Error Code 3C

Q: What does error code 3C mean on a Samsung washers?

The washing machine motor is not spinning properly. PBA connector terminal not connected; Motor spin net not engaged; Motor internal coil damaged (short-circuited or cut); Foreign material (screw) entered the motor; Foreign material between pulsator and bowl constraining motor; Motor overloaded due to too much laundry (3C1); PBA fault — weak motor driving, unstable relay (3C2); IPM terminal of main PBA not connected (3C3); DD motor cover out of place (3C3); PCB housing terminal not connected (3C4); DD motor fault (3C4); Pulsator motor fault (3CP)

The washing machine motor is not spinning properly.

What This Means

PBA connector terminal not connected; Motor spin net not engaged; Motor internal coil damaged (short-circuited or cut); Foreign material (screw) entered the motor; Foreign material between pulsator and bowl constraining motor; Motor overloaded due to too much laundry (3C1); PBA fault — weak motor driving, unstable relay (3C2); IPM terminal of main PBA not connected (3C3); DD motor cover out of place (3C3); PCB housing terminal not connected (3C4); DD motor fault (3C4); Pulsator motor fault (3CP)

What actually causes this:

Usually caused by an overloaded drum (too much laundry), a stuck foreign object jamming the drum, or a loose wiring connector at the motor.

First Thing to Check

Reduce the laundry load to about half, then try running the cycle again.
