No. Knives indicated as "Dishwasher safe" are the most prepared for this type of washing since they are made with synthetic handle, however, this does not mean that they cannot have some type of technical problem such as loss of polish, expansion and rivets falling, expansion and separation of scales, rust stains even on stainless steel, etc..., due to the very high temperature at which these devices work, therefore, get better conservation and durability of our knives by not washing them in the dishwasher, always do it by hand with soft sponge and soap and dry them afterwards.
