I really wouldn’t use a dishwasher.
The combination of high temperatures and the salt could really do some damage.
A couple of years ago I bought a set of Global knives and Global state on their website do not put in the dishwasher. However this instruction was not included in the box of knives.
Guess what? My wife put a few in the dishwasher and they were in a right state. Pitted blades and in some cases chunks out of the edge of the blade. Completely ruined which when you have just spent a few hundred quid it is not what you want to see.
Good news was that as the instructions were not in the box with the rest of the boxes in Selfridges they accepted this and replaced them all.
So be careful!
