Samsung Dryer HE Error Code
Heating system not reaching target exhaust temp
What this error means
HE (hE on some displays) logs when exhaust temperature fails to climb during a heat cycle. Samsung disables the element or gas valve as protection—restricted vent airflow is the most common trigger before any part failure.
How HE is detected
HE on Samsung dryer units indicates the drive system did not meet expected performance. Direct-drive washers monitor rotor position with a hall sensor; dryers and dishwashers track motor current draw. When the drum or spray arm fails to turn, the inverter or motor relay shuts down to prevent burned windings. Samsung DVE45R6100W, Samsung DV42H5000EW, and similar variants may show this fault after an overloaded tub or a foreign object jam.
Clogged lint screen or vent run raising exhaust temp slowly is a leading trigger. Start with clean the lint filter and vacuum the vent hose from both ends. Rotate the drum or spray arm by hand when powered off—it should move without grinding. Grinding confirms mechanical obstruction; free rotation with repeated HE on light loads suggests hall sensor, motor, or inverter board failure requiring professional diagnosis.
Common causes
- Clogged lint screen or vent run raising exhaust temp slowly
- Blown thermal fuse on the heater housing after prior overheat
- Open electric heating element or weak gas igniter glow
- Faulty thermistor sending low readings to the control
Step-by-step fixes
- 1Clean the lint filter and vacuum the vent hose from both ends
- 2Run a timed dry on high heat and feel airflow at the exterior hood
- 3Replace the thermal fuse only after confirming the vent is clear—otherwise it blows again
- 4On gas models watch for igniter glow without flame—gas valve or coils may follow
When to call a technician
Clear vent with good fuse continuity but persistent HE needs thermistor, element, or gas valve diagnosis with live voltage tests.
Affected models
- Samsung DVE45R6100W
- Samsung DV42H5000EW
- Samsung DVE50R5400V
Prevention & maintenance
- Avoid washing single heavy rugs or shoes that bind the drum; distribute weight evenly to reduce motor strain that precedes HE.
- Record when HE appears in the cycle and whether it clears after a 60-second power reset on your Samsung dryer—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for HE; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting HE; reversed plugs on pumps and valves cause immediate repeat faults.
