What Does Error F066 Mean?

The Miele dryer F066 error indicates a ventilation issue, often due to obstructed airflow or clogged filters. This can lead to the dryer overheating and interrupting the drying cycle. Common causes include dirty plinth and lint filters, restricted air paths, or inadequate ventilation space around the appliance.

Common Symptoms:

  • Drying program is interrupted and the dryer stops with F066 displayed
  • Dryer may overheat or cycle heater on/off due to restricted airflow
  • Error appears after refitting filter if too wet or improperly seated

Possible Causes

  • Insufficient airflow due to obstructed ventilation grille or small/densely enclosed laundry space (high)
  • Dirty, clogged, or improperly cleaned plinth (sockelfilter) or lint filters (high)
  • Restricted air paths within dryer (heat exchanger and internal airways clogged with lint) (medium)

How to Fix Error F066

DIY Fix Check and clean plinth and lint filters

  1. Turn off and unplug the dryer.
  2. Remove the plinth filter according to the user manual.
  3. Rinse the plinth filter and lint filters under running water until all lint and debris are removed.
  4. Ensure the filter is thoroughly dried before reinserting.
  5. Inspect for visible damage and replace if deformed or worn.

DIY Fix Ensure proper ventilation around the dryer

  1. Clear any objects blocking the ventilation grille under the door.
  2. Ensure the dryer is not installed in a confined, poorly ventilated space.
  3. Open a window or door in the laundry area during drying cycles on condenser/heat pump models.

Technician Only Inspect and clean internal air paths and heat exchanger

  1. Disconnect power to the dryer.
  2. Remove access panels to reach internal air paths, heat exchanger, and ducts.
  3. Use appropriate tools (vacuum with brush, compressed air) to clear lint and debris.
  4. Verify that all air paths are unobstructed and reconnect panels.

Parts needed: heat exchanger cleaning access, air duct interior

Technician Only Replace damaged filters or components causing airflow restriction

  1. Verify condition of plinth filter, lint filters, and any air path gaskets or guides.
  2. Replace any filters that are warped, torn, or not sealing correctly.
  3. Test dryer post-replacement to confirm F066 no longer occurs.

Parts needed: plinth filter, lint filters

🛑 When to Call a Pro:
  • If error persists after thorough cleaning and ventilation checks
