Safety first: Disconnect the dryer from mains. Moving fan blades can cause injury.

Check air intakes: Ensure that the front and rear air intake grilles are not blocked by dust, lint, or objects.
Access blower housing: Remove the front or rear panel (depending on model) to reach the blower fan. Inspect for lint clumps, socks, or other items caught in the fan.
Inspect fan wheel: Check that the fan impeller is firmly attached to the motor shaft and not cracked or missing blades. Replace the fan wheel if damaged.
Test fan motor: Spin the fan by hand; it should rotate freely. If stiff or noisy, the motor bearings may be worn. Test the motor windings with a multimeter and replace the fan motor if defective.
Reassemble and test: After clearing obstructions and replacing any faulty parts, reassemble the dryer and run a cycle. If E13 persists, the control board may be misreading fan speed or current and should be checked by a technician.

Dryer displays E13 and may stop shortly after starting; sometimes accompanied by unusual fan noise
