Washer-dryer stops during wash or rinse with E05; water may be cold when it should be hot.

Safety first: Unplug the appliance and allow it to cool before working near the heater.

• Check water temperature: Run a 60°C wash and feel the door glass after 15–20 minutes (do not burn yourself). If it remains cold and E05 appears, suspect a heating fault.
• Access heater terminals: Remove the rear panel (or front lower panel depending on model). Locate the heater element at the bottom of the tub with two power terminals and an earth connection.
• Inspect wiring: Look for burnt connectors or loose spade terminals. Reseat any loose connections.
• Basic continuity check (if you have a meter): With power disconnected, measure resistance across the heater terminals. A typical value is 20–40 Ω. Infinite resistance indicates a failed heater.
• Check NTC sensor: The temperature sensor is usually mounted in or near the heater bracket. Ensure its connector is firmly seated.
• Replace parts as needed: If the heater is open-circuit or visibly damaged, replace it with a Bush-compatible heater element (ensure correct wattage and shape). If the heater tests good but E05 persists, the NTC sensor or control PCB may be faulty and should be diagnosed further by a technician.
