If your Samsung dryer steam function not working, the most likely culprit is a faulty control board or main control board that is not sending power to the steam generator or water inlet valve. Start by checking the control board for obvious burn marks or shorted components, since the board cannot be easily bench tested. If power does reach the steam generator but no steam is produced, the steam generator itself is likely bad and will need replacement. Less likely but easy to check, make sure the water supply hose is connected and the home water valve is open, then inspect the rear nozzle for clogs or damage that would stop mist from entering the drum. Finally, if the nozzle is clear and the inlet valve never produces mist when energized, the water inlet valve may have failed; you can test it for electrical continuity with a multimeter.

01 - Samsung 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.

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 - Samsung 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.
