Error code F7 indicates a heating element or thermal sensor failure on your Asko dryer. This error prevents the dryer from generating heat needed to dry your clothes and requires attention to restore normal operation.
• Dryer runs but produces little to no heat
• Clothes remain wet or damp after a complete cycle
• Dryer stops mid-cycle and displays F7 error code
• Drum rotates normally but no warm air is generated
• Error code appears repeatedly after power reset
• Dryer may emit burning smell or no smell at all during operation

Possible Causes
• Faulty heating element that has burned out or failed
• Defective thermal cut-off fuse that has tripped and won't reset
• Malfunctioning temperature sensor or thermistor unable to detect heat
• Broken heating element relay or contactor in control board
• Airflow obstruction causing thermal sensor to trigger safety shutdown
• Failed high-limit thermostat preventing heating cycle activation
• Wiring issues or loose connections to heating element circuit
• Control board malfunction affecting heating element signals

Safety Checks You Can Do
• Remove and thoroughly clean the lint filter, checking for lint buildup that restricts airflow
• Inspect the external dryer vent hood outside your home for blockages, bird nests, or debris
• Trace the vent hose from dryer to exterior and check for kinks, dents, or compression points
• Ensure the dryer door closes completely and latches properly with no gaps
• Verify you are using an appropriate drying cycle with heat setting, not air-only mode
• Check that the dryer is properly plugged in and the outlet is functioning with a test light
• Unplug the dryer from the wall outlet for 60 seconds, then plug it back in to reset the system
• Confirm the dryer has adequate clearance (at least 1 inch) on all sides for proper ventilation
• Run a test cycle after each troubleshooting step to see if error clears
