Nadene L Binghamton , NY July 20, 2016 The water level knob on my washing machine was broken I installed the new knob. It was very simple...and now my washing machine is working again. I bet I saved at least $100 if I had called someone to come fix it! Thank you! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
