In general, soap dispensers are designed to be integral to the machine. While the machine was put together by human hands and therefore should be able to be disassembled in the same way, it may very well be more of a task than you wish to take on.
This answer assumes the dispenser is basically functional and you have no reason other than cleanliness to want to remove it.
I suggest you clean the dispenser in place and forego removing the unit. I think you will be happier in the long run with this approach.
