Drying cycle runs but clothes remain wet or only slightly warm; E11 may appear mid-cycle.

Safety: Disconnect mains power before cleaning internal ducts or fan assemblies.

• Clean lint paths: Remove the lower front kick panel or rear panel (depending on Belling model) and access the condenser/air duct. Vacuum out lint and fluff from ducts, condenser channels, and around the fan housing.
• Check fan operation: Start a drying cycle briefly (with panels safely in place) and listen for the dryer fan. If silent, unplug and access the fan motor. Check for obstructions in the impeller and test the motor for continuity. Replace the fan motor if open circuit or seized.
• Inspect condenser (if condenser-type): Remove the condenser unit (if user-removable) and rinse thoroughly under running water to clear lint and detergent residue. Allow to dry and refit.
• Thermal devices: Overheating due to blocked airflow can trip thermostats. After cleaning, reset any manual-reset thermostats if fitted (small red button on some TCOs).
• Persistent E11: If airflow is clear and fan runs but E11 persists, the dryer temperature sensing circuit or PCB may be faulty. Professional service is advised.
