PROBLEM TO BE SOLVED: To provide a washing device of bathroom members for spraying washing water inside a bathtub from washing nozzles installed on a bottom wall of the bathtub and to securely prevent troubles caused by blocking by detecting the blocking and prohibiting carrying out of washing even when washing nozzles or washing piping are blocked by freezing or rubbish.SOLUTION: A watercourse is switched to a circulation side and hot water is poured into the bathtub, and thereafter the watercourse is switched to a washing and communicating state and a water level measurement L1 is output by a water level sensor (S21-S26). The watercourse is switched again to the circulation side and hot water is poured N2 into the bathtub, and thereafter the watercourse is switched to the washing and communicating state and a water level measurement L2 is output by the water level sensor (S27-S30). When water level change corresponding to the N2 is detected in the water level measurement, there is no blocking. When the change is not detected, it is determined that there is the blocking and start of washing is prohibited. |
