Turned the washer on its front to access underneath the machine. Turned the belt and heard a small squeak in the water pump. Looked online and found others saying the water pump can cause loud noisy operation and that it was easy to fix. It was. After getting the part (just one day after ordering it by the way) it took maybe 30 minutes to repair. I probably could have done it even faster but I dropped my screws a number of times. I would suggest magnetic tools since it can be tough to find the screws once you drop them down into the washer.
