Washer-dryer combo displays E16 and stops; motor may hum but drum does not move.

Safety first: Disconnect power before spinning the drum by hand or accessing internal components.

• Reduce load: Remove some items from the drum and attempt a spin cycle again to rule out simple overload.
• Check for obstructions: Rotate the drum by hand. If you feel scraping or binding, inspect the gap between the drum and door gasket for trapped items (e.g., bra wires, coins). Remove any foreign objects.
• Inspect bearings: Listen for grinding noises when spinning the drum by hand. Excessive noise or stiffness suggests bearing failure, which may require tub and bearing replacement.
• Motor test: Access the motor and belt. Ensure the belt is correctly tensioned and not slipping. If the motor hums but cannot turn the drum even with a reduced load, the motor may be weak and require replacement.
