Washer stops during cycle, displays F06 or F6, drum may not turn or may jerk and stop.

Safety first: Unplug the washer before accessing the rear panel or motor. Avoid rotating the drum by hand while power is applied.

Step-by-step:

• Check for overload: Remove some items if the drum is heavily overloaded and try a spin-only cycle. Overloading can trigger motor errors.
• Access rear panel: Remove the rear panel screws and pull off the panel to expose the drive motor and belt.
• Inspect belt and pulley: Ensure the drive belt is on both the motor pulley and drum pulley and is not shredded or extremely loose.
• Check motor harness: Locate the wiring harness at the motor. Unplug and inspect for corrosion, burnt pins, or broken wires. Reseat the connector firmly.
• Inspect MCU (if separate): On models with a separate motor control board, inspect the board for burnt components or discoloration. Check the harness between the CCU and MCU.
• Spin test: With power still disconnected, rotate the drum by hand. It should turn smoothly without grinding or binding. Binding can overload the motor.
• Component replacement: If wiring is intact and the drum turns freely but F06 persists, the motor tachometer or MCU is likely faulty. Replace the motor control board or drive motor as indicated by model-specific diagnostics.

Note: Diagnosing motor and control issues often requires resistance and voltage checks; if you lack a meter, consider a professional technician.
