Washer-dryer combo shows E5 and does not heat water during wash; cycles may run cold.

Safety first: Unplug the appliance and allow internal components to cool before touching.

• Confirm symptom: Run a hot wash cycle and check if the door glass warms up after 15–20 minutes. If not, heating is likely not occurring.
• Access heater: On many Midea combos, the wash heater is mounted at the rear of the drum. Remove the rear panel to locate the heater terminals and NTC sensor.
• Check wiring: Inspect connectors for burning, corrosion, or loose fit. Reseat any loose plugs.
• Test heater resistance: With a multimeter, measure resistance across the heater terminals. An open circuit indicates a failed heater element.
• Test NTC sensor: Measure resistance of the NTC; it should change smoothly with temperature (refer to service data if available). A shorted or open NTC will trigger E5.
• Replace faulty parts: If the heater or NTC is defective, replace with a compatible Midea heater assembly and sensor. If both test good, the main PCB heater relay may be faulty and should be serviced by a technician.
