Checked HOB dishwasher unit. Per customer, dishwasher is leaking from right corner, bottom. Pulled door down & found debris & lime build up in door gasket & around door. Cleaned build up out of door gasket & around door. Removed bottom cover to check for any leaks. Found sanitizer solenoid corroded, possible leak from there. Will order new gasket & solenoid. Unit still leaking around right side of doors after cleaning out. 1/15/18 Replaced right side door hinge parts, sanitizer sensor & door gasket, tested okay. Found wash arms stiff bushings need replaced. Will obtain 2 wash & rinse arm bushings & return. Noted wash arm plugged, cleaned & don't think we need any more parts at this time.
