Samsung Washer HC Error — Heater Fault Fix

What it means

Samsung washer HC error means there's a fault with the water heater — Samsung's 'Heater error'.
The water isn't reaching the target temperature for a hot or warm wash.
Most cases are a heater element that's failed or scaled up, but the temperature sensor or wiring can also cause HC.

Affected Models

Samsung Front Load Washer
Samsung Top Load Washer
Samsung AddWash Washer
Samsung EcoBubble Washer
Samsung QuickDrive Washer

Common Causes

Heater element burned out (open circuit)
Heater element scaled up — won't transfer heat to water
Temperature sensor (NTC thermistor) faulty
Wiring loose between heater and control board
Control board fault driving the heater incorrectly

How to Fix It

Run a cold-only wash to confirm.

Try a cold wash cycle.
If it completes without HC, the heater is the culprit (cold doesn't use it).
If HC still appears on a cold wash, the temperature sensor or control board is at fault, not the heater itself.
Check household power supply.

Heaters draw 2 kW.
If your circuit can't sustain that — old wiring, undersized fuse — the heater may not get full power and trip HC.
Try the washer on a different circuit if possible.
Run a service / descale cycle.

Most Samsung washers have a Self Clean or Eco Drum Clean cycle.
Run it with a descaling tablet or a cup of white vinegar.
Heavy limescale on the heater element can prevent heat transfer and trigger HC; descaling restores it.
Replace the heater (technician).

If cold washes work and Self Clean doesn't help, the heater element needs replacement.
Contact Samsung support or an independent washing-machine engineer; a typical replacement is 45–60 minutes.
Buy a Samsung-branded element to fit the original mounting.

When to Call a Professional

Heater replacement is moderately involved — usually a technician job unless you're comfortable opening the back of a washing machine.
The element costs around £20–£40; labour adds the rest.

Frequently Asked Questions

Is Samsung HC error the same as HE?

Yes — same fault, different display generation.
HE was used on older Samsung washers; HC is the newer alphanumeric form.
Both are Samsung's 'Heater error' and the fix is identical: confirm with a cold wash, descale, then replace the element.
