Samsung Dryer Error Code HE: Troubleshooting Guide

The Logic Verdict

My Take: The HE (or HC) error is a classic “airflow vs. heat” battle. The dryer is getting too hot because the hot air can’t escape. Before you buy any parts, 90% of the time this is solved by cleaning your lint trap and the vent hose behind the dryer. If the airflow is clear and the error persists, then you’re looking at a faulty heating element or thermistor.

What It Means

The HE code (often displayed as hE, HC, hC, 1 HC) stands for Heating Error. It specifically indicates that the internal temperature sensor has detected the dryer is overheating (getting too hot) or, in some cases, not heating correctly due to a sensor fault.

Common Causes

1. Clogged Vent: Lint buildup in the wall duct or the flexible hose behind the dryer is restricting airflow.
2. Dirty Lint Filter: A filter clogged with lint or waxy residue (from dryer sheets) blocking air intake.
3. Faulty Heating Element: The element may be shorted (staying on continuously) or broken.
4. Bad Thermistor: The sensor monitoring the temperature has failed.

Step-by-Step Fix

1. The “Cool Down” Reset

If the dryer just overheated, it might just need a break.

• Unplug: Disconnect power for 3 minutes.
• Cool: Open the door and let the drum cool down.
• Retry: Plug it back in and try a cycle. If the error returns, proceed to cleaning.

2. Deep Clean the Airflow System

Restricted airflow is the #1 cause of overheating.

• Lint Filter: Remove it and wash it with warm water and soap. If you use dryer sheets, a waxy film can form that is invisible but blocks air. Scrub it gently.
• Vent Hose: Disconnect the hose from the back of the dryer. Vacuum it out.
• Wall Duct: Use a vent cleaning brush (or call a pro) to clean the duct leading outside. Ensure the outside flap opens freely.

3. Check the Heating Element (Electric Models)

If airflow is perfect, the heating element might be “grounded” (touching the metal housing), causing it to stay on 100% of the time.

• Unplug: Safety first!
• Access: You’ll need to remove the top and front panels (or back panel depending on model).
• Inspect: Look for broken coils or coils touching the metal case.
• Test: Use a multimeter to check for continuity. If the element has continuity to the metal case, it’s shorted and must be replaced.

4. Gas Supply (Gas Models)

For gas dryers, check the gas shutoff valve to ensure it’s fully open. A failing gas valve coils can also cause erratic heating errors.
