ASKO Dryer Error Code Clean filter

The Clean filter message on an Asko heat pump dryer is a scheduled maintenance notification triggered by a cycle or time interval set in the service menu. It indicates that the evaporator filter assembly, consisting of the net filter and foam filter, and the evaporator coil itself are due for cleaning. This is a routine reminder, not a fault code, and the dryer is still functional. Addressing the cleaning promptly protects heat pump efficiency and drying performance.

The dryer will typically continue to operate when this message is displayed, but running the machine with heavily clogged filters is not recommended. Restricted airflow through a dirty evaporator filter reduces drying efficiency and increases cycle times. Prolonged operation in this condition can place added strain on the heat pump compressor over time.

If the issue only requires cleaning the filters and evaporator, the cost is minimal and limited to your time or a service call fee ranging from roughly $75 to $150 depending on your location. If the foam filter or net filter needs replacement due to damage, parts costs are typically in the $15 to $50 range depending on the component. A technician visit to perform cleaning and reset the service menu counter would generally fall in the $100 to $200 range total.

To resolve the notification, clean both the net filter and the foam filter that make up the evaporator filter assembly, and also clean the evaporator coil surface inside the machine. Once the physical cleaning is complete, the interval counter must be reset through the service menu to clear the reminder. If you are not comfortable accessing the service menu, a qualified technician can perform the reset after confirming the cleaning is done.

A standard power cycle or consumer-level reset will not clear this notification because it is controlled by an interval counter in the service menu. The counter must be reset through the service menu after the evaporator filter and evaporator have been properly cleaned. Resetting the counter without performing the cleaning does not address the underlying maintenance need.
