After chatting with an appliance parts pro person, I was able to narrow down which parts I needed to buy. I ended up replacing the water inlet valve, the cold water reservoir and a drain tube. I have never really repaired anything like this before, but as a recent widow, I knew I needed to learn. Appliance Parts Pros made it super simple with their videos. It took me quite a bit longer than the people in the videos, but that was just because I rewatched sections of the videos several times to make sure I didn't mess things up.
I would definitely use this website again if I need to fix an appliance. I highly recommend Appliance Parts Pros.
