Samsung tumble dryer HC error code
What HC means on a Samsung tumble dryer
Heat pump fault, often linked to blocked airflow or the heat exchanger not reaching temperature.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When your Samsung tumble dryer shows the HC code, it is reporting a fault with its heat pump, the part that warms the air used to dry your clothes. This is often linked to the air not flowing freely through the dryer, or to the heat exchanger not reaching the temperature it should. You will usually notice that the dryer is not heating, so your laundry comes out damp.
Engineers sometimes find that the lint filters have become clogged, glazed over or worn out, which chokes the airflow. They also sometimes find that the thin metal fins on the heat exchanger have been bent or squashed flat, which stops air passing through properly.
An engineer will typically check the filters and the heat exchanger, clean out the inside of the dryer and test that everything works safely. Bent fins can often be straightened and the dryer reset on the spot. Worn or damaged filters are replaced, and as new ones may need to be ordered, this can sometimes mean a second visit to fit them before the dryer is back to heating properly.

Before you check anything yourself
- Switch the tumble dryer off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the tumble dryer apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
