How do I fix error code 3C on a Samsung washers?

1. undefined: 1. Check motor winding resistance at any two of three terminals: should be 12Ω at 25°C 2. undefined: 2. Check motor connector terminal connections and contacts 3. undefined: 3. Check motor Hall Sensor on main PCB (pins 2-4, 3-4 of four pins): resistance approx 2-4 MΩ 4. undefined: 4. If hall sensor terminal is faulty, replace it 5. undefined: 5. Check stator of motor cover for damage 6. undefined: 6. Check for coil disconnections due to foreign material 7. undefined: 7. If PBA control circuit is faulty, replace PBA 8. undefined: 8. Check motor winding resistance at CN8: Pin1&3 = 11.6 ohms (±7% at 20°C), Pin1&2 = 11.6 ohms, Pin2&3 = 11.6 ohms

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 motor/hall sensor connector; Washing motor rotor and stator fault; Main PCB fault; Motor overloaded (too much laundry); Foreign material in motor

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 motor/hall sensor connector; Washing motor rotor and stator fault; Main PCB fault; Motor overloaded (too much laundry); Foreign material in motor

What actually causes this:

The motor is overloaded, jammed, or a wire came loose

First Thing to Check

Remove some laundry and restart. Check if drum spins freely by hand.
