What SE (Sensor Error) Means
SE indicates a general sensor error, per LG's front-load washer Help Library article, without naming which specific sensor beyond the family the tE and PE codes already cover.
Common Causes of SE (Sensor Error)
- Temporary sensor-read glitch
- A control-board sensor (unspecified by LG beyond the general SE label) has failed
🔧 One Safe Check You Can Try
Unplug the washer, wait about 10 seconds, reconnect, and restart the wash cycle to see if the fault was a temporary glitch.
⚠ Why You Shouldn't Go Further Than That
- Because LG doesn't name a specific sensor for SE the way it does for tE (temperature) or PE (water level), diagnosing which one has actually failed needs a technician's tools rather than a guess.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
