Washer-dryer combo drum does not spin or tumble; unit may fill and drain but shows E3 when trying to spin.

Safety first: Disconnect power before removing any panels. Do not bypass safety interlocks.

• Check for overloading: Remove excess laundry and redistribute the load. Restart a spin cycle to rule out simple overload protection.
• Inspect drive belt: Remove the rear panel. Locate the drive belt around the motor pulley and drum pulley. Ensure the belt is not broken, off-track, or heavily worn. Re-seat or replace if necessary.
• Check motor connections: With power unplugged, inspect the motor wiring harness and connectors for burns, looseness, or corrosion. Firmly re-seat all connectors.
• Manual drum rotation: Spin the drum by hand from the front. It should rotate smoothly. If it is very stiff or grinding, there may be a bearing or mechanical obstruction issue rather than an electrical motor fault.
• If E3 persists: The drive motor or motor control circuit on the main control board may be defective. Testing requires a multimeter and knowledge of live voltage diagnostics. For safety, contact a qualified technician to test and replace the motor or PCB as needed.
