Product review (5 stars): Perfect Fit For Whirlpool Duet Sport Model #WFW8300SW03 | EASY Installation!
Our bellow had a small tear in the front that was allowing water to leak out during the cycle, and after searching the web I realized this is something we could do ourselves and save $300+ on a service call, etc..

One thing that was frustrating was finding the right bellow for our model, so I hope that this will help others with the Whirlpool Duet Sport Model #WFW8300SW03. This bellow works perfectly, and the installation was a breeze.

Note: The three little holes on this bellow should be on the bottom when installing.

The worst part about the installation was the variety of tools needed, however it was only THREE as follows:

Phillips Screwdriver (one screw under the front electrical panel and bellow clamp)
1/4" Socket OR Nut Driver (for removing the front panels and the top panel)
Small Start Bit OR Driver (not exactly sure what size, as I have a complete set. used to remove one screw under the dispenser tray)

Optional:

Flat head screwdriver (for removing the first tension clamp)

Other than that friends, the installation was super easy and everything fit together well. Make sure you double check the bellow is sealed along each edge before installing the clamps.

I would highly recommend this product, and highly recommend you do-it-yourself and save time/money.
