Samsung Washing Machine HE error code

The washer detected a water-heating fault - the water heated abnormally or the heater circuit failed. The cycle stops because temperature cannot be controlled safely.

Also shown as: HE, HE1, HC

Last updated: October 6, 2026

Quick answer: Samsung washing machine error code HE: water heater error. The most common cause is failed heating element (open or shorted). Try this first — power-cycle the washer. If that does not clear it, try a cold-water cycle. If the code persists, call a qualified technician.

What causes the HE error?

  • Failed heating element (open or shorted)
  • Failed thermistor misreading water temperature
  • Heater relay stuck on the control board
  • Loose or damaged heater wiring
  • Heavy scale on the heater from hard water

How to fix Samsung HE — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-cycle the washer
    Unplug the washer or flip its breaker for 2 to 3 minutes, then try a cycle. This resets the heater control after a transient trip.
  2. Try a cold-water cycle
    Run a cold wash to see whether the machine operates normally without heating. If cold cycles work and hot ones throw HE, the heater circuit is confirmed faulty.
  3. Reduce the load and retry
    An extreme overload can strain the heater circuit on some models. Try a smaller load once - if HE persists regardless, it is a parts fault.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • HE returns after a reset
  • The heater needs multimeter testing or replacement
  • The thermistor or heater relay is faulty
  • Heater wiring is damaged

Frequently asked questions

Can I just wash everything cold to avoid HE?

As a temporary workaround, yes - cold cycles do not use the heater. But get the heater fixed, since hot washes will keep failing.

Is HE dangerous?

The shutdown is the safety system working. But a heater fault can involve a stuck relay overheating water, so do not ignore a returning HE.

Does descaling help with HE?

It can help prevent it - heavy scale insulates the heater and stresses it. But once HE is persistent, the heater or sensor usually needs replacement.
