LG Washer Error Codes: Complete 2026 Guide

Front-Load vs. Top-Load: Which Codes Apply to Your LG Washer

LG sells two major washer types with distinct code sets. Knowing which platform you have changes the diagnosis:

• Front-load (WM series — WM3400, WM4000, WM4500, WM8000, WashTower WKEX): Use codes OE, UE, IE, DE, LE, FE, PE, tE, CE, and dE2. These machines have a door-lock interlock, a pump filter at the bottom front, and LG’s direct-drive motor (no belt). The drum is horizontal.
• Top-load (WT series — WT7300, WT7800, WT7900HV): Use most of the same codes but with differences: UE behavior varies (the machine may add water and agitate to rebalance rather than stopping outright), and there is no dE2 or door-seal gasket. The tE code is less common on top-loaders.
• WashTower (WKEX/WKGX series): These stacked units share the WM front-load code set and may display washer and dryer codes on the shared panel alternately.

How to confirm your model type: The model number is on a label inside the door opening (front-load) or under the lid (top-load). WM = front-load, WT = top-load. If the label is damaged, the ApplianceIQ serial decoder can identify the platform from the model number alone.

Power-Cycle Reset: Start Here Before Anything Else

Every LG washer error-code troubleshooting path starts with the same step. Here is the correct procedure:

1. Press Power to end the current cycle and stop the machine.
2. Unplug the washer from the wall outlet, or trip the circuit breaker to the OFF position.
3. Wait a full 30 seconds to allow the control board capacitors to discharge completely.
4. Restore power, select a fresh wash cycle, and press Start. Watch for the code to reappear.

A code that disappears after a reset and does not return was triggered by a power surge or transient sensor glitch. A code that returns within the first few minutes of a new cycle confirms a real hardware fault — proceed to the relevant section below. For OE (drain) and FE (overflow) codes, do not restart the washer until you have physically resolved the water issue.

OE — Drain Failure (Most Common LG Washer Code)

OE stands for Output Error — the machine attempted to drain the tub but water was still detected by the pressure sensor after the allotted pump time (typically 3–5 minutes). The washer stops with water still in the drum.

OE is the single most common LG washer error code. Field service data consistently shows that 60–70% of OE calls resolve with a filter cleaning alone — a free, 20-minute fix that requires no parts.

Step 1: Clean the Drain Pump Filter

The drain pump filter traps lint, coins, hair ties, and small garments before they reach the pump impeller. On LG front-load washers, the filter is behind a small rectangular access door at the bottom front of the machine. On top-load models the filter is not user-accessible (it is inside the pump housing).

1. Place a shallow tray or stack of towels directly under the access panel.
2. Open the panel and pull out the small black drain tube. Uncap it to drain residual water slowly — typically 1–3 liters.
3. Once the water stops, turn the large filter cap counterclockwise and pull it straight out.
4. Rinse the filter under running water. Remove any debris caught on the fins. Check the filter housing cavity for objects that may have bypassed the filter.
5. Reinsert the filter, tighten clockwise firmly (hand-tight plus a quarter turn), and replace the access panel.
6. Run a short cycle to test.

LG recommends cleaning the drain pump filter every 2 months or whenever OE appears.

Step 2: Check the Drain Hose

If the filter is clean and OE returns, inspect the drain hose that runs from the back of the machine to the standpipe or utility sink:

• Kinks: Pull the washer away from the wall. A sharp bend near the rear connector is common after the machine has been pushed back into position.
• Standpipe height: LG requires the drain hose end to be 18–96 inches above the floor. A standpipe that is too low creates a siphon effect — water drains and immediately re-enters the tub, triggering OE.
• Drain hose clog: Disconnect the drain hose from the standpipe and blow through it. A resistance near the machine-end connection indicates a clog inside the hose.

Step 3: Drain Pump Motor Failure

If the filter is clean, the hose is clear, and OE persists, the drain pump motor has likely failed. Signs: you can hear the pump attempting to run but making a humming or grinding noise, or no sound at all when drain should be active.

UE / uE — Unbalanced Load

UE (displayed as UE or uE depending on the model) means the drum detected uneven weight distribution during the spin acceleration ramp. The machine reduces spin speed and attempts to rebalance the load automatically — typically two or three times — before displaying UE and stopping.

UE is almost always a user-correctable issue, not a hardware failure:

• Single heavy item: Washing one large item (a comforter, a heavy denim jacket, a bath mat) without smaller items to act as counterweights is the most common trigger. Add two or three similar-weight towels to balance the load.
• Tightly packed drum: On front-loaders, laundry can pack into one quadrant of the drum. Open the door and shake items loose before restarting.
• Delicate or wool cycles: These cycles spin slowly by design; some machines show UE transiently at low speeds even with a balanced load. If clothes come out damp but no fault persists, this is normal behavior for the cycle type.

