Screw on one of the roller on upper tray broke Tim J. • Bend, OR • December 28, 2014 Appliance: KitchenAid Undercounter Dishwasher KUDS01DLSS6 My Repair & Advice Replaced complete roller- screw,wheel and axel. Easy job Just recently I had to replace upper spray arm. I ordered assembly from you and was completely satisfied with your service and price, that was over 1/2 of what local appliance repair dealer wanted. Very satified with how to do video on this project Was this review helpful to you?
