When a predetermined amount of water is supplied from the water supply valve, the floating body switching valve opens the circulation path due to the levitation force and closes the ventilation path. Then, since the water level detecting element is energized by the floating body switching valve, it can be detected that the predetermined washing water is supplied by the water supply valve. Further, when the cleaning water is supplied by the operation of the cleaning pump, the cleaning water pressure of the cleaning water is applied to the floating body switching valve, so that the pressure detecting element can detect the cleaning water pressure of the cleaning water. Therefore, when the cleaning water is not supplied to the circulation path due to a malfunction of the cleaning pump or the like, a predetermined pressure is not applied to the pressure sensing element via the floating body switching valve, and the control device determines that the cleaning pump is malfunctioning or the like. Therefore, the heating element can be de-energized, and a user or the like can be notified of an abnormality of the dishwasher / dryer.

Therefore, the operation of the floating body switching valve can be used to detect the amount of washing water supplied, or to detect a malfunction of the washing pump, etc., and to notify the user of an abnormality in the dishwasher. It has the effect of being able to.
