Electrolux Dryer: error code EF1

Professional Repair Guide

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.

Urgency: Medium
