How To Prevent Stainless Steel Getting Rusty In The Dishwasher?

I have a Hotpoint SDW80 dishwasher.
It’s very good but on the normal program (the one I use the most) leaves the stainless steel like pots, cutlery and so on labelled ‘dishwasher safe’ rusty.
Is there anything that I can do to prevent that happening? Do I have to stop the program towards the end when the drying time is active, would be that OK or I have to wait till the program has completed?
Any other suggestion?
