LG washers use a consistent set of two-letter error codes across front-load and top-load models. The five most frequent codes are: OE (drain error — clean the pump filter first), UE (unbalanced load — redistribute laundry), IE (water inlet — check supply valves and inlet screens), LE (motor locking — power cycle, check for foreign objects), and dE (door not latched — check gasket and latch). Start every diagnosis with a 10-minute power cycle. Codes that return after a reset indicate a real component fault — use the full table and section guides below to identify which one.
Front-Load vs. Top-Load: Which Codes Apply to Your Machine
LG uses the same core error-code vocabulary across front-load and top-load washers, but a handful of codes are model-type-specific. Front-load washers (the horizontal-drum machines with a porthole door) use the full set of door codes (dE, dE1, dE2) because they have a door latch and interlock. Top-load washers (the vertical-drum machines with a lid) use a lid switch instead of a door latch; lid faults may not produce a visible code on older top-load models.
The LE1 variant of the motor locking error is more commonly documented on top-load models. The tCL Tub Clean reminder appears on both types. If you see a code on your display that isn't in this guide, it may be model-specific — consult your unit's owner's manual or contact LG support at 1-800-243-0000.
How to identify your LG model type: The model number is on a sticker inside the door opening on front-load machines (on the rim around the drum), and on the back panel or inside the lid frame on top-load machines. If your sticker is faded or missing, the ApplianceIQ serial decoder can identify the appliance type from the model number.
First Step for Every Code: The Power-Cycle Reset
Before diagnosing any component, attempt a full power-cycle reset. LG's control boards can generate transient fault codes from power-line noise, brief supply interruptions, or communication glitches between the board and individual components. These transient faults resolve themselves after a full board reset — no part replacement needed.
- Press the Power button to end the current cycle and power off the washer.
- Unplug the power cord from the wall outlet.
- Wait a full 10 minutes. This fully discharges the control board's capacitors and resets all firmware state.
- Plug back in, power on, and run a short cycle (Quick Wash with a small load).
- If the same code returns within the cycle, a physical component has failed. Proceed to the relevant section below.
Important: Do not attempt five or six power cycles hoping the code clears. If OE, LE, or tE returns after one proper reset, the underlying component has failed and further resets only delay the diagnosis.
OE — Drain Error: The Most Common LG Washer Code
OE is by far the most frequently reported LG washer error code. It means the machine attempted to drain the drum but the water level did not drop within the expected time window — typically around 10 minutes on most models. The washer pauses the cycle with standing water in the drum.
How to clean the LG drain pump filter (resolves OE in most cases):
- Open the small access panel at the lower front of the washer. It either pops open with a pry tool or is secured by two Phillips screws.
- You'll see a round filter cap (often black or gray) and a small drain hose. Pull the drain hose, unclip its stopper, and let residual water drain into a shallow tray or onto towels — there may be 1–2 liters.
- Once drained, turn the filter cap counterclockwise and pull it out.
- Remove all debris — lint, coins, hairpins, buttons, small socks. Rinse the filter under running water. Use a small brush to clean the housing cavity.
- Reinsert the filter, turn clockwise until snug. Push the drain hose back and clip its stopper. Close the access panel.
- Run a spin/drain-only cycle to confirm OE is cleared.
If OE returns after cleaning the filter: Check the drain hose at the back of the machine for kinks or sharp bends. The drain hose exit point should not be higher than 96 inches from the floor (LG's maximum standpipe height). If the hose and filter are clear, the drain pump motor itself has failed — the pump assembly typically costs $25–$45 and is a moderate DIY replacement (requires removing the front panel on most front-load models).
| Symptom | Likely cause | Fix | DIY difficulty |
|---|---|---|---|
| OE first time, water in drum | Clogged pump filter | Clean filter (see steps above) | Very easy — 10 minutes |
| OE returns after cleaning filter | Kinked or too-high drain hose | Straighten hose; lower standpipe if >96″ | Easy |
| OE with no debris in filter | Pump motor failure | Replace drain pump assembly (~$25–$45) | Moderate — front panel removal |
| OE with error immediately at spin start | Control board not triggering pump | Tech recommended — board diagnosis | Tech required |
IE — Water Inlet Error
IE means the washer attempted to fill the drum with water but did not reach the required water level within the allotted time. LG's fill timeout is typically 8–10 minutes; if the water level sensor hasn't registered adequate fill by then, the machine stops and shows IE.
Diagnosis order:
- Check the supply valves. Both the hot and cold supply valves behind the washer must be fully open. It sounds obvious, but a partially closed valve — often left that way during installation or after maintenance — is a common IE cause.
- Clean the inlet screen filters. The water inlet valve has small mesh screens inside each hose port that catch sediment and mineral scale. Disconnect the hoses, use needle-nose pliers to pull the screens out, and rinse them under running water. In hard-water areas, screens can clog completely within 2–4 years.
