Product review (5 stars): Saved money on washing machine repairs
My washing machine started overflowing and with a little research, I discovered what the problem was and how to fix it...gotta love YouTube. I am pretty mechanically inclined and am an IT/electrical engineer so this wasn't difficult for me to understand. I removed the old part and discovered that the rubber diaphragm had a small puncture, which is what was causing the sensor to not register the water level.

I ordered one of these and replaced the part and I fixed the problem. Saved lots of money calling a repairman.
