Dishrack

James for Model Number GU2300XTVQ0

Answer Hi James. The racks are constructed with vinyl racks. Rack Kit - Gray- Item Number: 4396840RC. Made by Whirlpool. Please consider this as an option. The rack is part # 8561749. Tomato (acid) based foods will create the rust issue you have. This is the best service bulletin we could find. Thank You.

Answer MT, the dishrack 8561749 is the original lower rack used on your appliance. Unfortunately, we do not have a listing of the color and using our picture it is hard to tell. From it, it looks to be a silver however, this being the original rack it will be the same as the current one in your unit now. Thanks.
