yes, as long as the washing machine is not over 60cm wide or deep.

The 2 metal plates (lower and upper) are continuous.

yes, in principle it is possible. The stability of the base is sufficient in any case. But the instructions officially advise against it. I also have a washing machine and a tumble dryer on top of each other on the base. If both appliances are well connected, there should be no stability problems (wobbling or the like).
