What Does Error Code HE Mean on a Samsung Dishwasher?

Heater error — water not heating.

The heating element is not bringing the water up to temperature, so dishes aren't sanitized and the heated-dry stage leaves them wet. A burned-out element or a failed NTC sensor that misreports water temperature are the most common causes; the heater relay is the next suspect.

What Causes Error Code HE?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Heating element burned out 50% of cases
  2. 2
    NTC temperature sensor failure 30% of cases
  3. 3
    Control board heater relay failure 15% of cases
  4. 4
    Loose wiring at the element terminals 5% of cases

How to Fix Samsung Dishwasher Error Code HE

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Test the heating element

    With power off, measure across the element terminals — about 15–30 ohms is normal; no continuity means it's open.

    ⚠️ Cut power at the breaker before testing.
  2. 2

    Test the NTC sensor

    Measure the temperature sensor at room temperature — roughly 6k–7k ohms is normal; far off means replace it.

    🔩 NTC sensor ($15–$40)
  3. 3

    Replace the failed component

    Install the element or sensor that tested bad and run a full cycle to confirm the water now heats.

How to Reset Error Code HE

Cut power at the breaker for 5 minutes after replacing the element or sensor, then run a full normal cycle and check that the water heats and the dishes come out dry to confirm HE has cleared.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

Call a technician if both the element and the NTC sensor test within spec but HE persists, since the control board's heater relay has then failed and requires board-level diagnosis and replacement.

Average professional repair cost for this issue: $200–$400

Frequently Asked Questions

Can I keep using my Samsung Dishwasher when error HE appears? +
It is not advisable. The dishwasher may still power on, but running it while HE is active can worsen the heating fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes HE on a Samsung Dishwasher? +
Across reported Samsung dishwasher repairs, the most frequent is heating element burned out (50% of cases), nTC temperature sensor failure (30%), then control board heater relay failure (15%). Check them in that order before replacing any parts.
HE keeps coming back after a reset — what should I check next? +
A reset only clears the stored HE fault; if it returns, the heating problem is still present. Move on to the physical checks — test the heating element, then test the NTC sensor — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Samsung Dishwasher error HE? +
A DIY repair typically runs $15–$90 in parts, versus $200–$400 for a professional service call, so handling it yourself saves around $185. Expect the work to take roughly 30–60 minutes.
