Product review (5 stars): Fixed the "uL" problem with our Whirlpool Cabrio!
Whirlpool Cabrio was making a loud knocking with the "uL" code.  No matter what we did, it would do it again - small or large loads.. although larger loads sometimes helped prevent the issue.  Bought these for that Cabrio washer, but looks to work with just about any Whirlpool, Kenmore etc of similar make, just double check. (part AP5985113 is the equivalent).  Took about 30-45 minutes to install.  We did the install with 2 people, but I think if it had to be done, 1 person would be fine.  It was an easy repair after watching a couple of YouTube videos, and I have no experience in appliance repair.  No special tools are needed, besides a putty knife or similar pry-tool.

Cheaper here than other competing sites/vendors, and probably saved a ton of money fixing it myself!  Also learned a little something about washing machines in the process.

Tried a load immediately after with no problems, and has been working perfect ever since!
