Samsung Washer Error Code HE1

Samsung Washer Error Code HE1: What It Means and How It Impacts You

The HE1 error on Samsung washers typically indicates a heating-related fault in models that use an internal heater for steam, sanitize, or hot-water wash cycles. This code appears when the washer detects that the heater is not reaching the expected temperature or the temperature sensor isn’t reporting correctly. Common reasons include a failed heating element, a faulty thermistor/temperature sensor, damaged wiring or connectors, or a malfunctioning control board that no longer drives the heater properly. For users, an HE1 error can cause longer cycles, laundry not being sanitized or cleaned effectively, persistent odors from low-temperature washes, and increased energy use as cycles retry or extend. In some cases, heating faults carry safety risks such as electrical shorts, burning smells, or in extreme scenarios fire risk — so treat this code seriously and power down the appliance before inspecting internal components.

Common Causes

• Failed heating element (open circuit or shorted)
• Defective thermistor/temperature sensor (improper resistance readings)
• Damaged or corroded wiring harness and connectors to heater or sensor
• Main control board or relay/triac failure that cannot drive the heater
• High-limit thermostat or safety cut-out activated
• Blocked steam/vent passages or clogged filters (in combo washer-dryers)
• Firmware or control software glitch (less common)
• Overloaded drum or incorrect cycle selection causing repeated heating attempts

Troubleshooting Steps

1. Power-cycle the washer: unplug or switch off the breaker for 1–2 minutes, then restore power to clear transient errors and see if HE1 returns.
2. Check if the code appears only on certain cycles: run a cold wash and a hot/steam cycle to confirm if the heater is involved.
3. Inspect for odors, burns or visible damage: if you smell burning or see scorching near the control panel or back, disconnect power immediately and call a technician.
4. Access service/download mode (if your model supports it) to view error history and confirm heater/thermistor fault codes. Refer to your model’s service manual for the exact procedure.
5. Visually inspect wiring and connectors to the heater and temperature sensor for loose pins, corrosion, or melting. Ensure power is disconnected first.
6. Test the heater element with a multimeter for continuity; an open circuit usually means the element needs replacement. Also test for unexpected shorts to chassis ground.
7. Measure the thermistor/temperature sensor resistance at room temperature and compare to the service manual chart; if out of range, replace the sensor.
8. If heater and sensor check out, test the output from the main control board (relay or triac) for proper switching — do this only if you are experienced with live testing, otherwise hire a pro.
9. Inspect and clean any lint traps or steam passages on combo models; restricted airflow can cause control anomalies related to heating.
10. After repairs or part replacements, clear the error and run a short hot cycle to confirm the fault is resolved.
11. If multiple components fail tests or if the control board appears burnt or damaged, replace the board or contact Samsung-authorized service.

Maintenance / Prevention Tips

• Run a monthly tub-clean or maintenance cycle to prevent residue build-up that can affect heating performance.
• Avoid overloading the drum; excess load can strain systems and cause repeated heating attempts.
• Use correct detergent and recommended amounts to reduce residue and scale on internal parts.
• Periodically check and clean screens, lint filters, and steam vents (on combo units).
• Keep the washer well-ventilated and avoid tight spaces that trap heat near the back panel.
• Inspect the power cord and plug for damage; ensure the washer has a proper grounded outlet and correct voltage.
• Schedule annual professional maintenance if you use hot or sanitizing cycles frequently.
• Address odd smells or sparks immediately — don’t keep using the washer when you notice unusual signs.
• Check hoses and connections for leaks that could corrode electrical connections over time.
• Do not use adapters or extension cords that can cause voltage drop to the heater.
• Update washer firmware if Samsung provides updates for your model (may fix control logic issues).
• Replace worn or damaged wiring harnesses promptly instead of patching them temporarily.
• Use recommended service parts rather than aftermarket substitutes for the heater and sensors.
• Keep the area behind the washer free of lint and debris that could cause overheating.
• Follow manufacturer load and cycle recommendations for sanitize and steam options.

Frequently Asked Questions (FAQs)

Conclusion / Safety Notice

Because HE1 is related to heating and electrical components, exercise caution. Always disconnect power at the breaker or unplug the washer before opening access panels. If you detect burning smells, visible damage, or if diagnostic testing points to the main control board or shorted components, stop and call a certified appliance technician. Working on heater circuits involves live voltages and fire risk if misdiagnosed.

If you’re comfortable with safe, basic electrical checks (power off continuity testing, visual inspections), follow the troubleshooting steps above. Otherwise, contact Samsung-authorized service or a licensed appliance repair professional to diagnose and repair the heater, sensor, or control board safely.
