Error codeCb, C6
ApplianceWasher
Not a fault
Cb and C6 tell you the washer is in Calibration mode. The mode resets how the washer senses load weight, which sets how much water each cycle draws. Calibration normally comes as one of the last steps of an installation. The listing covers every washer.
What to expect
The tub or drum turns back and forth for 1 to 3 minutes.
The mode then ends without your help.
It only calibrates correctly if the washer is empty, so remove anything inside and run it once more.
Washer service if Calibration mode will not finish
When the code keeps coming back on an empty machine, San Francisco and Bay Area owners can phone (415) 969-6153. Samsung washer repair is described online. Tell us the code, the model number, and that you ran the mode empty.
Model compatibility: Samsung reuses codes across series and model years, so Cb, C6 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
Calibration mode: the washer recalibrates its weight detection in 1 to 3 minutes and stops by itself.
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.
