Dishwashing machine, preferably for home use, with an improved architecture

A dishwashing machine comprises a stationary housing with an open front face and at least two structures for supporting wash load items. The support structures are able to slide horizontally with respect to the housing through the open front face of the housing. At least one of the support structures is capable of sliding horizontally jointly with a door, which closes the open front face of the housing, and is adapted to move in a substantially vertical direction along an inner surface of the door. The inner surface of the door is able to accommodate the front bulk of at least another one of the remaining support structures.
