What HE (Heater Error) Means
HE indicates a temporary or genuine fault with the washer's water heater, per LG's front-load washer Help Library article.
Common Causes of HE (Heater Error)
- Temporary heater control glitch
- Heater element itself has failed
- Heater wiring or relay fault
🔧 One Safe Check You Can Try
Unplug the washer, wait about 10 seconds, reconnect, and restart the wash cycle; this clears a temporary heater glitch if that's what caused it.
⚠ Why You Shouldn't Go Further Than That
- If HE persists after a reset, the heater element or its control relay needs a technician's diagnosis and replacement - it's not a part accessible without opening the cabinet.
- Continuing to select cycles that call for heated water (sanitary, allergen) with a failed heater won't achieve the sanitizing temperature those cycles are meant to reach, even if the cycle otherwise completes.
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.
