WF42H5000AW
Most Samsung front-load washers with built-in heaters

Common Causes

Failed heating element (burned out or shorted)
Faulty temperature sensor (thermistor) giving wrong readings
Control board sending incorrect power to the heater
Wiring problem between the heater and the control board
Scale or mineral buildup on the heating element

How to Fix It

Turn off the washer and unplug it from the wall outlet.

Always disconnect power before doing anything. This is a safety issue involving a heating element.
Wait 10 to 15 minutes, then plug the washer back in.

Sometimes a temporary sensor glitch triggers the error. A full power reset can clear it.
Run a cold-water-only cycle to test.

Select a cycle that uses cold water. If the error doesn't appear, the problem is with the heating system.
Check your home's hot water supply by running the nearest faucet.

If your home has no hot water, the washer may be overworking the heater to compensate. Fix your water heater first.
If the error returns on any cycle, call a technician.

The heating element, thermistor, or control board likely needs replacement. These are not safe DIY repairs.

When to Call a Professional

The HE1 error almost always requires a professional repair. Do not attempt to access the heater yourself — it involves electrical components. Contact Samsung support or a licensed appliance technician. Expect repair costs of $200–$400 depending on whether the heater or control board needs replacing.

Frequently Asked Questions

What does the heater in a Samsung washer do?

Many Samsung washers have a built-in heater to warm wash water. This is separate from your home's hot water heater. It heats water inside the drum for cycles that need warm or hot water. The HE1 error means this internal heater has a problem.

Can I use my Samsung washer with the HE1 error?

You should not continue using it until the error is resolved. The heater could be overheating, which is a safety risk. You may be able to run cold-water cycles temporarily. But get it inspected by a technician as soon as possible.

Is the HE1 error covered under Samsung warranty?

If your washer is within the standard warranty period, yes. Samsung offers a 1-year parts and labor warranty on most models. Some models have extended warranties on specific parts. Check your purchase date and contact Samsung support to verify coverage.