- Check water pressure. LG washers require a minimum water supply pressure of approximately 14.5–20 PSI. Very old homes, homes at the end of a long supply run, or homes with well pumps can fall below this threshold, causing intermittent IE codes. Test with a gauge at the hose bib.
- Inspect the inlet valve. If supply pressure is adequate and screens are clean, the water inlet valve's solenoid has likely failed and is not opening when energized. Replacement inlet valves cost $25–$55 depending on model.
UE / uE — Unbalanced Load
UE (or uE on some display styles) is the most benign common LG washer code — in the majority of cases it is not a component failure at all, just physics. LG front-load washers use a high-speed spin (up to 1,200–1,400 RPM on most models) that requires the load to be balanced around the drum. When the machine's out-of-balance sensor detects excessive vibration, it stops and displays UE to prevent drum damage.
When UE points to a real failure: If UE appears consistently with a well-distributed load, or if the machine shakes violently before displaying UE, the shock absorbers or suspension rods have likely worn out. On front-load LG washers, there are typically two shock absorbers at the bottom of the tub; on top-load models, 3–4 suspension rods hold the inner tub. Shock absorbers cost $20–$50 for the set and are a moderate DIY replacement. Worn suspension rods are similar in cost and difficulty.
Also check: Ensure the washer is on a level surface (use a spirit level on top of the machine and adjust the leveling feet as needed) and that the shipping bolts were removed during installation. Shipping bolts left in the machine are a surprisingly common cause of severe vibration and repeated UE on newer LG washers.
LE / LE1 — Motor Locking Error
LE indicates the washer's direct-drive motor could not rotate, or the hall sensor monitoring rotor position detected an out-of-range reading. LG washers use a BLDC (brushless DC) direct-drive motor mounted directly on the back of the drum — there is no belt. This design is highly reliable but when the motor does fail, the stator winding or the hall sensor (position sensor built into the stator) is usually the culprit.
Diagnosis steps:
- Power cycle. Unplug for 10 minutes. Transient LE codes from momentary current spikes clear with a full reset. Restart with a small load (or empty).
- Reduce the load. LE can appear if the drum is overloaded — more torque required to spin than the motor can generate under those conditions. Remove half the load and retry.
- Check for foreign objects. A coin, bra wire, or small fastener caught between the drum and the back gasket (on front-load machines) can physically block the drum from turning. Rotate the drum by hand — it should turn freely. Any resistance or grinding indicates an obstruction or a bearing failure.
- If LE persists on an empty, freely-rotating drum: The stator assembly or hall sensor has failed. The stator is the ring-shaped component behind the rear panel that surrounds the rotor. A replacement stator kit (stator + hall sensor + rotor, sold as a set for most LG models) costs $50–$120. It requires removing the rear panel and the rotor — a moderate DIY job.
LE1 (top-load models): Same root cause — motor locking error. More commonly appears on top-load LG washers with the pulsator-style drum. The diagnosis and fix are the same; the stator kit part number will differ by model.
dE, dE1, dE2 — Door Errors
LG uses three related door codes on front-load washers, each pointing to a different layer of the door-locking system:
| Code | Meaning | Common cause | Fix |
|---|---|---|---|
| dE | Door detected open or not fully latched | Laundry caught in door gasket; door not pushed firmly shut | Check gasket; close door firmly; retry |
| dE1 | Door physically open (not closed) | Same as dE; or door hinge sagging on heavy door | Confirm door is closed; check hinge alignment |
| dE2 | Door lock mechanism failure | Door latch actuator or micro-switch failed | Replace door latch assembly (~$15–$35) |
Diagnosing dE vs. dE2: If pressing the door closed firmly makes the dE code clear and the cycle proceeds, the problem is a loose gasket flap or a slightly misaligned door — not a failed component. If the door is fully closed and latched but dE or dE2 persists, the door lock actuator has failed. This is a quick DIY repair: the door latch assembly snaps out of the door frame (or is held by two screws on some models) and the replacement plugs directly in. Part cost is typically $15–$35 from LG parts or aftermarket suppliers.
Safety note: LG front-load washers will not allow a cycle to start if the door lock signal is not confirmed. A chronic dE2 that is bypassed rather than repaired can leave the door unlocked mid-cycle — a flood risk if the door opens under water pressure.
tE, FE, PE — Thermistor, Overflow, and Pressure Sensor Codes
| Code | System | Meaning | First action |
|---|---|---|---|
| tE | Heating | Thermistor (water temperature sensor) fault — reading out of range | Power cycle; if persistent, test thermistor resistance; replace if open/short (~$15–$25) |
| FE | Water supply | Overflow error — water level exceeded safe maximum | Immediately close supply valves; unplug; drain drum; replace inlet valve (stuck open) |
| PE | Water level | Pressure sensor / air dome hose fault — machine can't read water level accurately | Check air dome hose connection (small clear hose from tub to pressure sensor); clear clogs; replace sensor if hose is intact (~$15–$30) |
tE in detail: LG washers with a heating element (most front-load models sold in the US since ~2014 include a heater for sanitize and allergen cycles) use an NTC thermistor to monitor water temperature. When the thermistor reads outside the expected range — typically below -40°F or above 284°F (sensor open-circuit or short-circuit) — the control board stops the cycle and shows tE. Test the thermistor by unplugging the washer, disconnecting the thermistor harness, and measuring resistance with a multimeter at room temperature. A healthy LG NTC thermistor reads approximately 10,000–15,000 ohms at 68°F (20°C). Open circuit (infinite ohms) or short circuit (near zero ohms) confirms failure.
