To make securely detectable an abnormal draining usually in a draining motion after a washing process, by detecting the water level after stopping a drain pump in a system to control a water feed means, a washing mechanism and the drain pump based on the output of a water level detecting means.
At the time of dish washing, when a start switch is operated, the valve of a water feed means 27 is opened by a controller to feed washing water into a washing room 3. Next, when the turning-on of a water level detecting means 18 is judged, a water feed valve 27 is closed and a washing pump 10 is actuated to start dish washing. After completion of the washing process, a drain pump 11 is actuated to discharge washing water in the washing room 3. After the draining process, for instance for 40 seconds, the drain pump is stopped. Whether the water level detecting means 18 is turned off or not is judged and, when it is judged not in OFF operation, it is judged an abnormal draining since the water level in the washing room 3 does not descend to be lower than a prescribed water level H and an abnormality is reported.
