Problems solved by technology
[0005] However, while the dishes are being washed, foreign matter keeps accumulating on the filter, clogging it
[0006] In addition, the foreign matter accumulated on the filter device creates resistance to the flow of wash water through the filter device, thereby reducing the flow rate of wash water
As a result, the amount of wash water supplied to the wash water ejector decreases, and therefore, the washing performance of the dishwasher decreases, and an excessive load is applied to the wash water pump unit for pumping the wash water
[0007] In addition, since the foreign matter continuously accumulated on the filter device adheres to at least one surface of the filter, removal of the foreign matter may be difficult, and the foreign matter may rot to generate an unpleasant smell in the cleaning chamber

Provided is a method of controlling a dishwasher. The dishwasher includes a washing chamber accommodating a dish, a sump storing washing water, and supplying the washing water to the washing chamber, and a filter part provided to the sump, and filtering a foreign substance from the washing water. In the method, a first pump is driven to perform a washing or rinsing process, the first pump is stopped and a second pump is driven for a first set time to perform a discharging process, after the washing or rinsing process, the second pump is stopped and the first pump is driven for a second set time, and the first and second pumps are stopped.
Description
technical field [0001] The present disclosure relates to a dishwasher and a method of controlling the same. Background technique [0002] Dishwashers spray wash water on dishes to remove food residue or food residue from them. [0003] This dish washing machine includes: a sump for receiving clean washing water, which is located on one side of the washing chamber; and a washing water sprayer, which sprays washing water to the dishes in the washing chamber, thereby washing the dishes. tableware. Washing water used to wash dishes is recovered into the sump, and then is supplied to the washing water sprayer again through a filtering device in the sump. [0004] When the washing of the tableware is completed, all the washing water is drained from the washing chamber and the sump. At this time, the foreign substances filtered by the filter device may be discharged to the outside of the dishwasher together with the washing water. [0005] However, while the tableware is being ...
