Hi, does anyone know if KitchenAid/Hobart KDI-18 racks will fit in my KitchenAid KUDI 220T0 dishwasher? The KUDI (probably Whirlpool/circa 1990) came with our house nearly 20 years ago, and it is a real workhorse, but the racks are in very bad shape and getting worse by the day. I found an older (Hobart era) KitchenAid KDI-18 offered for sale as parts online, with racks in pretty good shape. The size, shape and set-up of the racks and the attached upper rinse mechanism look very similar, but should I wait and keep looking for a KUDI 220T0 instead? (I fear that if the rest of them are like mine, they are never going to die.)
