What does the error mean?

The Samsung top load washer error code 3C typically indicates an issue with the washing machine’s motor or motor control system. Here are the possible causes for this error code:

• Motor fault: The washing machine’s motor may have developed a fault, such as a winding issue or a mechanical problem, preventing it from operating properly.
• Motor hall sensor fault: The hall sensor, which is responsible for monitoring the motor’s rotation, may have failed or is sending incorrect signals to the main control board.
• Incorrect connections: The wiring harness or connectors between the washing motor, hall sensor, and the main control board may be loose, damaged, or incorrectly connected, interrupting the communication between these parts.
• Motor rotor and stator fault: The rotor and stator, which are the main components of the washing machine’s motor, may have developed issues, such as wear and tear or electrical problems, affecting the motor’s performance.
• Main PCB fault: The main control board (PCB) that manages the overall operation of the washing machine may have a fault, leading to issues with the motor control and sensing functions.

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Don’t test wiring with a multimeter for live voltage if you’re unfamiliar with how to prevent short circuiting when testing. 
• Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts. 

Tools and materials

• Multimeter
• Screwdrivers
• Cleaning supplies

Important: The specific tools required may vary depending on the model of your appliance and the type of fasteners used on it. Always consult the user manual or refer to any specific instructions provided by the manufacturer for the recommended tools for your appliance model.

Troubleshooting steps

Overloading:

1. Reduce the amount of laundry in the washing machine and try the wash cycle again.
2. Overloading can cause the motor to become overworked, leading to increased power consumption and potential damage.

Check the wiring:

1. Remove the access panel on the back of the washing machine to access the main control board. This is usually secured with screws.
2. Visually inspect the terminal connections and contacts on the motor connector. Ensure they are clean, tight, and free of any corrosion or damage.
3. Verify the connector is securely seated, and the terminals are making proper contact.

Test the motor winding coil:

1. Locate the motor, which is typically at the bottom of the washing machine.
2. Remove the rear panel or any necessary parts to access the motor terminals.
3. Carefully inspect the motor windings and connections for any signs of foreign material, such as lint, dust, or debris.
4. Using a multimeter, measure the resistance between any two of the three motor terminals.
5. The resistance should be around 9.3 ohms (at 25°C).
6. If the measured resistance is significantly different, it may indicate a winding issue, and the motor may need replacement.

Test the hall sensor:

1. Remove the access panel on the back of the washing machine to access the main control board and locate the motor hall sensor connector on the control board.
2. Measure the resistance between pins 2 and 4, and between pins 3 and 4 of the four-pin hall sensor connector.
3. The resistance should be approximately 2 to 4 MΩ.
4. If the resistance is out of this range, the hall sensor may be faulty and will need replacement.

Check the PBA (printed board assembly):

1. Locate the access panel on the back of the washing machine to access the main control board (PBA).
2. Remove the access panel and carefully inspect the PBA for any visible signs of damage, such as burned or discolored components, loose connections, or other abnormalities.
3. If the PBA control circuit is found to be faulty or no other parts test bad, the PBA will need to be replaced.
