An OK machine for the money

3/5
So far, the dishwasher seems to be cleaning all my dishes, plates, cutlery etc. well, but it seems to be leaving water on the metal items that I use in the oven like baking trays, pans etc. which makes them go slightly rusty on the back due to the water pooling. I have read the instructions and I have an adequate amount of rinse aid / salt etc.
