What HE usually means
HE usually belongs to a heating or water-temperature condition on supported LG dishwasher models.
Codes can vary by exact LG dishwasher model number, production year, and regional design. Use this as first-pass guidance, then confirm the model-specific manual or manufacturer support page before opening panels or replacing parts.
First checks
Record when HE appears, confirm the cycle selected, and avoid repeated heated retries.
Heating warnings can involve temperature sensing, control readings, water conditions, or heater circuits.
- Note cycle and time remaining.
- Check for recent power interruption.
- Avoid high-temperature repeat tests.
- Use service for heater circuit checks.
When to stop
Stop if HE returns after one safe retry, if the breaker trips, or if there is burning smell.
Keep the full model number, exact HE display text, cycle name, and timing ready before contacting LG support or a qualified technician.
Model numbers affected
Commonly searched model families include built-in dishwashers, front-control dishwashers, top-control dishwashers, and compact dishwashers.
