Thanks for asking, Jenna!
If your washer and dryer are stacked, make sure they are installed with a compatible Samsung stacking kit (SKK-8K) and matching dryer, which helps secure the units together. It's also important that the washer is installed on a level floor, as an uneven surface can cause movement and vibration during operation.
For the best fit and a smooth setup, working with a professional installer can help ensure everything is installed properly.
We hope this helps.
