Error Code 3C

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

The washer's motor cannot spin properly Motor spin net is not engaged; Motor internal coil is damaged (short-circuited or cut); Hall sensor terminal is not connected; Foreign material (e.g., a screw) has entered the motor; Motor overloaded due to too much laundry (non-sensing); Motor hall sensor terminal is not connected; Main PBA fault; Motor driving signal from the PBA is weak; Unstable relay operation on the Main PBA; Erroneous operating signals from the motor hall sensor; IPM terminal of the main PBA is not connected; DD motor cover is out of place; PCB housing terminal is not connected; DD motor fault

What This Means

Motor spin net is not engaged; Motor internal coil is damaged (short-circuited or cut); Hall sensor terminal is not connected; Foreign material (e.g., a screw) has entered the motor; Motor overloaded due to too much laundry (non-sensing); Motor hall sensor terminal is not connected; Main PBA fault; Motor driving signal from the PBA is weak; Unstable relay operation on the Main PBA; Erroneous operating signals from the motor hall sensor; IPM terminal of the main PBA is not connected; DD motor cover is out of place; PCB housing terminal is not connected; DD motor fault

What actually causes this:

Usually caused by overloading the washer with too much laundry, or a worn-out motor

First Thing to Check

Remove some laundry to reduce the load and restart the cycle — overloading is the most common cause
