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
