Drying function does not start or stops quickly with E06; clothes remain wet after drying cycle

Safety first: Unplug the appliance and allow it to cool completely before working near the dryer heater.

Step-by-step checks:

• 1. Clean airflow and condenser:
  • Remove the lower front panel or condenser access flap (model dependent).
  • Take out the condenser unit (if removable) and rinse it thoroughly under running water to remove lint.
  • Clean lint from ducts, fan housing, and around the dryer heater area.
• 2. Check the dryer heater and thermostats:
  • Access the dryer heater assembly (often at the rear or side of the drum housing).
  • Disconnect the heater connectors and measure resistance; if open circuit, replace the heater.
  • Test the thermal cut-out and thermostats for continuity; any open device (that is not resettable) should be replaced.
• 3. Inspect the dryer NTC sensor:
  • Locate the NTC on the air duct or near the heater.
  • Measure its resistance at room temperature and compare with Siemens specifications.
  • Replace if readings are out of range or unstable.
• 4. Wiring and control module:
  • Check connectors for heat damage or loose pins.
  • If all components test good but E06 persists, the power module heater relay or triac may be defective.

When to call a technician: If heater replacement requires major disassembly or if control board faults are suspected, professional service is recommended.
