I have stacked Maytag units. Leave the washer door ajar when not using it or mold will form. This is recommend for all front loading units.

At my age the washer, which is always on the bottom due to vibration issues, can be hard to reach the back of as they are so low. It is not possible to put a cabinet beneath it as the dryer would then be to high.

But I love this set up and will never go back.

You will find a 'connection' package is necessary to keep the dryer in place. These are quite expensive at the dealer but the same package is almost nothing at Amazon.

If you have it delivered then ask the delivery people to lift the drying in to place and set it up. They are quite heavy when lifting them straight up.
