Quick answer

On a Samsung dishwasher, HE is a heater error: the control detects an incorrect temperature. Samsung suggests emptying the dishwasher, adding detergent and running a normal cycle. If HE returns, contact its service centre.

Safety first

Stop and check this first

  • The heater runs on mains voltage and sits under the tub: do not remove the base or kick plate to check it. That is work for the service technician.

Safe checks you can perform

  • Test cycle with the unit empty
  • How the dishes come out
  • Model and code for the service

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Heater and temperature sensor measurement
  • Do not attempt this professional task: Test cycle with heating

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Heater and temperature sensor measurement

    What they doWith the unit disconnected, the technician measures the heater, its circuit and the temperature sensor against Samsung specification.

    They must show youthe measured values against specification.

    In writingwhat was measured, the result, the replaced part with its reference and the reason.

  2. Test cycle with heating

    What they doAfter the repair, the technician runs a normal cycle and checks that the water heats and HE does not return.

    They must show youa full cycle with no code.

    In writingthe test, the result and the date.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Test cycle with the unit empty

    No special tools

    Who:
    you.
    How:
    take all dishes out, add detergent and run a normal cycle, as Samsung says.
    Result that matters:
    whether the cycle finishes without HE.
    If it finishes with no code:
    it was a one-off glitch; watch the next loads.
    If HE returns:
    Samsung asks you to contact the service centre; do not keep repeating cycles.
    Evidence to keep:
    note the date, the programme and whether and when HE appeared.

  2. How the dishes come out

    No special tools

    Who:
    you, by watching.
    How:
    notice whether dishes come out cold or with residue after the washes where HE appears.
    Result that matters:
    a fact that helps the technician separate a heater that does not heat from a wrong reading.
    If they come out cold or dirty:
    tell the technician with the date of each cycle.
    If they come out hot and clean despite the code:
    mention it too; the technician will cross-check it when measuring.
    Evidence to keep:
    a note for each cycle with HE.

  3. Model and code for the service

    No special tools

    Who:
    you.
    How:
    photograph the panel showing HE and the model and serial label.
    Result that matters:
    the service knows which heater and sensor your unit has.
    If the unit is under warranty:
    say so when you request service.
    If you cannot find the label:
    the manual says where it is.
    Evidence to keep:
    dated photos.

What it means

Samsung calls HE a heater error. Samsung Canada describes it as incorrect temperature detection and Samsung Latin America groups it with HC as a high temperature heating check. The control compares the water temperature with what it expects during heating. The only home step Samsung gives is a test: empty unit, detergent and a normal cycle. The code does not say whether the heater, the sensor or the control failed: if it persists, the service technician diagnoses it.

Symptoms and causes

Probable causes · in order

  • One-off cycle glitchPossible

    Told apart with the test Samsung suggests: if the normal cycle with the unit empty and detergent finishes without HE, there is no fault to chase for now.

  • Heater not heating as expectedPossible

    Samsung calls HE a heater error. Only measuring the heater and its circuit against specification confirms it, never the code alone.

  • Incorrect temperature readingPossible

    Samsung Canada describes HE as incorrect temperature detection, so the sensor is also in play. The technician separates it from the heater by measuring both.
