Drying cycle stops early; no heat and E09 displayed

Safety first: Unplug the appliance and let it cool fully. Do not bypass thermal cut-outs.

Step-by-step checks:

• 1. Thoroughly clean lint paths:
  • Remove and wash the condenser (if user-removable) under running water.
  • Vacuum lint from air channels, fan housing, and around the heater.
  • Clean the door filter and any secondary lint filters.
• 2. Check dryer fan:
  • Access the fan motor (usually near the heater or condenser).
  • Ensure the fan wheel turns freely and is not obstructed.
  • If the motor is noisy, seized, or not running during drying, replace the fan motor.
• 3. Test thermal cut-outs:
  • Locate the thermostats and thermal fuses on the heater housing.
  • Test for continuity; any open, non-resettable device must be replaced.
• 4. Control module check:
  • If overheating recurs after cleaning and component replacement, the control may be overdriving the heater.
  • Control module replacement may be necessary.

When to call a technician: If repeated overheating occurs or if you cannot access the heater safely, contact Siemens service.
