Does this guide apply to your appliance?
Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.

Likely causes
- Washing machine drum is overloaded with excessive or heavy laundry
- Foreign object wedged between the drum and tub obstructing movement
- Temporary electronic communication glitch or locked rotor condition
- Defective drive motor Hall sensor or loose motor wiring harness
- Faulty drive motor or inverter/main control board
What to try
Perform a Mains Power Reset
Easy- Switch off the washing machine using the Power button.
- Unplug the power cord from the mains wall socket (or switch off the circuit breaker).
- Wait at least 1 to 3 minutes to allow residual power to drain from the electronic boards.
- Plug the washing machine back into the wall outlet.
- Power on the machine and start a new, short cycle (such as Rinse & Spin) to verify if the code clears.
Reduce Load and Check Drum for Obstructions
Easy- Ensure the cycle is paused and the appliance is switched off at the mains.
- Open the door and inspect the load size; remove bulky or excess wet laundry if the drum is tightly packed.
- Rotate the drum manually by hand; verify that it spins smoothly without excessive resistance, grinding noises, or sticking.
- Inspect the gap between the drum edge and rubber door seal (gasket) for trapped coins, bra wires, or small clothing items.
- Close the door, restore power, and run a dedicated Spin cycle with a lighter, balanced load.
Isolate Appliance and Schedule Professional Service
ProfessionalThis is a service referral, not a do-it-yourself repair procedure.
- If the 3C code reappears after resetting and adjusting the load, switch off the machine.
- Disconnect the machine from the mains electrical socket.
- Turn off the cold and hot water supply isolation taps to prevent unattended filling.
- Record the exact model number and serial number from the rating label (usually located inside the door frame).
- Contact an authorized Samsung service center or certified appliance engineer to inspect internal motor windings, Hall sensor feedback, and control electronics.
