How to I disconnect water pipe connected to Asea Cylinda 1200 dish washer?

Hi.
I want to replace my old Asea Cylinda 1200 dish washer. But first I need to drag the whole dish washer out of the cabinet but I can' move it outward as I believe it must be connected to a water pipe and power cord. I can't see either one of them from inside the dish washer. I have no visibility of both sides and the back of the dish washer as it is totally embedded below the kitchen bench and next to a wall.

Please advise.


Thanks
John
