James for Model Number GU2300XTVQ0 I am looking for a replacement bottom rack fo my wifes Whirlpool dishwasher, Part #AP3873720. My question is...what is the material it is constructed of, reason being we have only had the washer for going on three years and the rack is rusted out. It' only the 2 of us and that's not much service for $118.00 James
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 # W10727679. Tomato (acid) based foods will create the rust issue you have. This is the best service bulletin we could find. Thank You. Read More... Answered by AppliancePartsPros.com | Friday, June 8, 2012
