• Check that the dryer is receiving proper 240V power by verifying the circuit breaker is in the ON position and has not tripped
• Reset the dryer by switching the circuit breaker OFF for 60 seconds, then switching it back ON to clear any temporary error codes
• Remove and clean the lint filter thoroughly before each load and inspect for damage or tears
• Inspect the exterior exhaust vent opening to ensure it is not blocked by lint, debris, or bird nests
• Check the dryer door latch to confirm the door closes completely and latches securely
• Verify you are not overloading the dryer drum, as this restricts airflow and can trigger heating errors
• Inspect the flexible exhaust ductwork behind the dryer for kinks, crushes, or blockages that restrict airflow
• Ensure the dryer has adequate clearance around all sides for proper ventilation
• Run a test cycle with a small load of damp towels to see if the error repeats
• If error persists after these checks, contact a certified Miele service technician for professional diagnosis and repair
