How to Troubleshoot & Replace Whirlpool AP5989731 / W10852420 Water Level Switch Pressure Switch

I used the schematics, parts lists, Q & A section, and how to videos and also chat to diagnose the problem. But the problem was intermittent. So I had to replace the two probable parts responsible. Also in the process of moving the machine a tub support pad had broken and fallen out. As a note: it really isn't necessary to remove the tubs to replace the tub support pads. I couldn't get the tubs out. So I tried to do it without removing them and was successful. As a result I purchased a spanner wrench that I really didn't need. Other than that everything went smoothly. 

This is my first time working on a washing machine I own on my own. The parts website configuration made it very easy to find the correct part and its location with the schimatics it provided. I order it with 2 day shipping and it arrived just as I got home from work on the scheduled day of delivery. It made my wife VERY happy that I was able to fix the machine so fast! Thank you and I will be using you again for future appliance parts!
