Samsung Washing Machine Error Code HE1: What It Means and How to Fix It
The Samsung washing machine error code HE1 means the washer's heating element is overheating. Unlike the general HE or HC heater codes (which mean the heater is not producing heat), HE1 specifically means the water temperature has risen above safe operating limits. The washer stops the cycle as a safety precaution. Unplug the washer immediately and do not attempt to run another heated cycle. This error requires professional repair in nearly all cases.
What Does Samsung Washing Machine Error Code HE1 Mean?
The Samsung washing machine error code HE1 is a heater overheating error that indicates the water temperature inside the drum has exceeded the safe operating range. Samsung washers with built-in heaters monitor temperature through a thermistor. When the thermistor detects that water temperature is climbing beyond what the selected cycle requires (and the heater is not shutting off), the washer triggers HE1 and stops the cycle to prevent potential burns, damage to clothing, or harm to internal components.
HE1 is a more specific and more serious variant than the general HE or HC codes. Where HE/HC mean "the heater is not working," HE1 means "the heater is working too much." The heater relay may be stuck in the on position, the thermistor may be reading incorrectly (telling the board the water is cold when it is actually hot), or the control board is not cutting power to the heater at the right time.
Because an overheating heater is a safety concern, HE1 should be treated as urgent. Do not attempt to run warm or hot cycles until a technician has diagnosed and repaired the underlying cause. Cold-water cycles that do not activate the heater can still be used safely while you wait for service.
Why Samsung Washing Machine Shows Error Code HE1
How to Fix Samsung Washing Machine Error Code HE1 (Step-by-Step)
Unplug the washer immediately
Disconnect the washer from the power outlet right away. Because HE1 indicates overheating, cutting power stops the heating element from continuing to run.
Wait at least 15 minutes for the washer to cool
Leave the washer unplugged and the door closed for at least 15 minutes. The water inside the drum may be much hotter than normal. Do not open the door until the machine has had time to cool down.
Plug the washer back in and check the display
After the cooling period, restore power. If the HE1 code reappears immediately on the display without starting a cycle, the fault is persistent and the washer needs a technician.
Run a cold-water cycle only
If the display cleared after the reset, select a cold rinse or cold wash cycle. Cold-water settings do not activate the heating element, so they are safe to run. If the cold cycle completes normally, the overheating issue is confirmed to be in the heating circuit and needs professional diagnosis.
Schedule a technician before using heated cycles
Even if the cold cycle works, do not use warm, hot, sanitize, or steam settings until a technician has inspected the heater relay, thermistor, and control board. The overheating fault will return on any cycle that activates the heater.
If the code returns after these steps, the issue is internal and needs a technician. Overheating errors involve electrical components (heater relay, thermistor, wiring harness) that are not safe to access or repair without professional training.
When to Stop and Call a Technician
HE1 is one of the few Samsung washer errors that should always lead to a service call. Contact a Samsung appliance repair technician if:
- The HE1 code appears at all, even once (overheating is a safety issue, not a nuisance code)
- You notice steam escaping from the washer door or detergent drawer
- The door glass or top panel feels unusually hot during or after a wash cycle
- You detect a burning or electrical smell near the washer
- The code returns after a power reset, even without running a heated cycle
How Promix Repairs Samsung Washing Machine HE1 Errors
When a Promix Appliance Repair technician arrives for an HE1 overheating error, the first step is testing the heater relay on the control board to determine if it is stuck in the closed (on) position. A failed relay keeps the heater energized continuously. The technician also tests the thermistor for accurate resistance readings at room temperature and compares them to the manufacturer's expected values. A thermistor that reads low will cause the board to keep heating past the safe threshold.
If the relay and thermistor both test normally, the technician inspects the wiring harness for shorts or damage that could keep the heater circuit energized. Promix technicians carry common Samsung washer and dryer repair parts, including thermistors and control boards, for same-day completion when the part is in stock. Every repair includes a warranty on parts and labor, backed by 10+ years of experience.
A service call fee applies and is credited toward the repair if you choose to proceed. Call Promix Appliance Repair at (781) 666-9565 to schedule same-day service.

Frequently Asked Questions
Can I keep using my Samsung washing machine with error code HE1?
You can run cold-water cycles only. Do not use any cycle that activates the heater (warm, hot, sanitize, or steam) until a technician has repaired the overheating fault. Cold rinse and cold wash settings do not engage the heating element and are safe to use.
Will resetting my Samsung washing machine clear error code HE1?
Unplugging the washer for 15 minutes will clear the HE1 code from the display. However, because HE1 indicates the heater is overheating (a safety concern), a reset alone does not mean the problem is fixed. If the code appeared even once, schedule a technician to inspect the heater relay, thermistor, and wiring before running heated cycles again.
How long does it take to fix Samsung error code HE1?
The power reset takes about 15 minutes. Professional repair typically takes 45 to 90 minutes depending on whether the issue is the thermistor, the heater relay, or the control board. Promix Appliance Repair carries common Samsung parts for same-day completion when available.
Is Samsung error code HE1 covered under warranty?
If your Samsung washer is within the manufacturer's warranty period (typically one year for parts and labor), a repair for a defective heater relay or thermistor may be covered. Component failure due to normal wear over many years of use is generally not covered. Check your warranty documentation or contact Samsung to confirm.
What is the difference between Samsung error codes HE1 and HE?
HE (and its newer equivalent HC) means the heater is not producing heat. HE1 means the heater is overheating, which is the opposite problem and a more serious safety concern. HE means the washer cannot heat water. HE1 means the washer is heating water too much. Both require professional repair, but HE1 should be treated as more urgent.
Is Samsung error code HE1 dangerous?
An overheating washer heater poses a real risk. Excessively hot water can damage clothing, warp plastic components inside the drum, and in extreme cases cause scalding if the door is opened while the water is superheated. Samsung washers shut down when HE1 is detected precisely to prevent these risks. Do not override the error or attempt to bypass the safety lockout.
