Error Code 3C

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

The washer's motor isn't working Washing motor fault; Washing motor hall sensor fault; Incorrect connections of washing motor/hall sensor connector; Washing motor rotor and stator fault; Main PCB fault; Overloading due to too much laundry

The washer's motor isn't working

Critical

Stop using immediately - risk of damage or safety issue

Also displayed as: 3C

What This Means

Washing motor fault; Washing motor hall sensor fault; Incorrect connections of washing motor/hall sensor connector; Washing motor rotor and stator fault; Main PCB fault; Overloading due to too much laundry

What actually causes this:

The motor wiring came loose or the motor itself has failed

First Thing to Check

Unplug the washer, wait 60 seconds, and try again
