# How to Fix Samsung Washing Machine Error HE (Heating Error)
The Samsung HE error code indicates a failure in the heating system. This issue is most common in Samsung Washer/Dryer Combo units where the drying cycle cannot generate sufficient heat.

## What Does the Samsung HE Error Code Mean?
The **HE** code stands for **Heating Error**.
The washing machine’s Main Control Board (PCB) registers this error when the temperature sensor (thermistor) reports one of three issues:
1. The machine tried to reach a target temperature (usually during a drying cycle or sanitize wash) but failed to heat up within the allotted time.
2. The temperature detected is abnormally high, indicating an overheating condition (often due to a failed thermal fuse or a constantly engaged relay).
3. The thermistor (temperature sensor) itself has failed and is reporting an open circuit or an unrealistic reading.
In Samsung Washer/Dryer combos, the most frequent mechanical cause for this error is a **failed Dryer Heating Element**.

## Step-by-Step Troubleshooting and Diagnosis
**Warning:** Before performing any electrical diagnostic tests or removing panels, you must unplug the machine from the power outlet and turn off the water supply. This repair involves intermediate electrical diagnosis skills and tools (specifically a multimeter).
### Step 1: Perform a Power Reset
Sometimes the HE error is a temporary glitch triggered by a power surge or an interrupted cycle.
1. Unplug the washing machine completely for 5 to 10 minutes.
2. Plug the machine back in.
3. Attempt to run a short wash cycle, or specifically, a dry-only cycle (if applicable).
4. If the code returns, proceed to the hardware inspection.
### Step 2: Access the Dryer Heating Element
The dryer heating element is typically located on the **back side** of a combo unit.
1. **Unplug the unit.**
2. Pull the machine away from the wall to access the rear panel.
3. Using a screwdriver (often Philips head or nut driver), remove the screws securing the **main rear panel**.
4. Carefully remove the panel. You should now see the ductwork that houses the heating elements and thermistors.
### Step 3: Visually Inspect Components
The HE error may be caused by related safety components that fail before the element itself.
1. **Check Wiring:** Look for obvious signs of burnt, melted, or disconnected wires leading to the element or surrounding components.
2. **Inspect the Thermal Fuses/Thermostats:** The heating assembly usually contains a thermal fuse (small white or gray cylindrical device) and possibly a high-limit thermostat. If the fuse is blown or looks scorched, it has tripped, and the element will not receive power.
### Step 4: Test the Dryer Heating Element (The Main Culprit)
You must use a multimeter set to **Ohms (Ω)** to test the continuity and resistance of the element.
1. **Locate the Heating Element Terminals:** The element will have two main terminals where the power wires connect. Remove the wires leading to these terminals.
2. **Place Multimeter Probes:** Place one multimeter probe on each terminal of the heating element. Do not let the probes touch the metal chassis.
3. **Read the Resistance:**
* **Good Element:** A working element will show resistance, typically between **10 and 50 Ohms**. (The exact number depends on the model, but a reading in this range indicates the element coil is intact.)
* **Bad Element:** If the multimeter reads “OL” (Open Loop/Infinite Resistance) or “1,” the circuit is broken. The element has failed and must be replaced.
> **Note:** If the element itself tests fine, you should also test the thermal fuse and thermistor for continuity. If they show “OL,” they are the failed part, causing the HE error.
### Step 5: Replace the Heating Assembly
If the dryer heating element (or the thermal fuse/thermostat assembly) tests bad (showing OL resistance), you need to replace it.
1. Remove the mounting screws holding the heater assembly to the ductwork.
2. Carefully pull the faulty assembly out.
3. Install the new element assembly, ensuring all gasket seals are properly seated.
4. Reconnect the wiring exactly as it was before removal.
5. Reattach the rear panel, plug the machine back in, and run a test cycle.
