Researched the problem online and found the appliancepartspro.com website. It suggested that the problem was the Rotor Position Sensor Switch. I ordered the part and paid extra for two day guaranteed shipping, because I was leaving on a week long business trip and needed the washer fixed before I left. The part arrived the next day. I watched the installation video, which was super informative. Then followed the step shown in the video. Took less than a half hour to replace the switch. Put the machine back together and ran a spin and drain cycle. The washer worked with no problems.
I don’t typically leave reviews butt I was extremely impressed by the quickness of the shipping and the quality of the installation video.
