What the symptom can mean
A maintenance reminder and a detected operating condition may use different indications. The exact model and programme outcome are needed before interpreting the message as a blocked part.
When does it appear?
Note whether the message is present before starting, comes on during use or appears at end. Include whether the programme completed and whether the laundry was warm, damp or dry.
Use the installed model
Find the product reference on paperwork or a normally accessible label. A generic online filter warning is not enough to select parts or justify dismantling a different dryer format.
