What is this symptom?

Important Tips for Miele Models

Miele models may require opening and closing the door and pressing OK after filter cleaning to clear the filter message; failure to do this can make the message persist.

Possible Causes

Soiled lint/fluff filters (door filter/plinth filter) or incomplete cleaning

How to Identify: Message to clean filter persists and airflow is reduced, lint buildâ€‘up visible on filters

Part: Lint filters (door filter and plinth/heat exchanger filters)

Failure to reset message after cleaning filter

How to Identify: Filter is clean but message remains until reset/OK is pressed

Part: Control panel message logic

Poor airflow due to clogged airways/blocked vents

How to Identify: Indicator light to clean airways/filters persists, reduced drying performance

Part: Airflow pathways including vents/ducting

Faulty filter sensor or electrical fault

How to Identify: Message persists despite clean filters and proper reset; occasional error codes/other faults

Part: Filter presence/airflow sensor or control board
