What tE4 (Steam Thermistor Error) Means
tE4 indicates a Steam Thermistor Error, per LG's Styler Help Library error-code list - a fault with the sensor monitoring the temperature of the Styler's steam-generating system.
Common Causes of tE4 (Steam Thermistor Error)

🔧 One Safe Check You Can Try
The unit will require a repair service, per LG's documentation.
⚠ Why You Shouldn't Go Further Than That
- The steam-generating components are inside the Styler's water-heating system, not a homeowner-accessible part, and a faulted steam-temperature sensor means the unit can't safely confirm the steam cycle is operating within its intended range.
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.
