Washer-dryer fails to heat water; cycle may run long and end with E06.

Safety first: Unplug the appliance. Heating components can retain heat; allow cooling time before handling.

• Step 1 – Confirm no heating: Run a 60°C wash and check the door glass after 20–30 minutes. If it remains cold and E06 appears, suspect a heating fault.
• Step 2 – Access heater: Remove the rear panel to locate the wash heater element mounted in the outer tub. Inspect for signs of burning or limescale buildup around the seal.
• Step 3 – Test heater resistance: Disconnect the heater wires and measure resistance across the heater terminals. Typical values are 20–30 Ω. An open circuit or very high resistance indicates a failed heater that must be replaced.
• Step 4 – Check earth leakage: Measure resistance between each heater terminal and the metal casing. A low resistance reading suggests insulation breakdown; replace the heater.
• Step 5 – Inspect wiring and connectors: Look for heat-damaged spade terminals or melted insulation. Replace any burnt connectors and ensure tight, clean contacts.
• Step 6 – Control PCB relay: If the heater tests good but never receives mains voltage during heating, the heater relay or PCB track may be faulty. This requires PCB repair or replacement, best handled by a qualified technician.
