The **HE** display on a Samsung dishwasher points to **high-temperature / heater error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **HE**. Search normalization stores it as **HE** while preserving the characters a homeowner actually sees.

Quick answer
High-temperature / heater error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so HE may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **HE** display on a Samsung dishwasher points to **high-temperature / heater error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **HE**. Search normalization stores it as **HE** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
While HE is active, heating may be weak, absent, excessive, or stop unexpectedly.
HE can be accompanied by this pattern: the appliance can pause when the control detects an unsafe or implausible temperature condition.
The HE display becomes more meaningful if drying, washing, cooking, or defrost performance may change depending on the appliance.
A symptom that fits HE is that hE appears during the dishwasher function associated with high-temperature / heater error.
On affected Samsung dishwasher models, the cycle may stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
As an external check for HE, confirm the selected cycle or cooking mode is supposed to use heat.
For HE, start by doing this: check airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
The next non-invasive check is to allow the appliance to cool before any owner-accessible inspection.
Before requesting service for HE, do not open energized high-voltage or heating sections.
With HE recorded, record the code before resetting.
With HE recorded, check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. If resolving HE would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. If HE keeps returning, record the stage at which it reappears so the technician can test the high-temperature / heater error path instead of replacing parts by guesswork.

You can try the one reset Samsung documents for the model, but **HE** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Do not keep operating the appliance through a hazardous symptom just to see whether **HE** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
No. **HE** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dishwasher HE** separate from same-looking codes used by other Samsung appliance families.
