In a method for manufacturing a dishwasher having at least one component and at least one bitumen mat provided on the component for noise deadening and/or sound insulation of the component, a usable, flowable and reactively-hardenable bituminous mixture is applied upon the bitumen mat and/or component such as to form at least one adhesive bead. The adhesive bead is partly surrounded by at least one area which is free of the reactively-hardenable bituminous mixture. Before the hardening of the bituminous mixture, the component and the bitumen mat are pressed together and thereby glued to one another.

The method of claim 1, wherein the adhesive bead has an average width of at most 20 mm. 24. The method of claim 1, wherein the adhesive bead has an average width of at most 15 mm. 25. The method of claim 1, wherein an average distance of a gap between two adjacent sections of the at least one adhesive bead amounts to at least 1.0 times an average width of the at least one adhesive bead. 26. The method of claim 1, wherein an average distance of a gap between two adjacent sections of the at least one adhesive bead amounts to at least 1.2 times an average width of the at least one adhesive bead. 27. The method of claim 1, wherein an average distance of a gap between two adjacent sections of the at least one adhesive bead amounts to at least 1.5 times an average width of the at least one adhesive bead. 28. The method of claim 1, wherein an average distance of a gap between two adjacent sections of the at least one adhesive bead amounts to at most 4.0 times an average width of the at least one adhesive bead. 29. The method of claim 1, wherein an average distance of a gap between two adjacent sections of the at least one adhesive bead amounts to at most 3.0 times an average width of the at least one adhesive bead. 30. The method of claim 1, wherein an average distance of a gap between two adjacent sections of the at least one adhesive bead amounts to at most 2.0 times an average width of the at least one adhesive bead. 31.
