I guess that there is more steel and less stainless in the knives!! The best stainless steel is marked 18/10 I believe.
Found this......
Dishwashing machines provide a welcome relief from the task of washing up but to maintain knives in good condition a few simple precautions are necessary. Special hardenable stainless steels are generally used for knives to give them a lasting edge but these steels can become slightly pitted or corroded if left repeatedly and for too long in contact with moisture.
- Whenever possible wash knives immediately; do not leave them wet overnight and do not subject knives to the ‘rinse and hold’ cycle. The use of the dishwasher as a dirty storage cabinet causes many cases of knife corrosion.
- As soon as the dishwasher has completed its cycle, remove the knives and wipe them dry. It is particularly undesirable to leave them overnight in the damp atmosphere of a dishwasher.
- Observe the dishwasher manufacturer’s instructions concerning the type and quality of detergent used and the method of loading cutlery in the compartments provided.
- Water with a high salt content is particularly corrosive to stainless steel. Dishwashers are often fitted with water softeners that must be regenerated with salt. After adding salt, make certain that the machine is put through the programme recommended by the supplier before washing knives in the machine.

True stainless steel makes for terrible knives. In high quality knife making, very little nickel and chromium are added to the steel - this makes for a much stronger knife that can keep a sharp edge for a long time.
Sharp knives of any type should never be put in the dishwasher - the chemicals and very hot water will dull the edge, damage the handle and rust the knife.
Wash with soapy water soon after use, rinse, dry with a towel and keep in a block.
I hope that helps.

If they are truly stainless they should not contact the makers by email and ask them. I have good German rust free knifes and they are regular in the dish washer with all salts. the only problem is the glasses. when the salt is wrong. salt is the major cause of rust. but if really stainless, should be rust free. but some makers get of with this word. and should say like the German and Swiss Knifes Rust Free

cheap stainless steel knives can rust in the dishwasher, especially if you don't have a water softner

my guess is your dishwasher detergent has bleach in it and bleach will go through the surface of stainless steel if the Steel is thin and cheap.

It could be that you need more rock salt in the reservoir.
