Washer-dryer overfills or shows E7, water level seems incorrect or machine stops mid-cycle on Xiaomi combo washer-dryer.

Safety first: Disconnect power and close water taps before opening the cabinet.

• 1. Cancel and drain: If the drum is overfilled, use the drain program to remove water. If the machine will not respond, unplug it and manually drain via the filter.
• 2. Access pressure sensor: Remove the top cover. Locate the Xiaomi pressure sensor (small round or rectangular device) connected to a thin rubber hose from the tub.
• 3. Inspect and clear hose: Detach the hose from the sensor and gently blow through it toward the tub. It should be clear. If blocked, remove the hose and clean it and the air trap connection on the tub of sludge or detergent buildup.
• 4. Check sensor connection: Ensure the electrical connector is firmly seated on the pressure sensor and that no pins are corroded.
• 5. Test again: Reassemble, restore power, and run a short cycle. If E7 returns, the Xiaomi pressure sensor may be defective and should be replaced.
• 6. Advanced: Replacement of the sensor is straightforward (unplug, swap, reconnect), but if the fault persists, the main control board may be misreading the signal and will require professional service.
