An impressive achievement....
I have a 2004 SQ, put into service in 2008. No issues or repairs, though I did add a fluorescent light panel from an Amana dryer. Used 5-6 times a week for the last 11 years, I've never taken anything out that I thought wasn't clean and well rinsed. Even ground-in dirt and grass come out in the "short" wash time with a quality detergent.
