LG Washing Machine Error Code SE2 — What It Means & How to Fix It

What Does This Error Mean?

LG washer error SE2 means the spin speed sensor has detected an issue during the spin cycle. The washer cannot confirm the drum is spinning at the correct speed, so it stops to prevent mechanical damage. This is typically caused by an imbalanced load, a faulty hall sensor, or a problem with the motor.

Common Causes

The laundry load is unevenly distributed in the drum, causing the drum to wobble during spin and confusing the speed sensor
The rotor position hall sensor, which monitors drum speed, has failed or is giving inconsistent readings
A heavy or bulky item such as a duvet is bunching on one side of the drum, creating extreme imbalance
The motor drive system has a fault that is causing inconsistent drum speed during the spin cycle
The main control board is misinterpreting the spin sensor signal due to a software glitch or hardware fault

How to Fix It

Stop the cycle and open the door. Reach into the drum and manually redistribute the laundry — spread items evenly around the drum. Restart the spin cycle.

An uneven load is the most frequent cause of SE2 and spin-related errors. Even a single heavy towel bunched on one side can trigger the error.
Remove any very bulky single items — duvets, large blankets, heavy bath mats — and wash them separately. These items are notorious for balling up on one side during spin.

Large bulky items often wash better in a commercial laundromat machine with a larger drum.
Unplug the washer and wait 2 minutes. Plug it back in and run a spin-only cycle with a small, evenly distributed load. This tests whether the motor and sensor work correctly under controlled conditions.

If a balanced test load spins successfully, the problem is the load distribution rather than a hardware fault.
Check that the washer is sitting level on the floor. Adjust the levelling feet at the bottom corners of the machine until the washer does not rock in any direction.

An unlevel machine creates extra vibration during spin, which can cause the control board to detect a speed inconsistency and trigger SE2.
If SE2 returns consistently even with a small, balanced load on a level floor, the hall sensor or motor needs professional testing. A technician can read diagnostic data from the control board to confirm which component is at fault.

Hall sensor replacement is a moderate-cost repair. Request that the technician run the built-in LG diagnostic cycle to get a precise fault code.

When to Call a Professional

If redistributing the laundry load does not resolve SE2, the hall sensor or motor drive needs professional testing. These components require disassembly of the washer cabinet — contact an LG-certified appliance technician for diagnosis.

Frequently Asked Questions

Why does SE2 mostly happen during the spin cycle?

The spin cycle puts the greatest mechanical stress on the drum and motor. Spin speeds can reach 1,000–1,400 rpm, which amplifies any imbalance or sensor inaccuracy that would go unnoticed at lower wash-cycle speeds. This is why SE2 typically does not appear during washing — only during spin.

My washer shakes violently before SE2 appears. Is that normal?

No. Violent shaking before SE2 is a sign of a severe load imbalance. Stop the cycle, redistribute or remove items, and restart. Repeated severe shaking can loosen internal components over time, so address the imbalance before it causes secondary damage.

Can I prevent SE2 from happening regularly?

Yes. Mix large and small items in each load to create a naturally balanced drum. Avoid washing single heavy items alone — add a few towels to balance the weight. Also keep the washer level and check the feet every six months, as vibration can cause them to shift.
