Should the washer or dryer be placed on top?

You should always place the dryer on top of the washing machine – and never the other way around. This is simply because a washing machine is too heavy to be placed on top of the dryer. This means that if you already have a washing machine, it is important that you do not buy a dryer that is deeper than your washing machine. Therefore, always check the dimensions to ensure that the width and depth match before purchasing.
