What Does Error EF1 Mean?

The Electrolux dryer EF1 error indicates a ventilation or airflow issue, often caused by a blocked exhaust system or a faulty airflow sensor. This error usually appears shortly after starting a cycle, resulting in the dryer shutting off early or failing to heat properly. Even after cleaning lint and vents, the EF1 error may persist, signaling a need for further investigation.

Common Symptoms:

  • Error appears on display during or shortly after cycle start
  • Dryer may shut off early or not heat properly when EF1 occurs
  • Error persists even after cleaning visible lint and vents

Possible Causes

  • Blocked or restricted exhaust/vent system (high)
  • Faulty vent airflow sensor or thermistor reporting incorrect readings (medium)

How to Fix Error EF1

DIY Fix Clean lint screen and check exterior vent

  1. Unplug the dryer from power.
  2. Remove and clean the lint screen thoroughly.
  3. Inspect the external vent hood for blockages, including animal nests or debris.
  4. Ensure the vent flap opens freely.

DIY Fix Inspect and clear internal vent hose

  1. Disconnect the vent hose from the back of the dryer.
  2. Use a vacuum or dryer vent brush to remove lint and debris from the hose.
  3. Reattach the hose securely, ensuring no sharp bends restrict airflow.
  4. Run a test cycle to check if the error persists.

Technician Only Test and replace thermistor or airflow sensor

  1. Disconnect power and access the internal thermistor/airflow sensor as per model service manual.
  2. Use a multimeter to measure thermistor resistance and compare with expected values.
  3. Replace the sensor if readings are out of specification.

Parts needed: Thermistor or vent airflow sensor

🛑 When to Call a Pro:
  • If vent and lint cleaning does not resolve EF1 error
  • If internal sensor testing/replacement is beyond user skill level
  • If water or moisture is found inside vent pathways indicating other faults
