The error code made it pretty easy to diagnose the issue. It had been acting up for a month or two prior. Finally, the door lock would not engage (you could hear the ‘clunk’ when that happened properly) Watched a great video that AppliancePartsPros.com had and was able to change the switch out in just 20 minutes. I found another issue that I fixed as well when the lower cover was off. A wiring harness had come loose from its strap and was running on the base of the washer. During the agitation and spin cycle I could see it running. Eventually, that would have caused a serious problem. Reattached with zip tie and all was good.
