No single answer as it depends on engine type and whether its a simple "water rinse" or "maintenance turbine cleaning action" as "water wash" has been used to describe both tasks. But in general, for a basic water rinse some engine OEMs allow it to be performed while the engine is running and some don't and usually doesn't require much prep to accomplish. On the "mx cleaning side" it can involve blocking various engine control and signal systems to prevent cleaning solution contamination plus repetitive water rinses to remove the cleaning solution prior to engine run. Regardless, most if not all engine OEMs provide written procedures for both tasks.
