A sump assembly of a dishwasher stores water to be supplied to spray nozzles. The sump assembly includes a sump housing for storing water; a heater assembly for heating the stored water; and a water supply pump for pumping the heated water from inside the sump housing above the heater assembly. The water supply pump has an impeller, provided inside the sump housing and disposed above the heater assembly, for forcing the heated water out of the sump housing. The sump housing of the sump assembly is provided with a heater port, which is an opening formed in a lateral side one of the sump housing for receiving the heater assembly, so that a manual operator can unload the heater assembly from and load the heater assembly into the sump housing, while acting externally with respect to the sump assembly. The heating assembly includes a heating unit, installed in the heater port, for generating heat energy; and a packing plug, fitted to the opening of the heater port, for receiving the heating unit; and a pressurizing mechanism, configured to compress the packing plug, for sealing the opening of the heater port.

An apparatus and method for remotely controlling household appliances connected to a home network. A power line and a network processor is installed in each household appliance, enabling a household appliance user to remotely control the appliances from a place outside of as well as inside a home. Information about all conditions of the household appliances can be displayed on a screen displayable household appliance so that the user can recognize the operations of the appliances even during spare moments. A low-price built-in server is installed in each household appliance to assign the corresponding appliance a unique IP address simply over the Internet to be controlled according to an external user control command. A home server is connected to each of the household appliances such that the corresponding appliance receives a control command, sent in transit by a user from a mobile terminal.
