Two parts, Pressure Valve and Inlet Valve only took me 10 minutes to change out. Funny incident, when I reconnected the water hose ad turned the water on, my hose had a pinhole in it! Took me longer to drive to the home store to get a new hose than it took to get my machine fixed and running. The videos were great!!! Helped me confirm the parts I needed and showed the location and ease of doing the repairs myself. GREAT!
