During the leveling operation, the driving members 51 of the adjusting mechanisms 5 at the four corners of the base 11 will operate simultaneously. Since the nut 512 is threadedly connected to the output shaft 511 of the driving member, the nut 512 will carry the pressure sensor 52 and the second elastic member 53 to operate downward, causing the compression amount of the second elastic member 53 to gradually change. Since the pressure sensor 52 is fixed to the upper end of the second elastic member 53, the pressure sensor 52 will feel the pressure during the compression of the second elastic member 53. When the pressure on the pressure sensor 52 reaches the set value, the driving member 51 stops running, and the four corners of the washing machine have been adjusted to the desired state. The pressure values ​​of the adjusting mechanisms 5 at the four corners of the base 11 are set to equal values. When each corner stops running, the pressure on the second elastic members 53 at the four corners is the same, and the dishwasher is in a horizontal state.
