To provide a washing machine excellent in handleability with a small noise caused by the vibration by using an inclination detecting means that can detect the inclination of the washing machine installed at a low price.
The inclination detecting means installed on a water tank determines by its detecting output whether a rotational axis of a rotary drum placed inside the water tank is within a specified range (S11) and in case it detects any defect in the positioning of the water tank 1 is assigned to an error flag (S13). Any input to a start key of the washing machine is determined (S14) and in case the judgment S14 is positive it is notified to a user by ringing an alarm sound (S17) when the judgment (S15) whether the value of the error flag is 1 is positive. Thus the waggling of the rotational axis caused by its misalignment or its colliding with the water tank is prevented and the noise-free and highly secure washing machine of higher quality can be achieved.
