Washer-dryer combo displays E31 and may not fill or may overfill; water level readings are erratic.

Safety first: Unplug the unit before accessing the sensor and wiring.

• Inspect pressure hose and chamber: As with E7, ensure the hose is clear and the air chamber on the tub is not clogged.
• Check wiring harness: Verify the connector at the Midea analog pressure sensor is secure and wires are not pinched or cut.
• Sensor replacement: If hoses and wiring are good but E31 persists, replace the pressure sensor with the correct Midea part.
• Service mode (if available): Some models allow sensor calibration in service mode; refer to service documentation. Incorrect calibration should be handled by a technician.
