Ran system through diagnostic tests twice to confirm error codes and operation. Based on error code and some online research, decided that it was a faulty drain pump. After determining which part I needed by using the parts diagrams on AppliancePartsPros.com, I ordered the part from them and replaced it by following steps in the repair video they had posted on their site. The hardest part of the job was getting enough water out of the tub to be able to move it around as needed to replace the part. Wet/dry vac made this a lot less painful. I could've pulled the tub to completely drain it, especially since I had just replaced the tub seals and bearings a month or so earlier. I could've also taken it outside where it could be laid flat, but would've had to move a lot of stuff out of the laundry room and taken a couple of doors off to get it out. I instead was able to remove enough water with the shop vac that I was able to tip it forward and support it at an angle that allow me to reach the pump but keep from dumping water everywhere.
