Product review (5 stars): mine didn't break!
This sensor was easy to install and works well with my washing machine.  Unfortunately it was not the point of failure which caused my washing machine to fail; but it was easy to install and putting it in didn't hurt anything.
ultimately, the problem in my LG wm3987hw washing machine leaving clothes soaked in water during the dry cycle was determined to be the water input solenoid assembly.

Nothing wrong with this part. It works fine, but it might not be the part you need.
there are methods of testing these available online. If you have a voltage/ohms meter, these will read a different resistance across the pins depending on how much air pressure is exerted on the hose connection.
I should have tested before throwing parts at my washer; this wasn't a failure point in my washing machine.
also sometimes a hose can get clogged with lint and make funny readings so it might be worthwhile to blow out the air line connected to this sensor before you go and replace it.
