Washer-dryer drum does not spin or spin is very weak, E3 displayed on Xiaomi combo washer-dryer.

Safety first: Disconnect power before removing any panels. Spinning components can cause injury.

• 1. Reduce load and retry: Overloading can trigger motor protection. Remove some laundry, redistribute the load, and run a spin cycle again.
• 2. Listen for motor activity: If you hear humming but no spin, the belt may be slipping or off (if your Xiaomi model uses a belt). If there is no sound at all, the motor or inverter may not be energizing.
• 3. Inspect the drive belt (if applicable): Remove the rear panel. Check if the belt is intact and properly seated on both the motor pulley and drum pulley. Refit or replace if frayed or broken.
• 4. Check drum movement: Rotate the drum by hand. It should move smoothly without grinding. Stiff movement may indicate bearing or mechanical seizure, which can overload the motor.
• 5. Advanced electrical checks: With power disconnected, inspect wiring harnesses between the Xiaomi BLDC motor, hall sensor, and inverter board for loose plugs or damage. Electrical testing of motor windings and hall sensor should be done with a multimeter by a qualified technician.
• 6. If E3 persists: The Xiaomi drive motor or inverter PCB may require replacement. Due to high-voltage and complex electronics, professional service is strongly recommended.
