Myra C Spencer , IA January 24, 2020 Appliance: Model GU1200XTKBO Rusting of bottom dish rack. Ordered new rack. Replacement part weighed only 2/3 as much as old rack. Wonder if different material used in it. Would have likeed to have seen instructions sent with rack. Went on line and viewed the video several times.
