Product review (5 stars): Like other reviewers mention, this provides a quick fix for an (unfortunately) common issue.
We have a Maytag Centennial washer with auto water level sensing and experienced the problems others have described -- the machine started agitating immediately upon starting a cycle, rinse cycles were off, etc. I used the "blow through the clear tube" trick several times to prolong the original sensor switch's usefulness...and eventually the problem got worse. I happened to be standing near the washer when it was filling...and filling...and filling. It started to overflow and if I hadn't switched the machine over to the spin cycle I'd have had a huge mess on my hands.

Anyway, this is a long way of saying that the new switch has resolved these problems. The washer functions as it should. The part swap is easy, though it's also easy to lose the springy clips that hold the control panel.

For now. I'd love to give this product -100 stars because I shouldn't need it, but that's not the part's fault. I'll certainly try any other manufacturer besides Maytag/Whirlpool when I replace this washer. It's ridiculous that the problem appeared so early in the machine's life (just after 1 year).
