Product review (5 stars): This fixed my washer!
I have a Whirlpool Cabrio WTW5500XW0 and it was not completing the wash cycle.  The lid lock light would flash at the end of the wash cycle, and it would hesitate for a while, then rinse with the lid unlocked.  It would just pour water in, then pump it out.  No spinning or agitating after the end of the wash cycle.  This part fixed everything and it works as good as new.  After reading online, it sounds like what was happening was the washer did not know what gear it was in.  Something in the old one wore out, and was not sending the proper signals back the the washer's computer.

Now it's good as new, and it spins a lot during the cycle, and spins at the end of the wash cycle where it used to start flashing the lid lock light.  I hope this review helps someone!