FE requires immediate action. An overflow condition means water is continuously flowing into the drum because the inlet valve is stuck open — either mechanically or because the solenoid coil has failed in the energized (open) position. Close both supply valves immediately, unplug the washer, and drain the drum before attempting any diagnosis. Do not restart the machine until the inlet valve has been replaced.
PE and the air dome hose: The pressure sensor measures water level by reading air pressure in a sealed hose connected to the drum tub — called the air dome hose or pressure hose. It is a small clear or black hose about 3–4mm in diameter. Lint and detergent residue can partially clog it, causing inaccurate level readings and PE codes even though the sensor itself is fine. Disconnect the hose from the pressure sensor, blow through it to check for blockage, and clean with warm water if clogged.
CE, AE, PF, tCL, CL, nF — Less Common Codes
| Code | Meaning | Action required |
|---|---|---|
| CE | Motor current error — motor drawing too much or too little current | Power cycle first. If persistent, motor or control board fault. Tech recommended. |
| AE | Leak / flooding sensor triggered — water detected in the base pan | Unplug immediately. Check door boot seal, hose connections, and pump for leaks. Fix leak before restarting. |
| PF | Power failure — cycle interrupted by loss of power | Not a component fault. Power was interrupted mid-cycle. Restart the cycle. |
| tCL | Tub Clean reminder — maintenance notification, not an error | Run Tub Clean cycle (empty drum + LG Tub Clean tablet or 1/3 cup liquid chlorine bleach). Reminder clears after cycle completes. |
| CL | Child Lock active — not an error | Press and hold the Child Lock button combination for 3 seconds to deactivate. Consult your manual for the exact key combination. |
| nF | Wi-Fi / network connection lost (ThinQ models only) — not an error | Reconnect to the LG ThinQ app. The washer operates normally without a Wi-Fi connection. |
AE deserves special attention. Unlike most LG washer codes which allow the machine to continue functioning, AE means the flood protection sensor in the base tray has been triggered by actual water. Do not attempt to restart the washer. Tip the machine forward slightly to drain water from the base, then systematically check the door boot seal (a common failure point after 5–8 years on front-loaders), all hose connections, and the pump housing. A cracked door boot seal replacement costs $25–$60 and is a DIY-possible repair, but requires removing the front panel and door assembly.
tCL is the most misunderstood LG washer notification. Owners frequently call for service thinking the machine is broken, but tCL is simply a scheduled maintenance reminder triggered after a set number of wash cycles (typically 30). LG's front-load washers accumulate detergent residue and biofilm in the drum, door gasket, and dispenser — running Tub Clean monthly with an appropriate cleaner extends the machine's life and prevents odor.

Before ordering parts, confirm that your LG washer is not still under warranty. LG's standard limited warranty on washers is 1 year parts and labor, with a 10-year warranty on the motor (the direct-drive BLDC motor specifically). An LE code on a washer under 10 years old may be a covered motor warranty claim — call LG support at 1-800-243-0000 with your model and serial number before purchasing a stator kit. To quickly decode the manufacture date from your serial number, run it through the LG serial number decoder.
Repair vs. Replace Math for LG Washers
LG front-load washers have a median lifespan of approximately 10–14 years; LG top-load washers trend toward the higher end of that range due to their simpler mechanical design. The 50% rule applies: if repair cost exceeds 50% of an equivalent new unit's price, replacement is usually the better financial decision.
Applied to the most common LG error codes:
- OE (pump failure) on a unit under 10 years old: Repair without hesitation. $25–$45 part on a machine worth $600–$1,100 is a trivial expense.
- LE (stator) on a unit 5–10 years old: Repair. $50–$120 DIY for a stator kit is well under threshold, and LG's motor may still be under the 10-year warranty. Even at full technician labor ($150–$300 installed), repair is clearly the right call for a mid-life unit.
- CE (motor + control board) on a unit over 10 years old: Evaluate carefully. If both the motor and control board have failed simultaneously, total repair cost can approach $400–$600 — pushing past the 50% threshold for a unit worth $600–$800 as a replacement. Consider the machine's overall condition and history.
- AE (severe leak from drum bearing failure) on a unit over 10 years old: Bearing replacement on a front-load LG is a complex, labor-intensive job ($300–$500 installed) and may signal end-of-life for the tub seal and bearing as a system. On a machine over 12 years old, replacement is almost always the right choice.
