Depends on your dishwasher. Even in top rack after a couple of washes PETG it warped for me on standard wash. If you run a dry cycle or sterilization cycle on your dishwasher forget it. If its anything precise (I printed a lid with threads) a single standard wash is enough to ruin precision with subtle warping. Also the dishwasher can introduce moisture into gaps created by printing that can grow mold or bacteria. I think we would all love better options for dishwashable printed materials, but I would argue PETG is not really it.
