Washer-dryer combo displays E16 and the drum does not rotate during wash or spin, though you may hear a humming sound.

Safety first: Unplug the unit before attempting to rotate the drum or access the motor.

• Check drum movement: Open the door and spin the drum by hand. It should rotate smoothly with minimal resistance. Grinding or stiffness indicates bearing or obstruction issues.
• Inspect for obstructions: Look through drum holes with a flashlight for objects stuck between the inner drum and outer tub (e.g., bra wires). Remove if visible.
• Access motor and belt: Remove the rear panel. Verify the belt is intact and properly tensioned. Remove the belt and test the motor shaft by hand; it should spin freely.
• Test motor capacitor (if present): Locate the capacitor near the motor. If it is bulging or leaking, replace it. Use a capacitance meter to confirm its value if available.
• Motor test: Use a multimeter to check motor windings for continuity. Replace the motor if windings are open or shorted.
• If bearings are seized: Replacing tub bearings and seal is a complex repair often requiring full tub removal. Consider professional service.
