Hello, I suspect it is not an XXL appliance as opposed to Jelimi's machine. For a dishwasher with a standard height of about 82 cm, the distance between the pivot point of the dishwasher door and the cabinet door is greater. This also increases the angle of intersection of the planes in which the two doors lie. Consequently, with a dishwasher of standard height, the gap at the top when opening is smaller than with an XXL. However, Behjälplig is also intended for standard dishwashers.
(The sale of BEHJÄLPLIG was certainly not discontinued without reason.)
If I have identified the correct cause, at the moment I see lowering the machine and filling the space between the dishwasher and the countertop with a strip as the only solution.
