If your Asko dryer steam function is not working, the most likely cause is a failed control board or main control board that is not sending power to the water inlet valve or steam generator, so start by inspecting the control board for burned components, scorch marks, or loose connectors. If the board looks OK but the generator has power while the inlet valve does not, the steam generator itself is the next candidate. After that, check the simple stuff: make sure the water supply hose is connected to the dryer and the Y connector at the washer, and confirm there is water pressure. A clogged or damaged steam nozzle at the rear interior can block mist from entering the drum, and finally the water inlet valve can fail electrically; use a multimeter to test it for continuity. This covers the common causes when your dryer steam not working or steam fresh not working.

01 - Asko Dryer Control Board
If no power is getting to either the dryer's water inlet valve during the steam cycle or the steam generator, then it's likely the dryer's control board is defective and the cause of the steam function problem. The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component to help determine if the part should be replaced.

If no power is getting to the dryer's water inlet valve during the steam cycle, but power is reaching the steam generator, then it's likely the steam generator is defective and will need to be replaced.
The water supply hose needs to be connected from the home's water supply to the water inlet valve on the dryer. The water line is usually connected to a “Y” connector and shares the same cold-water supply as the washer. Refer to the owner's manual for water hookup instructions.

05 - Asko Dryer Nozzle
The nozzle, normally located at the rear interior of the dryer, may be damaged or clogged with debris and unable to allow the steam to enter the drum area. Inspect the nozzle or any damage or obstruction and replace if necessary.
The dryer's water inlet valve provides the water necessary for the steam function to work. If there is no mist coming from the nozzle when the valve is energized, it's likely the inlet valve is defective. You can use a multimeter to test the valve for electrical continuity. If the valve tests negative for continuity, you'll know the part has failed and will need to be replaced.
