We're sorry to hear your dishes weren't left spotless like we expect from the many quality checks we have in place, Jen. To get the best results, be sure your water is at least 120 degrees Fahrenheit/49 degrees Celsius. Also, when loading the machine, be sure all items will get the full spray and that your spray arms aren’t blocked. We'd like to get more information to help, as well as share your experience with our Quality team. When you have a minute, please get in touch with us at (800) 765-5516.
