Washer will not spin or tumble; F06 displayed; may start to move then stop abruptly.

Safety First: Unplug the washer before accessing the rear or bottom. Moving parts can start unexpectedly if power is applied.

Steps:

• Access motor and MCU: Remove rear panel. The drive motor is mounted to the back of the tub; the motor control board (if separate from CCU) is usually near the bottom.
• Inspect wiring: Check the harness from the main control to the MCU and from the MCU to the motor. Look for chafed insulation, burnt connectors, or loose plugs. Reseat all connectors firmly.
• Check motor connector: Unplug the motor connector and inspect pins for corrosion or burning. Clean and reconnect.
• Spin drum by hand: Ensure the drum turns smoothly without grinding or binding, which could overload the motor.
• Test in diagnostic mode: Enter service/diagnostic mode (varies by Kenmore model) and run a spin test. If the motor hums but does not turn, or F06 reappears, suspect the MCU or motor.
• Replace suspect part: If wiring is intact, replace the motor control board first (common failure). If still faulty, replace the drive motor assembly.

Note: This repair often requires meter testing of motor windings and tachometer; if you lack tools or experience, consider a technician.
