Electrolux Dryer: error code EF1
What is this symptom?
If your Electrolux dryer is displaying the EF1 error code, it indicates a ventilation issue. This often occurs when the dryer shuts off shortly after starting or when airflow is restricted. Common causes include a blocked lint screen or ventilation path, which can significantly impact the dryer's performance. Addressing this issue promptly ensures efficient drying and prevents further damage.
Important Tips for Electrolux Models
- Electrolux official documentation lists EF1 as a ventilation blockage error and recommends checking lint filter and exhaust tube for restrictions
Possible Causes
Blocked or restricted lint screen/ventilation path
How to Identify: Dryer displays EF1 shortly after starting; visible lint buildup on filter or in vent; restricted airflow from external vent
Part: Lint filter and exhaust vent system
Obstructed blower wheel or internal airflow path
How to Identify: Dryer shows EF1 and reduced airflow even after external vent cleaning; debris around blower housing; blower wheel does not spin freely
Part: Blower wheel/air manifold

User Suggested Solutions
-
Inspect and clean the moisture sensor. Locate the sensor inside the dryer drum, usually near the lint filter. Use a soft cloth and mild detergent to clean any residue. Ensure the sensor is properly connected.
-
Check and clear the venting system. Disconnect the dryer from power, remove the vent hose, and inspect for lint buildup. Clean the vent hose and the vent duct leading outside to ensure proper airflow.
-
Inspect wiring and connections. Unplug the dryer and remove the back panel to check for loose or damaged wires. Reconnect any loose wires and replace damaged ones as necessary.
