This installation is in a house just moved into. The existing dishwasher has been installed behind a fitted cupboard door, i.e. pull down the door to open the dishwasher. The problem is that the door will only drop to about 25 degrees above horizontal as the bottom inside metal of the door comes into contact with the curved metal part of the main body. Is there some adjustment somewhere or has it just been installed incorrectly? No documentation came with the machine.
