Quick answer
9C1, 9E, 2E and 9E1 point to abnormal voltage reaching a Samsung dryer.
Model compatibility: Samsung reuses codes across series and model years, so 9C1 / 9E / 2E / 9E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
9C1 (also 9E, 2E, 9E1) is a voltage error: something is abnormal with the voltage supplied to the dryer.
A 9C1 code (also shown as 9E, 2E or 9E1) tells you something is abnormal with the voltage reaching your Samsung dryer. It applies to Samsung dryers in general.
What Samsung asks you to check
The dryer is on its own circuit and is not using an extension cord.
On an electric dryer, the power cord is installed properly and the correct voltage is supplied.
A model moved to another country from the one where it was sold can show this code, because power grids and rules differ between countries.
The UK list reads 9C1/9E1 as “the electronic control needs to be checked”: confirm power is supplied properly and the cord is plugged in.
Stacked with a washer
With a multi-control kit, the washer may report a 9C1 error for the dryer if you operate the dryer within 5 seconds of switching the washer on. A software update through the SmartThings app corrects it. Install takes about 20 minutes and the dryer does not respond meanwhile.
Related codes
9C2 uses the same electronic-control wording, and AC is the internal communication error.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
