Washer-dryer stops during drying cycle, no heat or very low heat, E8 displayed on Xiaomi combo washer-dryer.

Safety first: Unplug the unit. Dryer circuits involve high temperatures and mains voltage.

• 1. Clean lint and airflow paths: Remove and clean any accessible lint filters. On Xiaomi condenser-type combos, access the condenser unit (usually via a lower front panel) and rinse or brush off lint and dust. Ensure air inlets and outlets are not blocked.
• 2. Avoid overloading: Dry smaller loads to allow proper air circulation. Overloading can cause overheating and trigger safety devices.
• 3. Access dryer heater (advanced): Depending on the Xiaomi model, the dryer heater may be located at the rear or side of the drum housing. Remove the top and rear panels to locate the heater assembly, thermostats, and NTC sensor.
• 4. Check continuity: With a multimeter and power disconnected, test the dryer heater, thermal fuse, and thermostats for continuity. Replace any open components with Xiaomi-specified parts.
• 5. Inspect wiring: Ensure all connectors to the heater and sensors are secure and not heat-damaged.
• 6. If E8 persists: The dryer control circuit on the main PCB may be faulty. Due to complexity, contact a qualified technician for further diagnosis.
