What Does Error HE Mean?

The Samsung Dishwasher HE error indicates a heating system malfunction, where the dishwasher detects abnormal water temperature behavior, often due to issues with the heating element or temperature sensor. This error can cause the dishwasher to stop mid-cycle or fail to heat water adequately. If the error persists, it's essential to diagnose the faulty components to restore proper operation.

Common Symptoms:

  • Dishwasher displays HE error and may stop mid‑cycle
  • Dishwasher fails to heat water to target temperature
  • Temperature diagnostics detect out‑of‑range values during operation

Possible Causes

  • Abnormal water temperature detected by dishwasher’s internal diagnostics (high)
  • Faulty temperature sensor (thermistor) (medium)
  • Faulty heating element or heater circuit problem (medium)
  • Wiring or main control board failure affecting heater control (low)
