What SE means

SE is a general sensor error on LG front-load washers with an alphanumeric display, including the washer half of a WashTower and the WashCombo. The control read something it could not accept from one of its sensors and stopped the cycle. The owner sees SE on the display, and the code does not say which sensor was involved. The code does not state which sensor or circuit raised it.

Common causes of SE

Sensor reading outside the expected range
Brief hiccup that may not repeat
Sensor wiring or connector

✓ One safe check you can try

1. Unplug the washer for 10 seconds. 2. Plug it back in. 3. Restart the cycle. 4. Write down the cycle and any other message on the display. 5. Check that the power cord is pushed in firmly. 6. Close the door fully and make sure the load is not caught in the door seal.

! Why to stop there

Because SE does not name a sensor, a repeat leaves several circuits possible.
We narrow it down by testing the sensing circuits in turn, then give a written price before work.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

SESE questions

Which sensor does SE refer to?

The code only says sensor error. It does not name one, so the first job for a technician is finding out which circuit is involved. Several sensors feed the control, so the first task is working out which one the washer is complaining about.

Can a restart clear SE?

It can if it was a one-time reading problem. Unplug for 10 seconds, plug in, and see whether it returns. If it clears, keep an eye on it. If it returns, a second reset will not help.

What do you do if SE comes back?

We check the sensing circuits and wiring, explain what we find, and quote before replacing anything. We test the likely circuits, tell you what we find, and give a written price before any part is replaced.
