A dishwasher includes a dishwashing container accommodating items to be washed. A first hydraulic arrangement is provided to wash the items by a dishwashing fluid and includes a spray device arranged in the dishwashing container, a sump arranged below the dishwashing container, a filter device configured to filter the dishwashing fluid in the dishwashing container and/or the sump, and a circulating pump configured to circulate the dishwashing fluid to the spray device. A second hydraulic arrangement is provided for cleaning the filter device by a cleaning fluid. The second hydraulic arrangement includes the filter device, the sump, a pump arrangement, a storage device for holding the cleaning fluid, a cleaning device for spraying at least one segment of the filter device with the cleaning fluid, and an auxiliary pump arranged between the storage device and the cleaning device for applying pressure to the cleaning fluid.

A dishwasher having a treating chamber with one or more sprayers through which liquid is recirculated into the treating chamber, whereby the impact of the spray emitted from the sprayers impacts the structure forming the treating chamber to generate noise. Damping material is applied to structure forming the treating chamber to reduce the sound level of the impact exterior of the dishwasher.
