Abstract: The present disclosure relates to a dishwasher having a heat pump, including a dishwasher body provided with a tub configured with a washing space therein and a sump provided at a bottom of the tub to temporarily accommodate washing water; a heat pump having a compressor, an evaporator, an expansion apparatus, and a sump condenser provided inside the sump to exchange heat with washing water inside the sump; and a controller that controls the heat pump to be driven so as to increase the temperature of the washing water inside the sump. As a result, a heating time of washing water may be shortened, thereby suppressing washing time from being prolonged.
