Hisense Dishwasher Bad Quality

We bought a Hisense dishwasher H13DESS in 2022, 9 months in the racks started rusting. Hisense refused to supply new ones as this is not covered under warranty. so we bought new Racks HIS985136 ref number to quote... April 2023. Now 3 years later the racks is again rusting with absolute zero assistance to why this is happening from Hisense ( we also just use Finish products in the machine) Their response is you have to buy new ones... So are their quality so bad that every 2 years you have to replace racks? We had a samsung before lasted us 11 years before we decided to replace due to electrical issues. Is this the type of product that you want to sell to you consumers and can't give them answers don't even return calls? *** new Reference number. I believe if the client has paid the first time and it happened again that this is now the suppliers issue to sort out at their own cost!
