Error Code 3C

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

The washer's motor cannot spin or is struggling to turn. 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; PBA fault — motor driving signal from PBA is weak; Unstable relay operation; 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; PBA fault; 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; PBA fault — motor driving signal from PBA is weak; Unstable relay operation; 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; PBA fault; DD motor fault

What actually causes this:

Most commonly caused by an overloaded drum — too many clothes or heavy items.

First Thing to Check

Reduce the laundry load by removing some items and restart the cycle.
