Yes! Our Pro Collection probes are waterproof and dishwasher safe. Alpha Collection probes are water-resistant, not waterproof, though you shouldn't see durability or safety issues if you put your probes in the dishwasher.
Whenever you can, though, we still recommend washing your probes by hand, especially if you're experiencing charging or connectivity issues. Probes often develop a thin, hard-to-see film from grease and smoke that requires a more abrasive cleaning method to remove than your dishwasher can do on its own, which can prevent the probe from making proper contact with the charging dock.
