Abstract: Provided herein is a spray arm arrangement for a dishwasher having: a support having a hub portion; and a spray arm having at least one arm portion with at least one spray nozzle, and a generally tubular mounting portion connected to the arm portion. The mounting portion may have first and second bearing surfaces bearing against the hub portion, with the first bearing surface being located at a shorter axial distance from the arm portion than the second bearing surface. The first bearing surface may be located within the hub portion proximate the axial end of the hub portion facing towards the arm portion, and the second bearing surface may include a projection which axially extends from said mounting portion into said hub portion.

Abstract: A spray arm assembly for a dishwasher, comprising a spray arm (12; 74) comprising a plurality of spraying nozzles (40, 42, 60; 76), and support means (16; 56; 78) comprising a mounting element (18; 50; 80) for mounting the support means within the dishwasher and a support member (20; 54; 82) on which the spray arm (12; 74) rests during periods of non-use. The spray arm assembly is characterized in that it further comprises —first supplemental outlet means (24, 48, 58; 92) to direct, during periods of use, liquid to between the support member (20; 54; 82) and the spray arm (12; 74) so as to form a liquid layer between the support member and the spray arm, on which liquid layer the spray arm floats during rotation, and —second supplemental outlet means (28; 86) to direct, during periods of use, liquid to between the spray arm (12, 74) and a guiding surface (34) provided at the support means, so as to stabilize rotation of the spray arm.

Abstract: If a key (A) which is already assigned with authorization to a first object (A1) is placed in the vicinity of a second object (B), and this object (B) is placed in an initialization state, the data (X) of the key (A1) is written into the second object (B), or the data (Y) of the second object (B) is written into the key (A1). The key (A1) is then assigned with authorization to the second object (B). In this way, the key can be assigned to further objects (A, C) as authorized by means of an initialization.