When UE points to a hardware issue: If UE appears consistently with normally loaded cycles across multiple wash loads, the suspension rods (front-load) or balance ring (top-load) may be worn. On LG front-loaders, all four suspension rods should be replaced together if one is worn. Suspension rod kits cost $25–$60.

IE / 1E — Water Intake Error

IE (sometimes displayed as 1E on older LG models with 7-segment displays that render I as 1) means the washer did not detect the expected water level within the fill timeout — typically 8 minutes for a normal cycle start.

Diagnosis sequence for IE:

1. Check supply valves: Both the hot and cold valves (behind the machine) must be fully open — turned counterclockwise until they stop. A half-open valve is enough to trigger IE on cold-water cycles, since many modern LG washers mix cold and hot even for “Cold” washes.
2. Inspect hoses for kinks: The same push-back-against-wall problem that causes OE can restrict the inlet hoses too.
3. Clean the inlet mesh screens: Turn off both supply valves. Disconnect the hoses from the back of the washer. Look into the valve ports on the machine — you will see small mesh screens. Rinse them under running water or use a soft brush. These screens clog with sediment over time, especially in hard-water areas.
4. Water pressure too low: LG washers require a minimum water pressure of 14.5 PSI (1 bar) to fill correctly. If your home water pressure is low, the fill valve may not open fully.
5. Failed inlet valve: If all of the above check out and IE persists, the dual-solenoid inlet valve has likely failed. Replacement cost: $25–$50 for the part, about 20 minutes to swap.

DE / dE — Door Error

DE (or dE) means the washer’s control board cannot confirm that the door is securely closed and locked. This is a safety interlock — LG front-load washers will not start or continue a cycle without a confirmed door lock signal.

• Laundry in the door gasket: The single most common cause on front-loaders. A small sock or shirt sleeve can prevent the door from closing fully. Open the door, check the rubber bellows seal all the way around, and restart.
• Worn door latch: The latch hook on the door can deform after years of use. If the door closes with a loose feel rather than a firm click, the latch needs replacement. Cost: $15–$25.
• Failed door lock assembly (interlock): The interlock contains both the mechanical latch receiver and the electrical switches that signal the control board. When the switch fails, the door closes and latches mechanically but the board never receives the “door locked” signal — DE appears immediately at cycle start. Replacement door lock assemblies cost $20–$40 and take about 15 minutes to install.
• dE2: Some LG models distinguish between dE (door not closed) and dE2 (door closed but lock switch not engaging). If you see dE2 specifically, the interlock switch is the target, not the latch hook.

LE — Motor Lock Error

LE means the motor controller detected that the motor was not rotating when commanded, or that it was drawing current high enough to trigger an overcurrent shutdown. On LG direct-drive front-loaders (which use a motor that attaches directly to the drum with no belt), LE is the washer equivalent of a seized engine.

LE diagnosis steps:

1. Power cycle first: Unplug for 30 seconds. Restart with a lighter load. Overloading is a common LE trigger on heavily packed loads, and a reset often clears a thermal LE.
2. Check for a jammed object: Open the door and reach into the space between the drum and the door gasket seal. Small items — underwires, coins, bone buttons — can wedge between the drum and the tub wall, preventing the drum from spinning freely. Try rotating the drum by hand to feel for resistance.
3. Rotor position sensor (hall sensor): LG direct-drive motors use a hall-effect sensor to report rotor position to the control board. When this sensor fails, the board cannot confirm motor rotation and throws LE. The sensor is a small board bolted to the stator; replacement sensors cost $10–$25. Accessing it requires removing the rear panel and unbolting the rotor (a large permanent magnet ring) — a 45–60 minute DIY job.
4. Stator or rotor damage: If the hall sensor is fine and LE persists, the stator windings or rotor magnets may have failed. Professional diagnosis is recommended at this point.

FE, PE, tE — Overflow, Pressure Sensor, and Temperature Codes

FE — Overfill / Overflow Error

FE means the tub is overfilling — water continued entering past the target level and the pressure sensor is reading above the safe threshold. The washer cuts off the wash motor and attempts an emergency drain.

Immediate action for FE: Turn off both water supply valves behind the machine. Do not restart the washer until you have identified and fixed the fill source. If water is still in the drum, select a Drain+Spin cycle (select No Spin, then press Start) to remove it.

