I have a Frigidaire Dishwasher FDBB4365FS0. Lately it has been making some atypical noises while washing. The dishes seem to be cleaning the same, but the sound is not the same. My guess is this is the motor possibly wearing out? I know that isn’t much to go on, but are there some troubleshooting steps I can do to determine the issue?

Also, I found a video on replacing a motor for a similar model, and it looks relativly straightforward. Would anyone recommend a do-it-yourself vs. paid professional do this?

Thanks.
