A dishwasher (100) comprises a cabinet (1), a tub (11) for providing a washing space, a sump (13) for providing a space in which the washing water is stored, located below the tub, racks (191, 193) provided inside the tub (11), providing a space in which washing targets are received, spray arms (3, 5) for spraying the washing water to the racks, a pump (8) for supplying the washing water stored in the sump to the spray arms, and at least two insulating units (91, 93, 95) for connecting the pump with the sump to allow the pump to be spaced apart from a bottom of the cabinet at a predetermined distance and attenuating transfer of vibration generated in the pump to the sump.
