Samsung Washer Error Code 9C1

The 9C1 code means the washer has detected an incorrect operating voltage, either too high or too low, coming from the power supply. It can also appear when a faulty wall outlet causes a voltage drop under load, or when the main PBA has a fault. The washer triggers this code as a protective measure to prevent damage to its electronics and motor.

You should not continue operating the washer while this code is active. The error indicates the machine is receiving power outside its safe operating range, which can damage internal components over time. Resolve the power supply issue before resuming use.

If the problem is the wall outlet or home wiring, repair costs typically range from a low outlet replacement fee up to several hundred dollars for more involved electrical work, depending on the scope. If the main PBA is at fault, board replacement parts and labor can range from roughly $150 to $400 or more depending on the model and service provider.

In many cases, yes. Start by confirming the washer is plugged directly into a dedicated wall outlet and not an extension cord. Test the outlet voltage with a multimeter to verify it is supplying correct, stable voltage. If the outlet and home wiring check out and the error persists, the main PBA may need professional diagnosis or replacement.

A reset may temporarily clear the code, but it will return if the underlying cause is not corrected. If the outlet voltage is out of range or the outlet itself is faulty, the washer will detect the same condition on the next cycle and display the error again. Address the root cause before relying on a reset.
