Samsung Washer HC — What It Means & How to Fix It
Also shown as HE on some models.
The washer's internal water heater ran too hot or its control failed — beyond a single reset, this is a mains-voltage repair that belongs to a technician.
What this code means
HC (HE on older displays) is a heater error: the water temperature climbed abnormally high, or the heating circuit behaved in a way the board flagged as unsafe. Every component it implicates — the element, its relay, the thermistor feeding it — operates on mains power inside the sealed base of the machine.
HC means this heater fault on washers; on Samsung dryers an HC-family code relates to venting instead. Confirm you're reading the washer's display, and check your model's manual if anything seems off.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Heating element failing or scaling up (runs hot before dying) | Common | No — technician job |
| Thermistor under-reporting, letting the heater overrun | Common | No — technician job |
| Heater relay stuck on the control board | Occasional | No — technician job |
| One-off sensor glitch | Occasional | Yes — power reset only |
What you can try yourself
- Unplug the washer, wait ten minutes, and run a cold cycle. If even cold cycles trip HC, stop — the fault is electrical, not thermal.
- If the cold cycle passes, try one warm cycle. A single clean run suggests a transient misread; a returning HC ends the DIY road.
- Book a technician for anything beyond this. The heater and its wiring are mains-voltage parts in a wet environment — exactly the combination this site never gives DIY steps for.
- Meanwhile, note any history of scalding-hot washes or steam from the detergent drawer — that detail tells the technician whether the heater overran for a while before the code appeared.
When to call a technician
- HC returns after one reset — that's the line; no further user-side checks exist.
- Burning smells, a tripped breaker, or steam from the machine: leave it unplugged entirely.
- Laundry coming out unusually hot on warm settings even without the code.
Typical professional repair cost: Heating element replacement typically runs $150–$300 with labor; thermistor or relay repairs somewhat less.
Frequently asked questions
Why does my washer even have a heater — isn't hot water from the tap?
Most modern Samsung front-loaders fill cold and heat internally for precise temperature control and lower energy use. That internal element is what HC is complaining about — and why the fault doesn't go away if your home's water heater is fine.
Can I bypass the heater and wash cold?
No — and don't let anyone disconnect it informally. The board expects the heater circuit to be present and behave; a recurring HC means a component is misbehaving on mains power, which deserves a proper repair, not a workaround.
Does hard water cause HC errors?
It accelerates them. Scale insulates the element so it runs hotter for the same output, stressing both the element and the accuracy of the temperature reading next to it. In hard-water areas, elements simply live shorter lives.
