Do not listen to DW and stick one of my custom knives in a dishwasher. Even stabilized wood will not withstand the heat and water of a dishwasher.
A carbon steel knife will rust from using a dishwasher, S30V steel is stainless and will probably survive a dishwasher, but the handle scales will not.
One member on this forum sent me a knife to repair that had went though a dishwasher. I repaired that one for free, but from here on out it will cost you for any repair due to neglect and that includes using a dishwasher to clean the knife.
