The product may tend to shake during drying if it is not level.
Try this
If the product is not level; a slight shaking may occur during the drying process.
By default, a technician would ensure a level installation, but if the customer moves or switches the dryer direction at will, the product may become unsteady, causing noise and vibration.
Level check procedure
Make sure the product does not wobble when you hold the top surface corners diagonally and try to rock it.
Leveling method
If the product is not level, a spanner or a suitable tool can be used to level it.
Rotating an adjustment leg clockwise, will raise that particular corner of the machine. Contrary to that, rotating a leg counterclockwise, will lower the product.
After adjusting, hold the top surface corners diagonally again and try to rock the machine to ensure that there is no more wobbling.
