A dishwasher and sump arrangement thereof

A dishwasher for washing items comprising:

• a washing chamber comprising a bottom wall, lateral walls and an aperture for a closing door;
• one or more racks for the items to be washed;
• at least one spray assembly for spraying liquid onto the items placed in the one or more racks;
• a sump arranged at the bottom wall of the washing chamber for receiving liquid from the washing chamber, the sump comprising an inner lateral wall extending around a sump axis (X) and a bottom wall;
• a circulating circuit associated to the sump to recirculate liquid from the sump to the at least one spray assembly, wherein the circulating circuit comprises a circulating pump having an inlet hydraulically communicating with the sump;
• a filtering group received in the sump and hydraulically arranged upstream the circulating pump for filtering liquid flowing from the sump to the circulating pump;
• a draining circuit associated to the sump to drain liquid outside the dishwasher, wherein the draining circuit comprises a draining pump having an inlet hydraulically communicating with the sump;
• wherein the inner lateral wall of the sump comprises two or more apertures arranged around the sump axis (X) and hydraulically communicating with the circulating pump inlet through at least one liquid channel, wherein the at least one liquid channel is delimited either by:
• a first further lateral wall of the sump and the inner lateral wall, wherein the first further lateral wall is external to the inner lateral wall so that the inner lateral wall is arranged between the first further lateral wall and the sump axis (X);
• or
• a first further lateral wall of the sump and a second further lateral wall of the sump, wherein the first further lateral wall is external to the inner lateral wall and the second further lateral wall is external to the inner lateral wall so that the inner lateral wall is arranged between the first further lateral wall and the sump axis (X) and the first further lateral wall is arranged between the second further lateral wall and the inner lateral wall.