The cause is almost always a stuck-open water inlet valve — a solenoid that is not closing when commanded. Replacement cost: $25–$60. The valve must be replaced before the machine can be safely used again.

PE — Water Level Pressure Sensor Error

PE means the pressure sensor (also called the water level sensor or pressure switch) is not reading within the expected range. The sensor is a small transducer connected to the tub by a thin rubber hose — it measures air pressure in the hose, which corresponds to the water depth in the tub.

Common PE causes:

• The sensor hose has slipped off its connection at the tub or the sensor body. Reconnecting it often clears PE with no parts needed.
• The sensor hose is kinked, pinched, or has water trapped inside it. Disconnect the hose at the sensor end and blow through it — you should feel air resistance. If the hose is blocked, clear the obstruction.
• The pressure sensor itself has failed. Replacement sensors cost $15–$35.

tE — Thermistor / Temperature Error

tE on an LG washer means the water temperature sensor (thermistor) is reading outside the expected operating range, or the circuit is open. Unlike on LG dryers, washer tE codes are relatively uncommon — most LG washers heat water only for sanitize cycles or steam options.

tE is most common on: WM models with Steam (WM4500HBA, WM8000H series) and on cycles that specify a target temperature (Allergiene, Steam Sanitary). On cold-water-only cycles, the thermistor is not actively queried and tE will not appear.

The thermistor on LG front-load washers is typically mounted on the heater assembly at the bottom rear of the tub. Power-cycle first. If tE returns, check the thermistor harness connector for corrosion, then test resistance (should read 10–50 kΩ at room temperature). Replacement thermistors cost $15–$30.

CE and PF — Current Error and Power Failure

CE — Current Error (Motor Overcurrent)

CE means the motor controller detected a current spike in the drive circuit — the motor tried to draw more power than the inverter board allows. CE often appears together with LE or after an LE, since a stalled motor that keeps trying to start will produce overcurrent. The diagnosis path for CE overlaps with LE: power cycle, check for jammed drum, check motor hall sensor.

CE can also indicate a failing inverter board (the motor control board behind the rear panel). If CE appears on a machine with a freely spinning drum and no jammed objects, the inverter board is the most likely target. Inverter boards cost $80–$180 and are one of the more expensive LG washer repairs — confirm the diagnosis carefully before ordering.

PF — Power Failure

PF is not a hardware fault — it means the washer lost power mid-cycle (power outage, surge, or an unplugged cord). When power is restored, PF appears to let you know the cycle was interrupted. Press Start to resume the interrupted cycle from roughly where it stopped, or press Power to cancel and start a new cycle. No repair needed.

CL and Other Informational Codes

Not every code on an LG washer is an error. These notifications indicate machine state, not a fault:

DIY vs. Call a Tech: Decision Guide

Most LG washer error codes resolve with a cleaning, an adjustment, or a $25–$50 part. Here is where to draw the line:

Repair vs. Replace: The Math for LG Washers

LG washers have an average lifespan of 10–14 years. LG direct-drive front-loaders tend toward the higher end of that range when maintained; top-loaders with agitators typically land in the 10–12 year window. Use the 50% rule as your threshold: if repair cost exceeds 50% of a comparable new washer’s price (currently $700–$1,400 for mid-range LG models), replacement usually makes more economic sense.

• OE filter cleaning on any age machine: Always fix. Free, takes 20 minutes. Even a 14-year-old machine is worth this.
• OE drain pump replacement on a unit under 8 years old: Repair. $40–$70 is well under threshold.
• Door lock assembly on any age unit: Repair. $20–$40 is a trivial cost regardless of age.
• LE hall sensor on a unit under 10 years old: Repair. $10–$25 part, 45-minute job.
• CE requiring inverter board replacement on a unit under 7 years old: Repair if it is the first major failure. At $80–$180, this is still under the 50% threshold.
• CE + LE + inverter board on a unit over 10 years old: Evaluate carefully. If two major components have failed in the same 18-month window, the machine is likely at end of economic life — replacement is usually more sensible.
• Stator or rotor failure on a unit over 8 years old: Get a repair estimate first. Stator replacements run $150–$300 installed. For a machine over 10 years old without warranty coverage, replacement is often the smarter move.

Before booking a service call, run your LG washer’s model and serial number through ApplianceIQ. It returns the exact manufacture date (critical for determining whether the drum or motor is still under LG’s limited warranty), active recall status, and estimated remaining lifespan — so you enter the repair conversation with full context. Free tier includes 25 lookups/month. You can also decode the manufacture date manually using our LG serial number decoder guide.
