Steven K Garden Grove , CA January 21, 2015 The water level switch was difficult to rotate and was starting to distort the knob insert I watched a video on the Appliance Parts Pros website which showed easy to follow, step by step instructions on how to replace the water level switch on my Whirlpool top-load washer. Excellent video!! Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
