Samsung Washer Error Code HE1: Causes, Fixes, and Troubleshooting

A Samsung washing machine displaying the HE1 error code is reporting a problem with its water heating system. Samsung identifies HE1 on many washer models as a water heater malfunction.

The washer may stop the cycle because it cannot heat the water correctly or detects an abnormal condition in the heating system. The exact troubleshooting procedure can vary by model, so your washer's manual should be used as the final reference.

What Does HE1 Mean on a Samsung Washer?

Samsung washer error code HE1 generally indicates that the water heater is not functioning correctly.

Samsung's official support information lists HE1 as a water heater not functioning error. Samsung also groups HE1 with heater-related faults on some models.

Possible causes include:

  • Failed heating element

  • Faulty temperature sensor

  • Loose heater connection

  • Damaged wiring

  • Heater relay problem

  • Control board fault

  • Abnormal water-heating condition

Signs You May Notice With HE1

The washer may display HE1 along with one or more of these symptoms:

  • Water does not heat properly

  • The wash cycle stops unexpectedly

  • The washer takes unusually long to complete a cycle

  • HE1 appears repeatedly

  • Clothes are not being washed at the expected temperature

These symptoms can help indicate that the heating system needs attention.

Try a Power Reset First

Samsung recommends power-cycling the washer for HE1/HE2 heater errors on applicable washer-dryer models.

To reset the washer:

  1. Turn the washing machine off.

  2. Disconnect it from the power supply.

  3. Leave it switched off for about five minutes.

  4. Reconnect the power.

  5. Turn the washer on.

  6. Start a suitable wash cycle.

If HE1 disappears and does not return, the problem may have been temporary.

If the code comes back, the heating system should be checked.

Check the Water Supply Connection

For some Samsung models, water-temperature errors can be related to incorrect water connections. Samsung advises checking that the washer's water hose is connected correctly, particularly ensuring that the cold-water hose is connected to the cold supply.

Check that:

  • The water hose is connected securely.

  • The correct inlet is being used.

  • The water supply is turned on.

  • The hose is not kinked.

However, if the washer specifically displays HE1, the heater itself may still require inspection.

What Parts Can Cause HE1?

If resetting the washer does not clear the error, several components may need to be tested.

Heating Element

The heating element is responsible for heating the water during temperature-controlled wash programs. A failed element can prevent the washer from reaching the required temperature.

Temperature Sensor

The temperature sensor monitors the water temperature. If it provides an incorrect reading, the control system may detect a heating fault.

Heater Wiring

Loose, damaged, or disconnected wiring can prevent the heating element from operating correctly.

Heater Relay

On some models, a relay controls power to the heating system. A defective relay can prevent the heater from receiving power.

Main Control Board

If the heater and associated components are functioning correctly, the control board may need to be investigated.

Samsung service information for heater-related faults can include the heater, heater relay, wiring harness, heater terminals, thermistor, and main PCB depending on the appliance and model.

Should You Keep Using the Washer With HE1?

If HE1 repeatedly appears, it is better to stop using the washer until the problem has been diagnosed.

A heating-system fault involves electrical components, so avoid opening the washer or attempting to test internal components unless you have the appropriate technical knowledge.

If you notice burning smells, smoke, sparks, damaged wiring, or repeated circuit-breaker trips, disconnect the appliance from power and arrange professional service.

When to Call Samsung Service

Professional repair is recommended if:

  • HE1 returns after a power reset

  • The water remains cold during heated wash cycles

  • The washer repeatedly stops during operation

  • The heating element may be faulty

  • You suspect damaged wiring

  • The temperature sensor may be malfunctioning

  • The washer shows additional error codes

Samsung's support guidance recommends contacting Samsung Service when HE1 persists after the basic troubleshooting steps.

Can You Fix HE1 Yourself?

There are a few safe checks you can perform yourself, including:

  • Power-cycling the washer

  • Checking the water connections

  • Checking for obvious external problems

  • Confirming that the correct water supply is connected

However, testing or replacing the heating element, temperature sensor, wiring, relay, or control board requires opening the appliance and should generally be left to a qualified technician.

Frequently Asked Questions

What does HE1 mean on a Samsung washing machine?

HE1 usually indicates a water-heater problem. Samsung's support documentation describes HE1 as a water heater that is not functioning.

How do I clear HE1 on my Samsung washer?

Turn the washer off, disconnect it from power for approximately five minutes, reconnect it, and restart the machine. If HE1 returns, professional diagnosis may be required.

Why is my Samsung washer not heating water?

A faulty heating element, temperature sensor, wiring connection, heater relay, or control component can potentially prevent the washer from heating water correctly.

Is HE1 the same as HE2?

No. On Samsung washers that use these codes, HE1 is associated with the water heater, while HE2 can relate to the dryer heater on washer-dryer models.

Can I use my Samsung washer when HE1 appears?

If HE1 repeatedly appears, it is better to stop using the appliance until the heating problem has been diagnosed. Do not bypass or disable the washer's safety systems.

Final Thoughts

The Samsung washer HE1 error code generally points to a water-heating problem. Start with a five-minute power reset and check that the washer's water connections are correct.

If HE1 returns, the heating element, temperature sensor, wiring, relay, or control system may need to be tested. Since these components involve electrical systems, professional repair is the safest option when basic troubleshooting does not resolve the error.
