Abstract: There is a dishwasher including a tub defining a washing space and accommodating dishes; and a heat pump apparatus configured to heat wash water introduced into the tub. The heat pump apparatus may include a compressor configured to compress refrigerant; a condenser to which refrigerant is introduced from the compressor, the condenser configured to heat water introduced into the tub; an expansion valve to which refrigerant is introduced from the condenser, the expansion valve configured to expand refrigerant; a first evaporator to which refrigerant is introduced from the expansion valve, the first evaporator configured to evaporate refrigerant by absorbing heat from room-temperature air; and a second evaporator to which refrigerant is introduced from the first evaporator, the second evaporator configured to discharge refrigerant to the compressor and evaporate refrigerant by absorbing heat from stored water.
