Safety first: Disconnect from mains and allow the unit to cool before cleaning.

Step-by-step checks:

Clean condenser: Access the condenser (often behind a lower front panel). Remove it if it is a removable cassette type and rinse thoroughly under running water to clear lint and fluff. Allow to dry before refitting.
Inspect fan and ducts: Remove the rear or side panel to access the dryer fan housing. Clean lint from the fan blades and ducts. Ensure there are no obstructions.
Check fan motor: Spin the fan by hand; it should rotate freely. If stiff or noisy, the fan motor may be failing. Test for proper voltage during a dry cycle (qualified persons only) and replace the fan motor if not running.
Reassemble and test: After cleaning, run a timed dry cycle and monitor airflow and temperature.

When to call a technician: If the fan motor or internal ducting requires major disassembly, professional service is advisable.

Drying performance is poor; E12 displayed, often with long drying times and hot cabinet.
