Abstract: Sanitary cleansing apparatus 20 is provided with attachment state sensor 180 for detecting the state of attachment to toilet bowl 21. When OFF signal is output from attachment state sensor 180, first closing valve 137a is closed at step S82 and power supply to cleansing water heater 129 is stopped at step S84; shower nozzle 24 is finally stored in standby position. Therefore, troubles are fairly prevented since shower nozzle 24 is stored in standby position with inhibition of water spouting function when sanitary cleansing apparatus 20 is detached from toilet bowl 21.

Abstract: Detected temperature TMs of warm water thermistor 28a, presence of any or no wire break in nozzle unit 12, attachment completion data by attachment state sensor 17, continuous in-use data by timer 16 and data related to other cleansing function parts and units are read (step S52). If there any abnormal temperatures and wire breaks, these data and other detection data in various conditions are stored in backup RAM while unnecessary data (data at tests in production processes) which are considered as not contributing to investigation of causes of troubles are reset according to function part data, such as attachment completion data and continuous in-use data (step S62). This modification eliminates utilization of data obtained at tests in production process, not during continuous use, as data for investigation into causes when trouble occurs and thus enhances reliability of data.
