Behind the Washer and Dryer clearance

Appliance parts like are generally specific to the manufacturer and possibly model. My usual approach, which has served me well, is:

1. Find the manufacturer's service website.
2. Do a parts search there, based on the model # and part description. Ideally, check the existing part for a label.
3. If that doesn't work, look for a parts diagram of your model. Often these include part IDs expressly for the purpose of ordering replacements.
4. Based on the part number identified in step 2 or 3, search on google and ebay for the part. Usually you can find it from a third-party retailer for significantly less than ordering direct from the manufacturer.

You might also try a local appliance repair parts store -- they may be able to guide you to find the right part if they are familiar with your brand of appliance.

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.
