Why is my washing machine so loud during the spin cycle?
The spin cycle is normally the loudest part of the washing program. To compare the sound of your machine with others, you should consider whether it's designed to be extra quiet or not, and whether it has a high-speed spin cycle or not.

My washing machine has a 1200 RPM high speed spin cycle, but it's designed to be quiet so it's not very loud anyway. It also has the option to run the spin cycle at a slower speed, which makes it even more quiet.

You can buy rubber washers designed to be placed under the feet of the washing machine, which will reduce the vibrations in your rack.

Although the spin cycle is noisy, you should listen if there is a banging noise or if it's just loud. If there is a banging noise the clothes may be unevenly balanced (overload?), or there may be something wrong with the suspension so that it can't absorb the vibrations.
