9C1 Samsung dryer error 9C1 — power supply

What it means

If your Samsung dryer shows 9C1: the appliance detected mains voltage that is too low or too high, or a power interruption.

Likely causes

Voltage fluctuations at home, a weak extension lead or socket, power cut.

Safe steps you can try

Plug the appliance straight into a wall socket (no extension), restart the program once voltage is normal. Use a voltage stabiliser if it happens often.

When to call a technician

If the error appears with normal voltage, the power supply and control board need checking.
