What to Check First
- Not all washers and dryer can be stacked. Please make sure your models are compatible and stackable before attempting to stack the set.
- DO NOT attempt the stacking procedure with only one person.
- When stacking the dryer on top of the washer, it is imperative and mandatory to purchase the optional Stacking Kit accessory and install it on the washer. Failure to do so risks causing noise and malfunction and may result in bodily harm and damage to product.
- Stacking is only possible when sizes of both dryer and washer are the same.
- Checking and Choosing the Proper Location 1 Clean the floor before installation. Make sure to select solid and smooth ground. 2 Two or more people are needed for moving and unpacking the washing machine. 3 Allow for sufficient space between the walls and the washing machine for installation.
- Washer is bound to vibrate slightly. If the washer side panels rub against a wall and vibrating while in spin cycle, both vibration and vibration noise will get amplified throughout the house. Best recommendation to avoid this scenario is to leave sufficient space between the sides of the washer and the walls and make sure flooring is extra rigid.
- LASTLY VERY! VERY IMPORTANT! make sure the floor underneath stacked units is INCREDIBLY RIGID! Any play or softness that could allow washer to wobble will have combined units vibrate exponentially and reverberate throughout the house. Nobody wants that!
- Some select LG washer and dryers sets are able to be stacked allowing you more space in your laundry area.
- 1 Clean the floor before installation. Make sure to select solid and smooth ground.
- 2 Two or more people are needed for moving and unpacking the washing machine.
