Safety first: Unplug the washer and shut off water supply. Heating components can retain residual voltage—use caution.

Run a cold-only cycle: Set the washer to a cold wash. If E5 does not appear, the issue is likely with the heater or temperature sensing circuit.
Access the heater: On many Haier front-load models, the heater is mounted at the rear of the tub and accessible from the back panel. Remove the rear cover to expose the heater terminals and NTC sensor.
Check wiring: Inspect connectors for corrosion, burning, or looseness. Reseat all plugs firmly.
Test the heater: With a multimeter, measure resistance across the heater terminals. Compare to Haier specifications (typically 20–30 Ω; check service manual). Replace the heater if open or shorted.
Test the NTC sensor: Measure resistance at room temperature and again in warm water; it should change smoothly. Replace the NTC if readings are erratic or out of spec.
If all components test good: The main PCB may not be driving the heater correctly and may require replacement by a qualified technician.

Washer displays E5; water temperature is abnormal or heating function fails.
