Drying function does not heat; clothes remain wet or only slightly warm after a drying cycle, with E06 displayed.

Safety first: Unplug the washer-dryer and allow it to cool completely before accessing the dryer section. Sharp metal edges may be exposed when panels are removed.

Step-by-step checks:

• 1. Clean lint and condenser: Remove the lower front condenser access (if fitted on your Montpellier model) and rinse the condenser unit under running water to clear lint and fluff. Clean the internal lint filter and ensure the air paths are not blocked.
• 2. Access dryer heater: Remove the top cover and, if necessary, the rear panel. Locate the dryer heater housing, usually mounted behind the drum with multiple wires and thermostats attached.
• 3. Check thermal cut-outs: Identify the thermostats/thermal fuses on the heater housing. With the machine unplugged, test each for continuity. If any are open circuit and non-resettable, replace them. If a resettable thermostat has a small button, press gently to reset.
• 4. Test dryer heater element: Disconnect the heater terminals and measure resistance. If open circuit, the dryer heater is faulty and must be replaced.
• 5. Inspect dryer NTC sensor: Some Montpellier washer-dryers use an NTC sensor in the air duct. Test its resistance at room temperature (typically 20–30 kΩ) and replace if readings are abnormal.
• 6. Restore airflow: Check the fan blower wheel for lint buildup or obstruction. Ensure the fan motor spins freely. Poor airflow can cause overheating and repeated TCO trips.
• 7. PCB and wiring: If all components test OK but E06 persists and no power reaches the heater, the main PCB or wiring harness may be at fault. Professional diagnosis is recommended.
