Blocked or restricted air pathways/ventilation

How to Identify: Airflow feels weak, vents blocked by lint or objects; error persists after filter cleaning.

Part: Ventilation ducts/air paths

Plinth filter too wet when refitted

How to Identify: Error occurs soon after cleaning; filter was not sufficiently dried before reinsertion.

Part: Plinth filter

Overloaded drum or excessive dampness

How to Identify: Error only occurs with large, very damp loads; smaller/less damp loads run normally.

Part: Drum/load handling

Faulty auxiliary fan or airflow monitoring system
