I'm going to be installing an integrated washing machine in my new kitchen. Just need to stick the washing machine in place and fit the hinges on to the integrated door. However, there's currently a 3-4 inch gap between the top of the washing machine and the bottom of the work top it's going in under. The legs of the washing machine only extend about an inch so this won't help much filling the gap. Does anyone know if this gap is ok or do I need to place the washing machine on some sort of base. It's currently sitting on a flat, tiled floor. I can alter the position of the hinges so the door covers the gap but it just seems the top of the machine should be flush with the work top? Just wondering am I missing something, should this gap be there or not?
