Hisense rusty dishwasher

I bought a Hisense dishwasher in May 2022. It was not cheap. In May this year the plastic coating started coming off the racks. Apparently it's not covered under the warranty. Now there is rust all over the place and if I use it the dishes are covered in rusty water. This is ridiculous. The new racks are extremely expensive. I don't live near the coast and have never had rust issues with appliances before.
