Quick Answer
A Samsung HE error usually indicates a heating problem in your appliance. On Samsung dishwashers, washing machines, and dryers, the HE error commonly appears when the unit cannot heat water or air properly. This can be caused by a faulty heating element, damaged thermostat, wiring problems, or a malfunctioning control board. In many cases, cleaning components, resetting the appliance, or replacing a failed heating part will resolve the issue.
What Does a Samsung HE Error Mean?
The Samsung HE error stands for Heating Error. The appliance has detected that water or air is not reaching the proper temperature during operation.
Common causes include:
- Failed heating element
- Faulty temperature sensor
- Damaged thermostat
- Loose or damaged wiring
- Control board problems
- Power interruptions
Before replacing expensive parts, work through the troubleshooting steps below.
Tools and Materials Needed
- Phillips screwdriver
- Multimeter
- Flashlight
- Work gloves
- Owner’s manual
How to Fix a Samsung HE Error
Step 1: Reset the Appliance

Electronic glitches can sometimes trigger a false HE error.
- Turn the appliance off.
- Unplug it from the wall outlet.
- Wait 5 minutes.
- Plug it back in.
- Start a new cycle.
If the error returns, continue with the next step.

Step 2: Check for Proper Power Supply

Heating components require full voltage to operate correctly.
- Verify the outlet is working properly.
- Check the circuit breaker.
- Inspect the power cord for damage.
- Avoid using extension cords.
Low voltage can prevent heating elements from reaching operating temperature.
Step 3: Inspect the Heating Element

A failed heating element is one of the most common causes of a Samsung HE error.
- Disconnect power.
- Access the heating element according to your model.
- Look for visible damage, burns, or breaks.
- Test continuity using a multimeter.
If the heating element fails the continuity test, replace it.
Step 4: Test the Temperature Sensor

The temperature sensor monitors water or air temperature.
- Disconnect power.
- Locate the thermistor or temperature sensor.
- Inspect wiring connections.
- Test resistance according to the manufacturer’s specifications.
A faulty sensor may send incorrect readings and trigger the HE error.
Step 5: Inspect Wiring Connections

Loose or damaged wiring can interrupt power to heating components.
- Disconnect power.
- Inspect wire harnesses leading to the heater.
- Look for burnt connectors.
- Repair or replace damaged wiring.
Even a partially disconnected wire can cause intermittent heating failures.

Step 6: Check the High-Limit Thermostat

Many Samsung appliances include a safety thermostat that shuts off heating if temperatures become excessive.
- Disconnect power.
- Locate the high-limit thermostat.
- Test continuity with a multimeter.
- Replace the thermostat if it is open.
A failed thermostat will prevent the appliance from heating properly.
Step 7: Inspect the Main Control Board

If all heating components test properly, the control board may not be sending power to the heater.
- Disconnect power.
- Remove the access panel.
- Inspect the control board for burnt areas.
- Look for damaged relays or loose connectors.
Because control boards can be expensive, verify all other components first.

When to Call a Professional
Contact a qualified appliance technician if:
- The HE error returns after troubleshooting
- Electrical testing is required
- The control board appears damaged
- Wiring repairs exceed your comfort level
- The appliance is still under warranty
How to Prevent Samsung HE Errors
Prevent future heating problems by:
- Cleaning filters regularly
- Avoiding overloaded cycles
- Using the correct detergent
- Inspecting power connections periodically
- Addressing minor heating issues promptly
- Performing routine appliance maintenance
Regular maintenance helps heating components last longer and operate more efficiently.
Frequently Asked Questions
Is a Samsung HE error serious?
The error typically indicates a heating problem. While the appliance may still power on, it often cannot complete cycles correctly until the issue is resolved.
Can I continue using my appliance with an HE error?
It is not recommended. Heating problems can affect cleaning, drying, or washing performance and may lead to additional component damage.
Will unplugging the appliance clear the Samsung HE error?
A reset may clear a temporary fault, but the error will usually return if an actual heating component has failed.
How much does it cost to repair a Samsung HE error?
Costs vary depending on the failed component. Heating elements and thermostats are typically less expensive than replacing a control board.
What component most commonly causes a Samsung HE error?
The heating element is one of the most common causes, followed by faulty temperature sensors and wiring problems.
Final Thoughts
A Samsung HE error usually points to a heating system problem involving the heating element, temperature sensor, thermostat, wiring, or control board. Start with a simple reset and power check before moving on to component testing. In many cases, replacing a failed heating element or thermostat will restore normal operation and eliminate the error code.
