A dishwasher comprising a body; a washing tub provided in the body and wherein the washing process is performed; a door which enables the washing tub to be isolated from the outer environment and which is opened from top to downwards by rotating around a horizontal axis; said door having a closed position, a partially open position and an open position; a locking mechanism which enables the door to be locked onto the body; a control unit which enables the door to be pushed and opened partially upon the completion of the washing and drying processes so as to be distanced for a certain amount from the body; a hinge which enables the door to be movably connected onto the body; and a hinge arm which extends from the door towards the bottom of the washing tub, the locking mechanism comprising at least one spool provided under the hinge arm, a first spring provided in the horizontal plane under the washing tub, a movement member which is positioned in the first spring, a stopper against which one end of the movement member bears in the closed and partially open position of the door, and a transmission member which is connected to the hinge arm at one end and which is connected to the movement member at the other end by passing through the spools characterized by the movement member comprising a first channel which is in the form of a hollow cylinder, a second channel in the form of a hollow cylinder having a smaller diameter than that of the first channel, and an abutment which is arranged between the first channel and the second channel, a compression member which moves between the first channel and the second channel during opening and closing of the door and which presses the transmission member so as to enable the same to move along the movement member, a protrusion which is provided on the compression member and which contacts the abutment in the partially open and open position of the door so as to prevent the transmission member from being released from the locking mechanism, whereby in the closed position of the door the protrusion is on the first channel, in the partially open position of the door the protrusion contacts the abutment and in the open position of the door the contact between the movement member and the stopper is interrupted. said door having a closed position, a partially open position and an open position; a locking mechanism which enables the door to be locked onto the body; a control unit which enables the door to be pushed and opened partially upon the completion of the washing and drying processes so as to be distanced for a certain amount from the body; a hinge which enables the door to be movably connected onto the body; and a hinge arm which extends from the door towards the bottom of the washing tub, the locking mechanism comprising at least one spool provided under the hinge arm, a first spring provided in the horizontal plane under the washing tub, a movement member which is positioned in the first spring, a stopper against which one end of the movement member bears in the closed and partially open position of the door, and a transmission member which is connected to the hinge arm at one end and which is connected to the movement member at the other end by passing through the spools characterized by the movement member comprising a first channel which is in the form of a hollow cylinder, a second channel in the form of a hollow cylinder having a smaller diameter than that of the first channel, and an abutment which is arranged between the first channel and the second channel, a compression member which moves between the first channel and the second channel during opening and closing of the door and which presses the transmission member so as to enable the same to move along the movement member, a protrusion which is provided on the compression member and which contacts the abutment in the partially open and open position of the door so as to prevent the transmission member from being released from the locking mechanism, whereby in the closed position of the door the protrusion is on the first channel, in the partially open position of the door the protrusion contacts the abutment and in the open position of the door the contact between the movement member and the stopper is interrupted.
