  • Controller 230 controls flow regulating valve 900 to stop supplying washing water after a predetermined time elapses. This operation is referred to as "nozzle pre-washing". This "nozzle pre-washing” aims at washing of the outer peripheral surface of nozzle cover main body 721, and exhaust of cool water or the like staying in flow passages after hot water tank 245.
