ASKO Dryer Error Code Clean auto filter

The Clean auto filter message is a scheduled maintenance reminder built into Asko heat pump dryers. It appears based on an interval set in the service menu and indicates that the auto filter, the water filter used in the heat pump condensate system, is due for cleaning. This is not an error indicating a mechanical failure. Cleaning the filter and resetting the interval counter in the service menu will clear the notification.

The alert is a maintenance reminder, so the dryer will typically continue to operate. However, a clogged auto filter can reduce heat pump efficiency and extend drying times, and prolonged neglect could place additional strain on the system. It is best to clean the filter promptly when the message appears.

If the filter only needs cleaning, there is no parts cost involved. If a technician is needed to perform the service menu reset or inspect the system, expect a service call fee generally in the range of $80 to $150 depending on your location. If the auto filter itself is damaged and requires replacement, parts and labor costs will vary but typically fall in the $50 to $150 range for the repair.

Locate and remove the auto filter according to your model's access procedure, then clean it of any lint, debris, or mineral deposits. After the filter is cleaned and reinstalled, the maintenance interval counter must be reset through the service menu to dismiss the alert. If you are not familiar with accessing the service menu, a qualified technician can perform the reset.

A standard power cycle or user-level reset will not clear this maintenance notification. The interval counter that triggers the alert must be reset specifically through the service menu. Cleaning the filter without performing this reset will leave the message active on the display.
