The message on screen
The TD85.11XX (T411VD) shows E4 with the text please clean filters or call service. In the error table the problem is labelled control unit failure, yet the first thing the manual asks of you is filter cleaning.
Cleaning the door net filter
Asko says to clean the door net filter after every drying cycle. The routine is as follows:
Open the filter housing.
Pull the net filter out.
Scrape off the lint.
Put the filter back.
The Cleaning and Maintenance chapter of the instructions for use covers filter care. Never run the dryer without the door net filter, or with a damaged one.
Order of events
Turn the dryer off and on, clean the filters, and see whether E4 clears. If it is still displayed, the next step is a technician visit.
E4 still lit after the filters are clean? Phone (415) 993-3547 and mention both the code and the cleaning, plus the TD85.11XX model details. More on Asko dryer repair is on our site.
Model compatibility: Asko reuses codes across series and model years, so E4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E4 is a control unit failure on the TD85.11XX (T411VD); the manual asks you to clean the filters first.
Important safety warning. Do not attempt repairs involving electrical components, water lines, sealed cooling systems or anything behind a panel. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
