the washer extends the rinse automatically).
- Switch to HE detergent if you are not already using it.
- Reduce detergent amount. Most people use 2-3x more than needed.
- Run a Tub Clean cycle to clear residual buildup.
Professional Repair
Estimated Cost
$0
Repair Time
0 minutes
Suds is user error, not a mechanical failure. Switching to correct detergent and amount resolves it permanently.
Repair vs Replace: The Math
Most Washer issues are fixable at a fraction of replacement cost. Our free diagnostic tells you exactly what is wrong and gives you an honest quote — no obligation.
AE — Leak Sensor Activated#
Common Causes
- Internal hose leak(common) — The tub-to-pump hose or internal water connections develop a leak, activating the float switch in the base pan.
- Boot gasket tear(occasional) — The rubber door boot gasket develops a tear or crack, allowing water to escape during wash or spin.
- Tub seal failure(rare) — The main tub seal behind the drum leaks, often accompanied by bearing noise.
Professional Repair
Estimated Cost
$150-350
Repair Time
30-60 minutes
AE indicates water in the base pan. Turn off the washer and water supply immediately. Tilt the washer back carefully to drain the base pan. Professional diagnosis is needed to identify the exact leak source.
How to Enter LG Washer Diagnostic Mode#
- Power on the washer with an empty drum.
- Press and hold Spin Speed + Soil Level simultaneously for 3 seconds.
- The washer enters diagnostic mode and cycles through motor, fill, drain, and spin tests.
- Use the LG ThinQ app for Smart Diagnosis on Wi-Fi-enabled models.
- To exit diagnostic mode, press Power or unplug the unit.
LG Smart Diagnosis (phone): call 1-800-243-0000, hold the Temp button, place phone speaker near the Power button area. The washer sends an audio signal for remote diagnosis. Also available via the LG ThinQ app on Wi-Fi models.

Frequently Asked Questions#
How do I reset my LG washer after an error code?
Power off, unplug for 60 seconds, plug back in, and run a short Rinse & Spin cycle. For persistent errors, hold Start/Pause for 5 seconds before powering off. Most codes clear after the underlying issue is resolved and a successful cycle completes.
Why does my LG washer keep showing OE even after I cleaned the filter?
If OE persists after cleaning the drain pump filter, check the drain hose for kinks or internal blockage. Disconnect it and run water through to verify flow. If the hose is clear, the drain pump motor (4681EA2001T) likely needs replacement. Based on our service data, pump replacement resolves persistent OE about 95% of the time.
What does it mean when my LG washer flashes all lights?
Simultaneously flashing lights usually indicate a control board error or power surge damage. Unplug for 5 minutes and retry. If all lights continue flashing, the main control board may need replacement. Inspect the board for visible burn marks or swollen capacitors.
Are LG washer parts covered by warranty?
LG provides a 1-year full parts and labor warranty, a 3-year parts warranty on the control board, and a 10-year limited warranty on the direct drive motor (parts only, no labor). Keep your purchase receipt for warranty claims.
Can I use regular detergent in my LG front-load washer?
No. All LG front-load washers require HE (High Efficiency) detergent. Regular detergent causes excessive suds that trigger SUD/FE errors, reduce cleaning, and can damage the pressure sensor. Use HE-rated detergent and measure carefully.
How do I use LG Smart Diagnosis?
Via phone: call 1-800-243-0000, hold the Temp button while placing your phone speaker near the Power button area. Via app: open LG ThinQ, select your washer, tap Smart Diagnosis. The system decodes error history and provides recommendations.
Why does my LG washer smell bad?
Front-load washers trap moisture in the door gasket. Wipe the gasket after each load, leave the door ajar between uses, and run a Tub Clean cycle monthly with a washer cleaner tablet or 1 cup of white vinegar. This prevents mold and mildew buildup.
How long do LG washers typically last?
Based on our Sacramento and Bay Area repair data, LG washers average 8-12 years. The most common failure points are the drain pump (4-7 years), door lock (5-8 years), shock absorbers (5-8 years), and bearings (7-10 years). Regular maintenance extends lifespan.
Is LG washer LE error serious?
LE can range from a simple overload (reduce clothes and retry) to a failed hall sensor ($90-140 total repair) or seized bearings ($250-450). Try reducing the load first. If LE persists, turn the drum by hand to check for free rotation.
What should I do if my LG washer is leaking?
Check the door boot gasket for tears or debris preventing a seal. Verify the drain hose connection is secure. If leaking from underneath, the AE error typically accompanies this and indicates a hose or tub seal failure requiring professional diagnosis.
