Dishwasher and method of controlling the same

A dishwasher comprising:

• a circulation pump that supplies water to a nozzle;
• a drainage pump that discharges the water;
• a driving current supplier including an inverter that outputs a driving current and a current distributor that selectively supplies the driving current to the circulation pump and the drainage pump by switching the supply of the driving current between the circulation pump and the drainage pump;
• a controller that transmits a driving control signal to the driving current supplier;
• and
• a door opening detector that detects whether a door of the dishwasher is an open state or a closed state, and, when the door is detected to be open, transmits a door opening detection signal to the controller and the driving current supplier, and when the door is detected to be closed, transmits a door closing detection signal to the controller and the driving current supplier,
• wherein, when the door closing detection signal is received by the controller and the driving current supplier, the current distributor is controlled based on the driving control signal from the controller,
• wherein, when the door opening detection signal is received by the controller and the driving current supplier while the driving current is supplied to the circulation pump, the current distributor stops the supply of the driving current to the circulation pump and supplies the driving current to the drainage pump regardless of the driving control signal from the controller, so that an operation of the circulation pump is stopped from the current distributor before the inverter stops the output of the driving current, and
• wherein the driving current supplier further comprises a door signal receiver that receives the door opening detection signal from the door opening detector.
