I first noticed the problem when I pulled dirty dishes out of the dishwasher after I thought I had run it. I set it to run again and noticed that it made some noises when it started filling up with water, but then went silent when normally you could hear the water spraying inside. I did some research online to find on a forum that my model has a pump motor which will typically poop out after 3 years and can be replaced with a part from this website. I watched the YouTube video demonstrating the motor replacement and it seemed straightforward enough. I ordered the part along with a new grommet and the dishwasher cleaner. Everything arrived and I was able to replace the motor without issue. Everything is back to normal.
