Washer displays E12; heating function fails or water does not reach target temperature.

Safety first: Unplug the washer and allow it to cool before accessing the heater area.

• Access heater: On many Midea front-loaders, the heater is located at the bottom rear of the tub, accessible from the rear panel.
• Check wiring: Inspect the heater terminals and NTC sensor connector for burns or loose connections. Reseat connectors.
• Test heater: Disconnect the heater wires and measure resistance with a multimeter. A typical value is 20–30 Ω (check service manual). Infinite or very low resistance indicates a faulty element.
• Test NTC sensor: Measure resistance at room temperature; compare to Midea specifications. If readings are out of range or do not change with temperature, replace the sensor.
• Replace components: If the heater or NTC is defective, install a compatible Midea heater assembly and/or sensor, ensuring the gasket seats properly to prevent leaks.
