Washer does not heat water; cycles take unusually long or stop; E05 displayed on CDA washing machine.

Safety first: Disconnect the appliance from the mains before accessing internal components. Heating elements can retain heat after use.

• Access the heater: Remove the rear panel to expose the heater terminals at the bottom of the tub.
• Test the element: Measure resistance across the terminals. Typical values are 20–30 Ω. An open circuit indicates a failed element.
• Check for earth leakage: Measure resistance between each terminal and the metal chassis. Any low resistance suggests insulation breakdown—replace the heater.
• Inspect the NTC sensor: Measure its resistance at room temperature (often 20–30 kΩ). If it reads open or shorted, replace it.
• Examine wiring and PCB: Look for burnt connectors. If the heater and sensor are good, the PCB heater relay may be defective.
• Replace parts as needed: To replace the heater, loosen the central nut, push the bolt in, and pull the element out. Fit the new heater and test for leaks.
