Dryer steam function not working

If your dryer’s steam function is not working, the most likely culprit is a failing control board or main control board stopping power to the steam components. Start by visually inspecting the board for burned components or shorted areas since control boards are hard to bench-test. If the board looks intact but the steam cycle still gets no power, the steam generator itself is next in line—if the generator isn’t getting the correct voltage or is defective it won’t produce steam. Before replacing parts, confirm the dryer’s water supply is hooked up at the Y fitting and the inlet hose is open, since a disconnected line is a common simple fix. Also check the internal nozzle for clogs or damage that would block mist from entering the drum. Finally, if the nozzle is clear but you see no mist when the inlet valve is energized, use a multimeter to test the dryer water inlet valve for continuity and replace it if it fails.

01 - 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.

02 - Dryer Main 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 main 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.

04 - Water supply not connected.

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.

Common

05 - 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.

06 - Dryer Water Inlet Valve

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.
