Error Code 9C1

Q: What does error code 9C1 mean on a Samsung washers?

The washer is not getting enough electrical power Under voltage supplied to the washer; Plug receptacle being used (voltage drop through extension cord); Connecting wire longer than 1 meter causing up to 10V momentary voltage drop; Main PBA fault

The washer is not getting enough electrical power

Critical

Stop using immediately - risk of damage or safety issue

Also displayed as: 9C1 (upper) / 9C1 (lower)

What This Means

Under voltage supplied to the washer; Plug receptacle being used (voltage drop through extension cord); Connecting wire longer than 1 meter causing up to 10V momentary voltage drop; Main PBA fault

What actually causes this:

The washer is plugged into an extension cord or a weak outlet that can't deliver full voltage

First Thing to Check

Make sure the washer is plugged directly into a wall outlet, not an extension cord or power strip
