LG Washer Error Codes: Complete Guide (with Fixes)

Every common LG washing machine error code explained — OE, IE, UE, LE, DE, FE, tE and more. What they mean, likely causes, and DIY fixes that actually work.

LG washers are reliable — until they flash a code at you. Good news: LG codes are standardized across most models, so this guide covers the machine you’re staring at.

The most common LG washer error codes

OE — Drain error (most common)

Water isn’t draining. Fix first: clean the drain pump filter — it’s behind the small door at the bottom-front of the machine (have a towel and shallow pan ready; water will spill). Also check the drain hose for kinks and clear the drain pump of coins, buttons, and lint. If the pump runs but nothing drains, the pump impeller or the pump itself is failing.

IE — Water supply error

No water coming in. Check the water valves are open, hoses aren’t kinked, and the inlet filters (at the back of the machine where hoses attach) aren’t clogged. Hard-water scale and debris in the filters cause this constantly.

UE — Unbalanced load

Load is too heavy or uneven to spin. Redistribute the clothes, keep loads balanced, and make sure the washer is level (adjust the feet — a rocker causes this). If it persists on every load, the suspension/shock absorbers may be worn.

LE — Motor lock error

The motor is locked or drawing too much current. First: unplug for 5 minutes and retry. If it returns, check for something stuck between the drum and tub (bra wires, coins in the bellows), then the motor/control board. A seized drain pump can also trigger this — check the pump filter first.

DE / dE1 / dE2 — Door error

Door won’t lock or unlock. Check the door is fully closed with nothing caught in the seal, then inspect the door lock assembly — a broken latch is a common, cheap fix. dE2 usually means the lock won’t release.

FE — Overflow error

Water level too high. The water inlet valve is likely stuck open — turn off the water supply immediately, and replace the valve assembly.

tE — Thermistor error

Temperature sensor fault. The thermistor sits near the heater; check the connector, then test resistance with a multimeter (it should change with temperature).

PE — Pressure sensor error

The water level sensor (pressure switch) isn’t working. Check the pressure hose for blockages and the sensor connections.

PF — Power failure

The cycle was interrupted by a power loss. This one’s usually harmless — just restart the cycle.

How to read LG codes on newer models

Newer LG washers (2020+) may show codes like OE followed by a number (e.g., OE1, OE2) — the number narrows down the cause (OE1 = drain filter clog, OE2 = drain pump). Same for IE1/IE2 (IE1 = valve closed, IE2 = filter clog) and UE1/UE2. The fix path is the same as above.

The 3-step fix for any LG code

Power cycle: unplug 5 minutes — clears transient codes (PF, LE lockups).
Clean the obvious: pump filter, inlet filters, drain hose, leveling.
Test the part: the code tells you which system; test with a multimeter before buying anything.

Parts & tools you’ll need

LG drain pump filter replacement (if cracked)
Multimeter for continuity tests
Inlet hose filters (replace if corroded)
Leveling tool / wrench for feet

FAQ

Q: LG washer shows OE but the pump runs — what now? A: If the filter is clean and the hose is clear, test the pump’s continuity. If it reads open, replace the pump. Also check the drain hose height — the end must not be more than ~96 inches above the floor.

Q: What does LE mean on an LG washer? A: Motor lock error. Unplug for 5 minutes first; then check for stuck objects between drum and tub, and the drain pump (a seized pump can trigger LE).

Q: Can I reset my LG washer error code? A: Yes — unplug for 5 minutes or press and hold the Power button. Codes that return immediately indicate a real fault.

Codes vary slightly by model and year. Confirm with your model’s manual before ordering parts. When in doubt, a licensed appliance tech is worth the call.
