Washer-dryer shows E23 and will not drain or complete cycle on Xiaomi combo washer-dryer.

Safety first: Unplug the appliance and prepare for water spillage when accessing the pump.

• 1. Clean pump filter: Open the lower front access panel, remove the drain filter, and clear any debris. Check that the impeller can rotate freely.
• 2. Listen for pump operation: Run a drain cycle and listen. If the pump is silent and E23 appears quickly, suspect an electrical fault.
• 3. Inspect wiring: Remove the bottom or rear panel to access the Xiaomi drain pump. Check the connector for secure fit and no signs of burning.
• 4. Test pump resistance (advanced): With a multimeter and power disconnected, measure resistance across the pump terminals. An open circuit or very low resistance indicates a failed pump that must be replaced.
• 5. Control board check: If a known-good pump still triggers E23, the control board's pump driver or relay may be damaged. Board-level repair should be done by a professional.
