What Does Error HE Mean?

The LG Dishwasher HE error code indicates a malfunction in the heating system, preventing the water from reaching the proper temperature needed for effective cleaning and drying. This can lead to poor performance, such as inadequate drying or cleaning during cycles. Common causes include a faulty heating element, a defective temperature sensor, or issues with the control board. If the HE error persists after attempting basic resets, further diagnosis is necessary.

Common Symptoms:

  • HE displayed on control panel mid‑cycle or at start
  • Dishwasher fails to heat water adequately
  • Poor cleaning and drying performance due to lack of heat
  • Error persists even after restarting machine

Possible Causes

  • Faulty heating element (medium)
  • Defective temperature sensor / thermistor (medium)
  • Control board or wiring issues (medium)

How to Fix Error HE

DIY Fix Basic checks and reset

  1. Power off the dishwasher — unplug or switch off circuit breaker.
  2. Wait ~1–5 minutes and restore power to attempt a reset.
  3. Ensure hot water supply to dishwasher is adequate (run kitchen hot tap before cycle).
  4. Check that filters and spray arms are clean to support proper heat distribution.

Technician Only Diagnose and repair heating system

  1. Verify continuity of the heating element with a multimeter; replace if out of spec.
  2. Test the thermistor resistance at expected temperature range; replace if faulty.
  3. Inspect wiring harness and connectors for damage and secure connections.
  4. Check the control board for proper voltage to heater circuit and replace if defective.

Parts needed: Heating element, Thermistor / temperature sensor, Control board (if needed), Wiring harness/connectors

🛑 When to Call a Pro:
  • If error persists after reset and basic checks
  • If internal electrical diagnostics/findings are beyond basic user capability (e.g., measuring voltages)
  • If heater or sensor replacements do not resolve the issue
